Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.


This chapter explains how to create Cisco ONS 15454 SDH low-order circuits and tunnels, high-order circuits, Ethernet circuits, and virtual concatenated (VCAT) circuits. For additional information about ONS 15454 SDH circuits, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Table 6-1 defines ONS 15454 SDH circuit creation terms and options.

Table 6-1 ONS 15454 SDH Circuit Options 

Circuit Option
Description

Source

The circuit source is where the circuit enters the ONS 15454 SDH network.

Destination

The circuit destination is where the circuit exits an ONS 15454 SDH network.

Automatic circuit routing

Cisco Transport Controller (CTC) routes the circuit automatically on the shortest available path based on routing parameters and bandwidth availability.

Manual circuit routing

Manual routing allows you to choose a specific path, not just the shortest path chosen by automatic routing. You can choose a specific VC4, VC3, VC11, or VC12 for each circuit segment and create circuits from work orders prepared by an Operations Support System (OSS).

Low-order tunnel

Low-order tunnels allow VC3, VC11, and VC12 circuits to pass through an ONS 15454 SDH without using low-order cross-connect resources on the cross-connect cards. Low-order circuits using tunnels use low-order cross-connect capacity only at the source and destination nodes. One low-order tunnel can carry three VC3s, and each VC3 can contain a VC3 circuit span or 21 VC11 or VC12 circuit spans.

Low-order aggregation point

Low-order aggregation points (LAPs) allow low-order VC11, VC12, and VC3 circuits to be aggregated into a VC4 for handoff to non-ONS 15454 SDH networks or equipment, such as interoffice facilities (IOFs), switches, or digital access cross-connect systems (DACS). The VC4 grooming end of the LAP requires an STM-N card. LAPs can be created on MS-SPRings, 1+1, or unprotected nodes, but cannot be created on SNCP nodes.


ONS 15454 SDH circuits are either low-order or high-order circuits. Table 6-2 shows the circuit source and destination options for low-order VC3 circuits.

Security Level

Provisioning or higher



Step 1 Complete the "DLP-D60 Log into CTC" task at an ONS 15454 SDH on the network where you will create circuits. If you are already logged in, continue with Step 2.

Step 2 From the View menu, choose Go to Network View. Wait for all the nodes that are part of the network to appear on the network map. (Large networks might take several minutes to display all the nodes.)


Note If this is the first time your computer has connected to this ONS 15454 SDH network, the node icons are stacked on the left side of the graphic area, possibly out of view. Use the scroll bar under the network map to display the icons. To separate the icons, press Ctrl and drag and drop the icon to the new location. Repeat until all the nodes are visible on the graphic area.


Step 3 Verify node accessibility. In the network view, all node icons must be either green, yellow, orange, or red.

If all network nodes do not appear after a few minutes, or if a node icon is gray with "Unknown" under it, do not continue. Look at the Net box in the lower right corner of the window. If it is gray, log in again, making sure not to check the Disable Network check box in the CTC Login dialog box. If problems persist, see Chapter 5 "Turn Up a Network" to review the network turn-up procedure appropriate for your network topology, or refer to the Cisco ONS 15454 SDH Troubleshooting Guide for troubleshooting procedures.

Step 4 Verify DCC connectivity. All nodes must be connected by green lines. If lines are missing or gray in color, do not continue. See Chapter 5 "Turn Up a Network" and follow the network turn-up procedure appropriate for your network topology. Verify that all nodes have DCC connectivity before continuing. If DCCs need to be created, complete the "DLP-D363 Provision Regenerator-Section DCC Terminations" task.

Step 5 Click the Alarms tab to view alarm descriptions. Investigate and resolve, if necessary, all critical (red node icon) or major (orange node icon) alarms. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide to resolve alarms before continuing.

Step 6 From the View menu, choose Go to Home View. Verify that the node is provisioned according to your site or engineering plan:

a. View the cards that appear in the shelf map. Verify that the ONS 15454 SDH cards appear in the specified slots.

b. Click the Provisioning > General tabs. Verify that the node name, contacts, date, time, and Network Time Protocol/Simple Network Time Protocol (NTP/SNTP) server IP address (if used) are correctly provisioned. If needed, make corrections using the "DLP-D140 Change the Node Name, Date, Time, and Contact Information" task.

c. Click the Network tab. Verify that the IP address, Subnet mask, Default Router, Prevent LCD IP Config, and Gateway Settings are correctly provisioned. If not, make corrections using the "NTP-D201 Change CTC Network Access" procedure.

d. Click the Protection tab. Verify that protection groups are created as specified in your site plan. If the protection groups are not created, complete the "NTP-D203 Modify or Delete Card Protection Settings" procedure.

e. If the node is in an MS-SPRing, click the MS-SPRing tab. (If the node is not in an MS-SPRing, continue with Step f.) Verify that the following items are provisioned as specified in your site plan:

MS-SPRing type (2-fiber or 4-fiber)

MS-SPRing ring ID and node IDs

Ring reversion time

East and west card assignments

(4-fiber MS-SPRings only) Span reversion and east/west protect card assignments

If you need to make corrections, see the "NTP-D40 Provision MS-SPRing Nodes" procedure for instructions.

f. Click the Security tab. Verify that the users and access levels are provisioned as specified. If not, see the "NTP-D30 Create Users and Assign Security" procedure to correct the information.

g. If Simple Network Management Protocol (SNMP) is used, click the SNMP tab and verify the trap and destination information. If the information is not correct, see the "NTP-D87 Change SNMP Settings" procedure to correct the information.

h. Click the Comm Channels tab. Verify that DCCs were created to the applicable STM-N slots and ports. If DCCs were not created for the appropriate STM-N slots and ports, see Chapter 5 "Turn Up a Network" and complete the turn-up procedure appropriate for your network topology.

i. Click the Timing tab. Verify that timing is provisioned as specified. If not, use the "NTP-D85 Change Node Timing" procedure to make the changes.

j. Click the Alarm Profiles tab. If you provisioned optional alarm profiles, verify that the alarms are provisioned as specified. If not, see the "NTP-D71 Create, Download, and Assign Alarm Severity Profiles" procedure to change the information.

k. Verify that the network element (NE) defaults listed in the status area of the node view window are correct.

Step 7 Repeat Step 6 for each node in the network.

Step 8 Complete the appropriate circuit creation procedure from the NTP list in the "Before You Begin" section.

Stop. You have completed this procedure.


NTP-D334 Create an Automatically Routed Low-Order VC11 Circuit

Purpose

This procedure creates an automatically routed low-order VC11 circuit, which means that CTC chooses the circuit route based on the parameters you specify and on the software version.

Tools/Equipment

The following cards must be installed at the circuit source and destination nodes: XC-VXC-10G and optical cards (STM-N, MRC-12).

