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, dense wavelength division multiplexing (DWDM) optical channel network connections, 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 8-1 defines ONS 15454 SDH circuit creation terms and options.

Table 8-1 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, 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 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 VC12 circuit spans.

Low-order aggregation point

Low-order aggregation points (LAPs) allow low-order 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. 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 8-2 shows the circuit source and destination options for low-order circuits.

Provisioning or higher



Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 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 an IP address 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 6, "Turn Up 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 6, "Turn Up 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-D464 Provision SDH DCC Terminations" task on page 6-4.

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 on page 12-2.

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 on page 12-4.

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 on page 12-15.

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: span reversion and east/west protect card assignments

If you need to make corrections, see the "NTP-D40 Provision MS-SPRing Nodes" procedure on page 6-15 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 on page 4-4 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 on page 12-33 to correct the information.

h. Click the DCC/GCC/OSC 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 6, "Turn Up 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 on page 12-23 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 on page 9-17 to change the information.

k. Verify that the network element 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-D81 Create an Automatically Routed Low-Order VC12 Circuit

Purpose

This procedure creates an automatically routed low-order VC12 circuit, meaning CTC chooses the circuit route based on the parameters you specify and on the software version.

Tools/Equipment

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

Prerequisite Procedures

Onsite/Remote

Onsite or remote

Security Level

Provisioning or higher



Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 at an ONS 15454 SDH on the network where you will create 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 not, 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—Type the number of DS-1 circuits 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:

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).

State—Choose a service state to apply to the circuit:

IS—The circuit is in service.

OOS—The circuit is out of service. Traffic is not passed on the circuit.

OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).

OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-13.


Note If low-order circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, low-order circuits in OOS_AINS change to IS even if a physical signal is not present. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.


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 Loss of signal alarms are generated if in service (IS) ports are not receiving signals.


Inter-domain (UCP) SLA—If the circuit will travel on a unified control plane (UCP) channel, enter the service level agreement (SLA) number. Otherwise, leave the field set to zero.

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 8-1), 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.

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

Figure 8-1 Setting Circuit Routing Preferences for a Low-Order VC12 Circuit

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 a 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 19.

a. Click Next.

b. In the Circuit Route Constraints 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 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 Notes 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 Circuit options panel, choose one of the following:

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. Low-order tunnels are required if the circuit passes through a node with XC10G cross-connect cards. In general, 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.

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 low-order aggregation point (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:

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

Circuit destination is VC4 grooming end—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 chose VC LO aggregation point, complete the following substeps. If not, continue with Step 