Prerequisite Procedures

D127 Verify Network Turn-Up

Required/As Needed

As needed

Onsite/Remote

Onsite or remote

Security Level

Provisioning or higher



Note This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the "Network Element Defaults" appendix in the Cisco ONS 15454 SDH Reference Manual.



Note VC11 circuits can start and end only at optical cards.



Step 1 Complete the "DLP-D60 Log into CTC" task at an ONS 15454 SDH on the network where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2 Complete the following:

a. On the shelf graphic, verify that XC-VXC-10G cross-connect cards are installed in Slots 8 and 10.

b. Click the Provisioning > Cross-Connect tabs and set the Low Order Payload Type to VC-11 or VC-11 and VC-12 (Mixed Mode).

Step 3 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-D314 Assign a Name to a Port" task. If you want CTC to assign a name automatically based on circuit type, node name, and sequence number, continue with Step 4.

Step 4 From the View menu, choose Go to Network View.

Step 5 Click the Circuits tab, then click Create.

Step 6 In the Circuit Creation dialog box, complete the following fields:

Circuit Type—Choose VC_LO_PATH_CIRCUIT.

Number of Circuits—Enter the number of VC-11 circuits that you want to create. The default is 1. If you are creating multiple circuits with the same slot and consecutive port numbers, you can use Auto-ranged to create the circuits automatically.

Auto-ranged—This check box is automatically selected if you enter more than 1 in the Number of Circuits field. Auto-ranging creates identical (same source and destination), sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.

Step 7 Click Next.

Step 8 Define the circuit attributes (Figure 6-1):

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—Choose VC11.

Bidirectional—Leave checked for this circuit (default).

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.

Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.

Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.

Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task.

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Apply to drop ports—Check this check box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.


Note If ports managed into the Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to Unlocked-disabled,failed.


Protected Drops—Check this check box if you want the circuit routed on protected drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you check this check box, CTC shows only protected cards and ports as source and destination choices.

Figure 6-1 Setting Circuit Attributes for a Low-Order VC11 Circuit

Step 9 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task. Otherwise, continue with Step 10.

Step 10 Click Next.

Step 11 Complete the "DLP-D186 Provision a Low-Order VC11 Circuit Source and Destination" task.

Step 12 In the Circuit Routing Preferences area (Figure 6-2), choose Route Automatically. Two options are available; choose either, both, or none based on your preferences.

Using Required Nodes/Spans—Check this check box if you want to specify nodes and spans to include or exclude in the CTC-generated circuit route.

Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.

Review Route Before Creation—Check this check box if you want to review and edit the circuit route before the circuit is created.

Figure 6-2 Setting Circuit Routing Preferences

Step 13 Set the circuit path protection:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.

To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.

To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 16.


Caution Circuits routed on MS-SPRing protection channels are not protected. They are preempted during MS-SPRing switches.

Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within SNCP ring portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not check for node diversity.

Step 15 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP DRI, check the Dual Ring Interconnect check box.

Step 16 If you selected Using Required Nodes/Spans in Step 12, complete the following substeps. If not, continue with Step 18.

a. Click Next.

b. In the Circuit Route Constraints For Auto Routing area, click a node or span on the circuit map.

c. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit will be routed. Click spans twice to change the circuit direction.

d. Repeat Step c for each node or span that you wish to include or exclude.

e. Review the circuit route. To change the circuit routing order, choose a node from the Required Nodes/Lines or Excluded Nodes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.

Step 17 Click Next. In the VC LO Matrix Optimization page, choose one of the following:

Create VC LO tunnel on transit nodes—This option is available if the VC11 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC11 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.

Create VC LO aggregation point—This option is available if you are creating a VC11 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 network, choose one of the following:

VC4 grooming node is source-node, VC11 grooming node is destination-node—Creates the LAP on the VC11 circuit source node. This option is available only if the VC11 circuit originates on an STM-N card.

VC4 grooming node is destination-node, VC11 grooming node is source-node—Creates the LAP on the VC11 circuit destination node. This option is available only if the VC11 circuit terminates on an STM-N card.

None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.

Step 18 If you selected Review Route Before Creation in Step 12, complete the following substeps. If not, continue with Step 19.

a. Click Next.

b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.

c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "NTP-D335 Create a Manually Routed Low-Order VC11 Circuit" procedure.

Step 19 Click Finish. One of the following results occurs, depending on the circuit properties you chose in the Circuit Creation dialog box:

If you entered more than 1 in the Number of Circuits field and selected Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.

If you entered more than 1 in the Number of Circuits field and did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 6 through 18 for each additional circuit. After completing the circuits, the Circuits window appears.

Step 20 In the Circuits window, verify that the new circuits appear in the circuits list.

Step 21 Complete the "NTP-D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.

Stop. You have completed this procedure.


NTP-D335 Create a Manually Routed Low-Order VC11 Circuit

Purpose

This procedure creates a low-order VC11 circuit and allows you to provision the circuit route.

Tools/Equipment

The following cards must be installed at the circuit source and destination nodes: XC-VXC-10G and optical cards (STM-N or MRC-12).

Prerequisite Procedures

D127 Verify Network Turn-Up

Required/As Needed

As needed

Onsite or remote

Security Level

Provisioning or higher



Step 1 Complete the "DLP-D60 Log into CTC" task at an ONS 15454 SDH on the network where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2 Complete the following:

a. On the shelf graphic, verify that XC-VXC-10G cross-connect cards are installed in Slots 8 and 10.

b. Click the Provisioning > Cross-Connect tabs and set the Low Order Payload Type to VC-11 or VC-11 and VC-12 (Mixed Mode).

Step 3 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-D314 Assign a Name to a Port" task. If you want CTC to assign a name automatically based on circuit type, node name, and sequence number, continue with Step 4.

Step 4 From the View menu, choose Go to Network View.

Step 5 Click the Circuits tab, then click Create.

Step 6 In the Circuit Creation dialog box, complete the following fields:

Circuit Type—Choose VC_LO_PATH_CIRCUIT.

Number of Circuits—Enter the number of VC11 circuits that you want to create. The default is 1. If you are creating multiple circuits with the same slot and consecutive port numbers, you can use Auto-ranged to create the circuits automatically.

Auto-ranged—This check box is automatically checked if you enter more than 1 in the Number of Circuits field. Auto-ranging creates identical (same source and destination), sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.

Step 7 Click Next.

Step 8 Define the circuit attributes (Figure 6-1):

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—Choose VC11.

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.

Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.

Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.

Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task.

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Apply to drop ports—Select this check box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.


Note If ports managed into the Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to Unlocked-disabled,failed.


Protected Drops—Check this check box if you want the circuit routed on protected drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you check this check box, CTC shows only protected cards and ports as source and destination choices.

Step 9 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task. Otherwise, continue with Step 10.

Step 10 Click Next.

Step 11 Complete the "DLP-D186 Provision a Low-Order VC11 Circuit Source and Destination" task.

Step 12 In the Circuit Routing Preferences area (Figure 6-2), uncheck Route Automatically.

Step 13 Set the circuit path protection:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.

To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 17.

To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 17.


Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.

Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP, choose a Node-Diverse Path option:

Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired— Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not check for node diversity.

Step 15 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.

Step 16 Click Next. In the VC LO Matrix Optimization page, choose one of the following:

Create VC LO tunnel on transit nodes—This option is available if the VC11 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC11 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.

Create VC LO aggregation point—This option is available if you are creating a VC11 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto a VC4 for transport outside the ONS 15454 SDH network, choose one of the following:

VC4 grooming node is source-node, VC11 grooming node is destination-node—Creates the LAP on the VC11 circuit source node. This option is available only if the VC11 circuit originates on an STM-N card.

VC4 grooming node is destination-node, VC11 grooming node is source-node—Creates the LAP on the VC11 circuit destination node. This option is available only if the VC11 circuit terminates on an STM-N card.

None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.

Step 17 Click Next. In the Route Review/Edit area, node icons appear for circuit routing. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.

Step 18 Complete the "DLP-D187 Provision a Low-Order VC11 Circuit Route" task for the VC11 circuit you are creating.

Step 19 Click Finish. CTC compares your manually provisioned circuit route with the specified path diversity option you chose in Step 14. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path.

Step 20 If you entered more than 1 in the Number of Circuits field, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 6 through 19 for each additional circuit.

Step 21 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created are correct.

Step 22 Complete the "NTP-D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.

Stop. You have completed this procedure.

Step 7 Click Next.

Step 8 Define the circuit attributes:

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—Choose VC11.

Bidirectional—Uncheck for this circuit.

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.

Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.

Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.

Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task.

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.


Note If ports managed into the Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to Unlocked-disabled,failed.


Protected Drops—Check this box if you want the circuit routed to protect drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you check this box, CTC displays only protected cards as source and destination choices.

Step 9 Click Next.

Step 10 Complete the "DLP-D186 Provision a Low-Order VC11 Circuit Source and Destination" task.

Step 11 In the Circuit Routing Preferences area, uncheck Route Automatically. When Route Automatically is not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes are unavailable.

Step 12 Set the circuit path protection:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.

To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.

To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 16.


Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.

Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on an SNCP, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not check for node diversity.

Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.

Step 15 Click Next. In the VC LO Matrix Optimization page, choose one of the following:

Create VC LO tunnel on transit nodes—This option is available if the VC11 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC11 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.

Create VC LO aggregation point—This option is available if you are creating a VC11 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 SDH network, choose one of the following:

VC4 grooming node is source-node, VC11 grooming node is destination-node—Creates the LAP on the VC11 circuit source node. This option is available only if the VC11 circuit originates on an STM-N card.

VC4 grooming node is destination-node, VC11 grooming node is source-node—Creates the LAP on the VC11 circuit destination node. This option is available only if the VC11 circuit terminates on an STM-N card.

None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.

Step 16 Click Next. In the Route Review and Edit area, node icons appear so you can route the circuit manually. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.

Step 17 Complete the "DLP-D187 Provision a Low-Order VC11 Circuit Route" task for the VC11 circuit you are creating.

Auto-ranged—This check box is automatically selected if you enter more than 1 in the Number of Circuits field. Auto-ranging creates identical (same source and destination), sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.

Step 7 Click Next.

Step 8 Define the circuit attributes (Figure 6-3):

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—Choose VC12.

Bidirectional—Leave checked for this circuit (default).

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.

Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.

Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.

Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task.

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Apply to drop ports—Check this check box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.


Note If ports managed into the Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to Unlocked-disabled,failed.


Protected Drops—Check this check box if you want the circuit routed on protected drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you check this check box, CTC shows only protected cards and ports as source and destination choices.

Figure 6-3 Setting Circuit Attributes for a Low-Order VC12 Circuit

Step 9 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task. Otherwise, continue with Step 10.

Step 10 Click Next.

Step 11 Complete the "DLP-D95 Provision a Low-Order VC12 Circuit Source and Destination" task.

Step 12 In the Circuit Routing Preferences area (Figure 6-4), choose Route Automatically. Two options are available; choose either, both, or none based on your preferences.

Using Required Nodes/Spans—Check this check box if you want to specify nodes and spans to include or exclude in the CTC-generated circuit route.

Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.

Review Route Before Creation—Check this check box if you want to review and edit the circuit route before the circuit is created.

Figure 6-4 Setting Circuit Routing Preferences

Step 13 Set the circuit path protection:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.

To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.

To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 16.


Caution Circuits routed on MS-SPRing protection channels are not protected. They are preempted during MS-SPRing switches.

Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within SNCP ring portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not check for node diversity.

Step 15 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP DRI, check the Dual Ring Interconnect check box.

Step 16 If you selected Using Required Nodes/Spans in Step 12, complete the following substeps. If not, continue with Step 18.

a. Click Next.

b. In the Circuit Route Constraints For Auto Routing area, click a node or span on the circuit map.

c. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit will be routed. Click spans twice to change the circuit direction.

d. Repeat Step c for each node or span that you wish to include or exclude.

e. Review the circuit route. To change the circuit routing order, choose a node from the Required Nodes/Lines or Excluded Nodes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.

Step 17 Click Next. In the VC LO Matrix Optimization page, choose one of the following:

Create VC LO tunnel on transit nodes—This option is available if the VC12 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC12 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.

Create VC LO aggregation point—This option is available if you are creating a VC12 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 network, choose one of the following:

VC4 grooming node is source-node, VC12 grooming node is destination-node—Creates the LAP on the VC12 circuit source node. This option is available only if the VC12 circuit originates on an STM-N card.

VC4 grooming node is destination-node, VC12 grooming node is source-node—Creates the LAP on the VC12 circuit destination node. This option is available only if the VC12 circuit terminates on an STM-N card.

None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.

Step 18 If you selected Review Route Before Creation in Step 12, complete the following substeps. If not, continue with Step 19.

a. Click Next.

b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.

c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "NTP-D82 Create a Manually Routed Low-Order VC12 Circuit" procedure.

Step 19 Click Finish. One of the following results occurs, depending on the circuit properties you chose in the Circuit Creation dialog box:

If you entered more than 1 in the Number of Circuits field and selected Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.

If you entered more than 1 in the Number of Circuits field and did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 6 through 18 for each additional circuit. After completing the circuits, the Circuits window appears.

Step 20 In the Circuits window, verify that the new circuits appear in the circuits list.

Step 21 Complete the "NTP-D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.

Stop. You have completed this procedure.


NTP-D82 Create a Manually Routed Low-Order VC12 Circuit

Purpose

This procedure creates low-order VC12 circuit and allows you to provision the circuit route.

Tools/Equipment

XC-VXC-10G, XC-VXL-10G, or XC-VXL-2.5G cards must be installed at the circuit source and destination nodes.

Prerequisite Procedures

D127 Verify Network Turn-Up

Security Level

Provisioning or higher



Step 1 Complete the "DLP-D60 Log into CTC" task at an ONS 15454 SDH on the network where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2 Complete the following:

a. On the shelf graphic, verify that XC-VXC-10G, XC-VXL-10G, or XC-VXL-2.5G cross-connect cards are installed in Slots 8 and 10.

b. Click the Provisioning > Cross-Connect tabs and set the Low Order Payload Type to VC-12 or VC-11 and VC-12 (Mixed Mode).

Step 3 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-D314 Assign a Name to a Port" task. If you want CTC to assign a name automatically based on circuit type, node name, and sequence number, continue with Step 4.

Step 4 From the View menu, choose Go to Network View.

Step 5 Click the Circuits tab, then click Create.

Step 6 In the Circuit Creation dialog box, complete the following fields:

Circuit Type—Choose VC_LO_PATH_CIRCUIT.

Number of Circuits—Enter the number of VC12 circuits that you want to create. The default is 1. If you are creating multiple circuits with the same slot and consecutive port numbers, you can use Auto-ranged to create the circuits automatically.

Auto-ranged—This check box is automatically checked if you enter more than 1 in the Number of Circuits field. Auto-ranging creates identical (same source and destination), sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.

Step 7 Click Next.

Step 8 Define the circuit attributes (Figure 6-1):

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—Choose VC12.

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.

Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.

Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.

Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task.

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Apply to drop ports—Select this check box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.


Note If ports managed into the Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to Unlocked-disabled,failed.


Protected Drops—Check this check box if you want the circuit routed on protected drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you check this check box, CTC shows only protected cards and ports as source and destination choices.

Step 9 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task. Otherwise, continue with Step 10.

Step 10 Click Next.

Step 11 Complete the "DLP-D95 Provision a Low-Order VC12 Circuit Source and Destination" task.

Step 12 In the Circuit Routing Preferences area (Figure 6-2), uncheck Route Automatically. When Route Automatically is not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes are unavailable.

Step 13 Set the circuit path protection:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.

To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 17.

To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 17.


Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.

Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP, choose a Node-Diverse Path option:

Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired— Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not check for node diversity.

Step 15 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.

Step 16 Click Next. In the VC LO Matrix Optimization page, choose one of the following:

Create VC LO tunnel on transit nodes—This option is available if the VC12 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC12 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.

Create VC LO aggregation point—This option is available if you are creating a VC12 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto a VC4 for transport outside the ONS 15454 SDH network, choose one of the following:

VC4 grooming node is source-node, VC12 grooming node is destination-node—Creates the LAP on the VC12 circuit source node. This option is available only if the VC12 circuit originates on an STM-N card.

VC4 grooming node is destination-node, VC12 grooming node is source-node—Creates the LAP on the VC12 circuit destination node. This option is available only if the VC12 circuit terminates on an STM-N card.

None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.

Step 17 Click Next. In the Route Review/Edit area, node icons appear for circuit routing. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.

Step 18 Complete the "DLP-D3 Provision a Low-Order VC12 Circuit Route" task for the VC12 circuit you are creating.

Step 19 Click Finish. CTC compares your manually provisioned circuit route with the specified path diversity option you chose in Step 14. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path.

Step 20 If you entered more than 1 in the Number of Circuits field, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 6 through 19 for each additional circuit.

Step 21 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created are correct.

Step 22 Complete the "NTP-D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.

Stop. You have completed this procedure.

Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task.

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.


Note If ports managed into the Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to Unlocked-disabled,failed.


Protected Drops—Check this box if you want the circuit routed to protect drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you check this box, CTC displays only protected cards as source and destination choices.

Step 9 Click Next.

Step 10 Complete the "DLP-D95 Provision a Low-Order VC12 Circuit Source and Destination" task.

Step 11 In the Circuit Routing Preferences area, uncheck Route Automatically. When Route Automatically is not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes are unavailable.

Step 12 Set the circuit path protection:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.

To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.

To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 16.


Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.

Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on an SNCP, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not check for node diversity.

Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.

Step 15 Click Next. In the VC LO Matrix Optimization page, choose one of the following:

Create VC LO tunnel on transit nodes—This option is available if the VC12 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC12 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.

Create VC LO aggregation point—This option is available if you are creating a VC12 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 SDH network, choose one of the following:

VC4 grooming node is source-node, VC12 grooming node is destination-node—Creates the LAP on the VC12 circuit source node. This option is available only if the VC12 circuit originates on an STM-N card.

VC4 grooming node is destination-node, VC12 grooming node is source-node—Creates the LAP on the VC12 circuit destination node. This option is available only if the VC12 circuit terminates on an STM-N card.

None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.

Step 16 Click Next. In the Route Review and Edit area, node icons appear so you can route the circuit manually. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.

Step 7 Click Next.

Step 8 Define the circuit attributes (Figure 6-5):

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Auto-ranged—This check box is automatically selected if you enter more than 1 in the Number of Circuits field. Auto-ranging creates identical (same source and destination), sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.

Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.

Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.

Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task.

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Apply to drop ports—Check this check box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.


Note If ports managed into the Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to Unlocked-disabled,failed.


Protected Drops—Select this check box if you want the circuit routed on protected drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you select this check box, CTC displays only protected cards and ports as source and destination choices.

Figure 6-5 Setting Circuit Attributes For a Low-Order VC3 Circuit

Step 9 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task. Otherwise, continue with Step 10.

Step 10 Click Next.

Step 11 Complete the "DLP-D318 Provision a Low-Order VC3 Circuit Source and Destination" task.

Step 12 In the Circuit Routing Preferences area (Figure 6-2), choose Route Automatically. Two options are available; choose either, both, or none based on your preferences.

Using Required Nodes/Spans—Check this check box if you want to specify nodes and spans to include or exclude in the CTC-generated circuit route.

Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.

Review Route Before Creation—Check this check box if you want to review and edit the circuit route before the circuit is created.

Step 13 Set the circuit path protection:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.

To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 16.

To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, and then continue with Step 16.


Caution Circuits routed on MS-SPRing protection channels are not protected. They are preempted during MS-SPRing switches.

Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within SNCP ring portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not check for node diversity.

Step 15 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.

Step 16 If you selected Using Required Nodes/Spans in Step 12, complete the following substeps. If not, continue with Step 18.

a. Click Next.

b. In the Circuit Route Constraints For Auto Routing area, click a node or span on the circuit map.

c. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.

d. Repeat Step c for each node or span that you wish to include or exclude.

e. Review the circuit route. To change the circuit routing order, choose a node from the Required Nodes/Lines or Excluded Nodes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.

Step 17 Click Next. In the VC LO Matrix Optimization page, choose one of the following:

Create VC LO tunnel on transit nodes—This option is available if the VC3 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC3 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.

Create VC LO aggregation point—This option is available if you are creating a VC3 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 SDH network, choose one of the following:

VC4 grooming node is source-node, VC12 grooming node is destination-node—Creates the LAP on the VC3 circuit source node. This option is available only if the VC3 circuit originates on an STM-N card.

VC4 grooming node is destination-node, VC12 grooming node is source-node—Creates the LAP on the VC12 circuit destination node. This option is available only if the VC3 circuit terminates on an STM-N card.

None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.

Step 18 If you selected Review Route Before Creation in Step 12, complete the following substeps. If not, continue with Step 19.

a. Click Next.

b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.

c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "NTP-D55 Create a Manually Routed Low-Order VC3 Circuit" procedure.

Step 19 Click Finish. One of the following results occurs, depending on the circuit properties you chose in the Circuit Creation dialog box:

If you entered more than 1 in the Number of Circuits field and selected Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.

If you entered more than 1 in the Number of Circuits field and did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 6 through 18 for each additional circuit. After completing the circuits, the Circuits window appears.

Step 20 In the Circuits window, verify that the new circuits appear in the circuits list.

Step 21 Complete the "NTP-D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.

Stop. You have completed this procedure.

Step 1 Complete the "DLP-D60 Log into CTC" task at an ONS 15454 SDH on the network where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2 On the shelf graphic, verify that XC-VXL-10G or XC-VXL-2.5G cross-connect cards are installed in Slots 8 and 10.

Step 3 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-D314 Assign a Name to a Port" task. If you want CTC to assign a name automatically based on circuit type, node name, and sequence number, continue with Step 4.

Step 4 From the View menu, choose Go to Network View.

Step 5 Click the Circuits tab, then click Create.

Step 6 In the Circuit Creation dialog box, complete the following fields:

Circuit Type—Choose VC_LO_PATH_CIRCUIT.

Number of Circuits—Enter the number of VC3 circuits that you want to create. The default is 1. If you are creating multiple circuits with the same slot and consecutive port numbers, you can use Auto-ranged to create the circuits automatically.

Auto-ranged—This check box is automatically selected if you enter more than 1 in the Number of Circuits field. Auto-ranging creates identical (same source and destination), sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.

Step 7 Click Next.

Step 8 Define the circuit attributes (Figure 6-5):

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—Choose VC3.

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.

Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.

Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.

Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task.

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Apply to drop ports—Select this check box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.


Note If ports managed into the Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to Unlocked-disabled,failed.


Protected Drops—Select this check box if you want the circuit routed on protected drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you select this check box, CTC displays only protected cards and ports as source and destination choices.

Step 9 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task. Otherwise, continue with Step 10.

Step 10 Click Next.

Step 11 Complete the "DLP-D318 Provision a Low-Order VC3 Circuit Source and Destination" task.

Step 12 In the Circuit Routing Preferences area (Figure 6-2), uncheck Route Automatically.

Step 13 Set the circuit path protection:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.

To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 17.

To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 17.


Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.

Step 14 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP, choose a Node-Diverse Path option:

Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired— Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not check for node diversity.

Step 15 If you selected Fully Protected Path in Step 13 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.

Step 16 Click Next. In the VC LO Matrix Optimization page, choose one of the following:

Create VC LO tunnel on transit nodes—This option is available if the VC3 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC3 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.

Create VC LO aggregation point—This option is available if you are creating a VC3 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 SDH network, choose one of the following:

VC4 grooming node is source-node, VC12 grooming node is destination-node—Creates the LAP on the VC3 circuit source node. This option is available only if the VC3 circuit originates on an STM-N card.

VC4 grooming node is destination-node, VC3 grooming node is source-node—Creates the LAP on the VC3 circuit destination node. This option is available only if the VC3 circuit terminates on an STM-N card.

None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.

Step 17 Click Next. In the Route Review and Edit area, node icons appear for you to route the circuit. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.

Step 18 Complete the "DLP-D96 Provision a Low-Order VC3 Circuit Route" task for the VC3 circuit you are creating.

Step 19 Click Finish. CTC compares your manually provisioned circuit route with the specified path diversity option you chose in Step 14. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path.

Step 20 If you entered more than 1 in the Number of Circuits field, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 6 through 19 for each additional circuit.

Step 21 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created are correct.

Step 22 Complete the "NTP-D135 Test Low-Order Circuits" procedure. Skip this step if you built a test circuit.

Stop. You have completed this procedure.

Caution Circuits routed on MS-SPRing protection channels are not protected and are preempted during MS-SPRing switches.

Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on an SNCP, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not check for node diversity.

Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.

Step 15 Click Next. In the VC LO Matrix Optimization page, choose one of the following:

Create VC LO tunnel on transit nodes—This option is available if the VC3 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC3 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.

Create VC LO aggregation point—This option is available if you are creating a VC3 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix. If you want to aggregate the low-order circuit you are creating with others onto an VC4 for transport outside the ONS 15454 SDH network, choose one of the following:

VC4 grooming node is source-node, VC12 grooming node is destination-node—Creates the LAP on the VC3 circuit source node. This option is available only if the VC3 circuit originates on an STM-N card.

VC4 grooming node is destination-node, VC12 grooming node is source-node—Creates the LAP on the VC3 circuit destination node. This option is available only if the VC3 circuit terminates on an STM-N card.

None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.

Step 16 Click Next. In the Route Review and Edit area, node icons appear so you can route the circuit manually. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.

NTP-D187 Create a Low-Order Aggregation Point

Purpose

This procedure creates a low-order aggregation point (LAP). LAPs allow multiple VC3 or VC12 low-order circuits to be aggregated on a single VC4 circuit. LAPs allow multiple low-order circuits to pass through cross-connect cards without utilizing resources on the cross-connect card low-order matrix.

Note This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the "Network Element Defaults" appendix in the Cisco ONS 15454 SDH Reference Manual.



Note You can create low-order aggregation points for circuits in MS-SPRing or 1+1 protection, or for unprotected circuits. You cannot create them for SNCP ring circuits.



Note The maximum number of LAPs that you can create depends on the node protection topology and the number of low-order circuits that terminate on the node. Assuming that no other low-order circuits terminate at the node, the maximum number of LAPs that you can terminate at one node is 8 for 1+1 and 12 for MS-SPRing protection.



Step 1 Complete the "DLP-D60 Log into CTC" task at an ONS 15454 SDH on the network where you will create the LAP. If you are already logged in, continue with Step 2.

Step 2 If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the "DLP-D314 Assign a Name to a Port" task. If you want CTC to assign a name automatically based on circuit type, node name, and sequence number, continue with Step 3.

Step 3 From the View menu, choose Go to Network View.

Step 4 Click the Circuits tab, then click Create.

Step 5 In the Circuit Creation dialog box, choose VC_LO_PATH_AGGREGATION.

Size—Defaults to VC4. You cannot change the value.

Bidirectional—Defaults to Bidirectional. You cannot change the value.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.

Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.

Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.

Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task.

Step 6 From the View menu, choose Go to Network View.

Step 7 Click the Circuits tab, then click Create.

Step 8 In the Circuit Creation dialog box, complete the following fields:

Circuit Type—Choose VC_HO_PATH_CIRCUIT.

Number of Circuits—Enter the number of high-order circuits that you want to create. The default  is 1. If you are creating multiple circuits with the same source and destination, you can use auto-ranging to create the circuits automatically.

Auto-ranged—This check box is automatically selected when you enter more than 1 in the Number of Circuits field. Leave this check box selected if you are creating multiple high-order circuits with the same source and destination and you want CTC to create the circuits automatically. Uncheck the box if you do not want CTC to create the circuits automatically.

Step 9 Click Next.

Step 10 Define the circuit attributes (Figure 6-9):

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—Choose the high-order circuit size: VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, VC4-9c, VC4-16c, or VC4-64c. Valid circuit sizes for a G-Series or CE-MR-10 circuit are VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, and VC4-16c.

Bidirectional—Leave checked for this circuit (default).

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.

Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.

Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.

Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task.

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.


Note If ports managed into the Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to Unlocked-disabled,failed.


Protected Drops—Select this check box if you want the circuit routed to protected drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you select this check box, CTC shows only protected cards as source and destination choices.

Figure 6-9 Setting Circuit Attributes for an High-Order Circuit

Step 11 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task.

Step 12 Click Next.

Step 13 Complete the "DLP-D97 Provision a High-Order Circuit Source and Destination" task for the high-order circuit you are creating.

Step 14 In the Circuit Routing Preferences area, choose Route Automatically. Two options are available; choose either, both, or none based on your preferences.

Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.

Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.

Review Route Before Creation—Check this check box to review and edit the circuit route before the circuit is created.

Step 15 Set the circuit path protection:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 16. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments (with primary and alternate paths), and the path diversity options apply only to SNCP path segments, if any exist.

To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 18.

To route the circuit on an MS-SPRing protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 18.

Step 16 If you selected Fully Protected Path in Step 15 and the circuit will be routed on SNCP, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within SNCP ring portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not check for node diversity.

Step 17 If you selected Fully Protected Path in Step 15 and the circuit will be routed on an MS-SPRing DRI or SNCP DRI, check the Dual Ring Interconnect check box. If not, continue with Step 20.

Step 18 If you checked Dual Ring Interconnect for an SNCP in Step 17, complete the following substeps. If you checked Dual Ring Interconnect for a MS-SPRing, skip this step and continue with Step 19.

a. Click Next.

b. In the Circuit Route Constraints For Auto Routing area, click a node or span on the circuit map.

c. Click Include to include the node or span in the circuit, or click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.

d. Repeat Step c for each node or span that you wish to include or exclude.

e. Review the circuit route. To change the circuit routing order, choose a node from the Required Nodes/Lines or Excluded Nodes Links lists, then click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.

Step 19 If you checked Dual Ring Interconnect for a MS-SPRing in Step 17, complete the following substeps to assign primary and secondary nodes and ring type.

a. In the Circuit Constraints for Automatic Routing area, click Add MS-SPRing DRI.

b. In the confirmation window, click OK.

c. In the Node Options area of the MS-SPRing DRI Options dialog box, complete the following:

Primary Node—For a traditional or integrated MS-SPRing DRI, choose the node where the circuit interconnects the rings.

Secondary Node—For a traditional or integrated MS-SPRing DRI, choose the secondary node for the circuit to interconnect the rings. This route is used if the route on the primary node fails.

Primary Node #2—For a traditional MS-SPRing DRI where two primary nodes are required to interconnect rings, choose the second primary node.

Secondary Node #2—For a traditional MS-SPRing DRI where two secondary nodes are required, choose the second secondary node.

d. In the Ring and Path Options area, complete the following:

The first ring is—Choose SNCP or MS-SPRing from the drop-down list.

The second ring is—Choose SNCP or MS-SPRing from the drop-down list.

Use ring interworking protection (RIP) on secondary path—Check this box to carry the secondary spans on the protection channels. These spans will be preempted during a ring/span switch.

e. Click OK. The node information appears in the Required Nodes/Lines list, and the map graphic indicates which nodes are primary and secondary.

f. In the Circuit Constraints for Automatic Routing area, click a node or span on the circuit map.

g. Click Include to include the node or span in the circuit, or click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit will be routed. Click spans twice to change the circuit direction. If you are creating an SNCP to MS-SPRing traditional handoff, exclude the unprotected links from the primary node towards the secondary node. If you are creating an SNCP to MS-SPRing integrated handoff, exclude unnecessary DRIs on the SNCP segments.

h. Review the circuit constraints. To change the circuit routing order, choose a node in the Required Nodes/Lines lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.

Step 20 If you selected Review Route Before Creation in Step 14, complete the following substeps; otherwise, continue with Step 22:

a. Click Next.

b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.

c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "NTP-D324 Create a Manually Routed High-Order Circuit" procedure to assign the circuit route yourself.

Step 21 If you selected Review Route Before Creation in Step 14, click Next. If not, continue with Step 22. View the route in the Route Review/Edit window. As necessary, click Add MS-SPRing DRI to add another DRI. Click Remove to remove a DRI assignment. Click the Included Spans tab to view the spans. The map graphic updates as you apply changes.

Step 22 Click Finish. One of the following occurs, based on the circuit properties that you provisioned in the Circuit Creation dialog box:

If you entered more than 1 in the Number of Circuits field and selected Auto-ranged, CTC automatically creates the number of circuits entered in Number of Circuits. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable on the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.

If you entered more than 1 in Number of Circuits and did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 8 through 21 for each additional circuit. After completing the circuits, the Circuits window appears.

Step 23 In the Circuits window, verify that the circuits you created appear in the circuits list.

Step 24 Complete the following as necessary. Skip this step if you built a test circuit.

a. Complete the "NTP-D62 Test High-Order Circuits" procedure.

b. Complete the "NTP-D149 Test G-Series Circuits" procedure.

Stop. You have completed this procedure.

Bidirectional—Leave checked for this circuit.

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.

Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state. Traffic is not passed on the circuit.

Unlocked,automaticInService—Puts the circuit cross-connects in the Unlocked-disabled,automaticInService service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to Unlocked-enabled.

Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the "DLP-D230 Change a Circuit State" task.

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.


Note If ports managed into the Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to Unlocked-disabled,failed.


Protected Drops—Select this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 SDH cards that are in 1:1, 1:N, or 1+1 protection. If you select this check box, CTC shows only protected cards as source and destination choices.

Step 1 Complete the "DLP-D60 Log into CTC" task at an ONS 15454 SDH on the network where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-D314 Assign a Name to a Port" task. If you want CTC to assign a name automatically based on circuit type, node name, and sequence number, continue with Step 3.

Step 3 If a high number of VLANs is already used by the network, complete the "DLP-D99 Determine Available VLANs" task to verify that sufficient VLAN capacity is available. (You will create a VLAN during each circuit creation task.)

Step 4 If enough VLANs are not available, complete the "DLP-D34 Delete VLANs" task to free space.

Step 5 Verify that the circuit source and destination Ethernet cards are provisioned for the mode of the circuit you will create, either multicard or single-card. See the "DLP-D246 Provision E-Series Ethernet Card Mode" task.

Step 6 From the View menu, choose Go to Network View.

Step 7 Click the Circuits tab, then click Create.

Step 8 In the Circuit Creation dialog box, complete the following fields:

Circuit Type—Choose VC_HO_PATH_CIRCUIT.

Number of Circuits—Leave the default unchanged (1).

Auto-ranged—Unavailable.

Step 9 Click Next.

Step 10 Define the circuit attributes:

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—Choose the circuit size. Valid circuit sizes for an Ethernet multicard circuit are VC4 and VC4-2c. Valid circuit sizes for an Ethernet single-card circuit are VC4, VC4-2c, and VC4-4c.

Bidirectional—Leave the default unchanged (checked).

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose IS. Ethergroup circuits are always in service.

Apply to drop ports—Uncheck this box.

Protected Drops—Leave the default unchanged (unchecked).

Step 11 If the circuit will be routed on an SNCP ring, complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task.


Caution Layer 1 SDH protection does not extend to multicard EtherSwitch circuits on SNCP rings.


Caution A TCC2/TCC2P card reset disrupts single-card and multicard Etherswitch circuits for 45 seconds to two minutes. During this time, a spanning tree topology is created by the newly activated TCC2/TCC2P card.

Step 12 Click Next.

Step 13 Provision the circuit source:

a. From the Node drop-down list, choose one of the EtherSwitch circuit endpoint nodes. (Either end node can be the EtherSwitch circuit source.)

b. From the Slot drop-down list, choose one of the following:

If you are building a multicard EtherSwitch circuit, choose Ethergroup.

If you are building a single-card EtherSwitch circuit, choose the Ethernet card where you enabled the single-card EtherSwitch.

Step 14 Click Next.

Step 15 Provision the circuit destination:

a. From the Node drop-down list, choose the second EtherSwitch circuit endpoint node.

b. From the Slot drop-down list, choose one of the following:

If you are building a multicard EtherSwitch circuit, choose Ethergroup.

If you are building a single-card EtherSwitch circuit, choose the Ethernet card where you enabled the single-card EtherSwitch.

Step 16 Click Next.

Step 17 In the Circuit VLAN Selection area, click New VLAN. If the VLAN already exists, continue with Step 20.


Tip You can also add VLANs in network view by choosing Tools > Manage VLANs. In the All VLANs dialog box, click the Create button to open the Define New VLAN dialog box.


Step 18 In the New VLAN dialog box, complete the following:

VLAN Name—Assign an easily identifiable name to your VLAN.

VLAN ID—Assign a VLAN ID. The VLAN ID should be the next available number between 2 and 4093 that is not already assigned to an existing VLAN. Each ONS 15454 SDH network supports a maximum of 509 user-provisionable VLANs.

Topology Host—Choose the topology host ID from the drop-down list.

Step 19 Click OK.

Step 20 In the Circuit VLAN Selection area, highlight the VLAN name and click the arrow button (>>) to move the available VLANs to the Circuit VLANs column.

Step 21 If you are building a single-card EtherSwitch circuit and want to disable spanning tree protection on this circuit, uncheck the Enable Spanning Tree check box and click OK on the Disabling Spanning Tree dialog box. The Enable Spanning Tree box remains checked or unchecked for the creation of the next single-card, point-to-point Ethernet circuit.


Caution Disabling spanning tree protection increases the likelihood of logic loops on an Ethernet network.


Caution Turning off spanning tree on a circuit-by-circuit basis means that the ONS 15454 SDH is no longer protecting the Ethernet circuit and that the circuit must be protected by another mechanism in the Ethernet network.


Caution Multiple circuits with spanning tree protection enabled incur blocking if the circuits traverse the same E-Series card and use the same VLAN.

Spanning tree rules prevent users from creating new circuits or modifying existing circuits if the circuits do not meet certain VLAN assignment constraints. If the VLAN set of the new circuit overlaps with existing circuits, the same spanning tree instance is used for all circuits. If the VLAN set of the new circuit overlaps with VLAN sets of existing circuits with different spanning tree instances, the VLAN assignment fails. Cisco recommends that you plan VLAN assignments so that circuits with larger VLAN sets and a higher chance of overlap are added first. This means that if a circuit with an overlapping VLAN set is added, it collapses into the same spanning tree. To view circuits mapped to a spanning tree and their VLAN assignments, see the "DLP-D23 View Spanning Tree Information" task.

You can disable or enable spanning tree protection on a circuit-by-circuit basis only for single-card, point-to-point Ethernet circuits. Other E-Series Ethernet configurations disable or enable spanning tree on a port-by-port basis.

Step 22 Click Next.

Step 23 Confirm that the following information about the circuit is correct:

Circuit name

Apply to drop ports—Select this check box if you want to apply the state chosen in the State field (Unlocked or Locked,maintenance only) to the Ethernet circuit source and destination ports. You cannot apply Unlocked,automaticInService to E-Series Ethernet card ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.


Note If ports managed into the Unlocked administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to Unlocked-disabled,failed.

Step 3 From the View menu, choose Go to Network View.

Step 4 Click the Circuits tab, then click Create.

Step 5 In the Circuit Creation dialog box, choose VC_HO_PATH_VCAT_CIRCUIT from the Circuit Type drop-down list.

Step 6 Click Next.

Step 7 Define the circuit attributes (Figure 6-13):

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Type—Displays the circuit type you chose in Step 5. You cannot change it.

Bidirectional—Checked is the default. You cannot change it.

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose Unlocked.

Apply to drop ports—Check this check box to apply the IS administrative state to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box shows the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not change the service state of the source and destination ports.

Symmetric—Checked is the default. You cannot change it.

Member size—Choose the member size. For information about the member size supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Num. of members—Choose the number of members. For information about the number of members supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.


Note When creating open-ended VCAT circuits the number of members must be the same on each side of the virtual concatenated group (VCG). The configuration with different number of members on each side of circuit is not supported. This is applicable to circuits created on CE-Series and ML-Series cards.


Mode—Choose the protection mode for the VCAT circuit:

None—Provides no protection. A failure on one member causes the entire VCAT circuit to fail. You cannot delete members after creating a VCAT circuit with no protection.

SW-LCAS—(Software link capacity adjustment scheme) Allows the VCAT circuit to adapt to member failures and keep traffic flowing after failures at a reduced bandwidth. SW-LCAS provides interoperability with the ML-Series cards. SW-LCAS uses legacy SONET failure indicators like path alarm indication signal (AIS-P) and path remote defect indication (RDI-P) to detect member failure. You cannot add or delete members from a VCAT circuit with SW-LCAS protection.


Note While deleting SW-LCAS circuit members change the administrative state of the members to Locked,disabled. This is applicable to circuits created on CE-Series and ML-Series cards.


LCAS—Sets the VCAT circuit to use LCAS. With LCAS, you can add or delete members without interrupting the operation of uninvolved members. If a member fails, LCAS temporarily removes the failed member from the VCAT circuit. The remaining members carry the traffic until the failure clears.


Note For CE-MR-10 card, before you create a VCAT circuit in the LCAS protection mode, it is recommended that you move all members of the VCAT circuit being created to Locked,OutOfGroup service state and then move them to Unlocked state.



Note While deleting HW-LCAS circuit members change the administrative state of the members to Locked, OutOfGroup. This is applicable to circuits created on CE-Series and ML-Series cards.

Step 9 Complete the "DLP-D36 Provision a VCAT Circuit Source and Destination" task for the VCAT circuit you are creating. If you are creating an open-ended VCAT circuit, complete the "DLP-D290 Provision an Open VCAT Circuit Source and Destination" task.

Step 10 In the VCAT Circuit Routing Preferences area (Figure 6-14), check Route Automatically. Two options are available; choose either, both, or none based on your preferences.

Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.

Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.

Review Route Before Creation—Check this check box to review and edit the circuit route before the circuit is created.

Step 11 If you want to set preferences for individual members, complete the following in the Member Preferences area. Repeat for each member and continue with Step 13. To set identical preferences for all members, skip this step and continue with Step 12.

a. Number—Choose a number (between 1 and 256) from the drop-down list to identify the member.

b. Name—Type a unique name to identify the member. The name can be alphanumeric and up to 48 characters (including spaces). If you leave the field blank, CTC assigns a default name to the circuit.

c. Protection—Choose the member protection type:

Fully Protected—Routes the circuit on a protected path.

Unprotected—Creates an unprotected circuit.

PCA—Routes the member on an MS-SPRing protection channel.

Step 12 To set preferences for all members, choose the member protection type:

Fully Protected—Routes the circuit on a protected path.

Unprotected—Creates an unprotected circuit.

Step 1 Complete the "DLP-D60 Log into CTC" task at the node where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2 If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the "DLP-D314 Assign a Name to a Port" task. If you want CTC to assign a name automatically based on circuit type, node name, and sequence number, continue with Step 6.

Step 3 Complete the following as necessary (you can provision Ethernet or POS ports before or after the VCAT circuit is created):

To provision Ethernet ports for CE-100T-8 or CE-MR-10 circuits, complete the "DLP-D136 Provision CE-100T-8 and CE-MR-10 Ethernet Ports" task.

To provision Ethernet ports for CE-1000-4 circuits, complete the "DLP-D211 Provision CE-1000-4 Ethernet Ports" task.

To provision POS ports for CE-Series circuits, complete the "DLP-D141 Provision CE-100T-8, CE-1000-4, and CE-MR-10 POS Ports" task.

To provision Ethernet ports for ML-Series circuits, complete the "DLP-D493 Provision the Ethernet Port of the ML-Series Card" task.

To provision POS ports for ML-Series circuits, complete the "DLP-D494 Provision the POS Port of the ML-Series Card" task.

Step 4 From the View menu, choose Go to Network View.

Step 5 In the Circuit Creation dialog box, choose VC_HO_PATH_VCAT_CIRCUIT from the Circuit Type drop-down list.

Step 6 Click Next.

Step 7 Define the circuit attributes (Figure 6-13):

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Type—Displays the circuit type you chose in Step 5. You cannot change it.

Bidirectional—Checked is the default. You cannot change it.

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose Unlocked.

Apply to drop ports—Check this check box to apply the IS administrative state to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box shows the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not change the service state of the source and destination ports.

Symmetric—Checked is the default. You cannot change it.

Member size—Choose the member size. For information about the member size supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.

Num. of members—Choose the number of members. For information about the number of members supported for each card, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual.


Note When creating open-ended VCAT circuits the number of members must be the same on each side of the virtual concatenated group (VCG). The configuration with different number of members on each side of circuit is not supported. This is applicable to circuits created on CE-Series and ML-Series cards.


Mode—Choose the protection mode for the VCAT circuit:

None—Provides no protection. A failure on one member causes the entire VCAT circuit to fail. You cannot delete members after creating a VCAT circuit with no protection.

SW-LCAS—Allows the VCAT circuit to adapt to member failures and keep traffic flowing after failures at a reduced bandwidth. SW-LCAS provides interoperability with the ML-Series cards. SW-LCAS uses legacy SONET failure indicators like AIS-P and RDI-P to detect member failure. You cannot add or delete members from a VCAT circuit with SW-LCAS protection.


Note While deleting SW-LCAS circuit members change the administrative state of the members to Locked,disabled. This is applicable to circuits created on CE-Series and ML-Series cards.


LCAS—Sets the VCAT circuit to use LCAS. With LCAS, you can add or delete members without interrupting the operation of uninvolved members. If a member fails, LCAS temporarily removes the failed member from the VCAT circuit. The remaining members carry the traffic until the failure clears.


Note For CE-MR-10 card, before you create a VCAT circuit in the LCAS protection mode, it is recommended that you move all members of the VCAT circuit being created to Locked,OutOfGroup service state and then move them to Unlocked state.



Note While deleting HW-LCAS circuit members change the administrative state of the members to Locked, OutOfGroup. This is applicable to circuits created on CE-Series and ML-Series cards.


Step 8 Click Next.

Step 9 Complete the "DLP-D36 Provision a VCAT Circuit Source and Destination" task for the VCAT circuit you are creating. If you are creating an open-ended VCAT circuit, complete the "DLP-D290 Provision an Open VCAT Circuit Source and Destination" task.

Step 10 In the Circuit Routing Preferences area (Figure 6-14), uncheck Route Automatically.

Step 11 If you want to set preferences for individual members, complete the following in the Member Preferences area. Repeat for each member and continue with Step 13. To set identical preferences for all members, skip this step and continue with Step 12.

a. Number—Choose a number (between 1 and 256) from the drop-down list to identify the member.

b. Name—Type a unique name to identify the member. The name can be alphanumeric and up to 48 characters (including spaces). If you leave the field blank, CTC assigns a default name to the circuit.

c. Protection—Choose the member protection type:

Fully Protected—Routes the circuit on a protected path.

Unprotected—Creates an unprotected circuit.

PCA—Routes the member on a MS-SPRing protection channel.

Step 12 To set preferences for all members, choose the member protection type:

Fully Protected—Routes the circuit on a protected path.

Unprotected—Creates an unprotected circuit.

PCA—Routes the member on a MS-SPRing protection channel.

Step 13 Click Next. If you chose Fully Protected or PCA, click OK to continue. If not, continue with the next step.

Step 14 In the Route Review and Edit area, node icons appear so you can route the circuit manually.

Step 15 Complete the "DLP-D26 Provision a VCAT Circuit Route" task.
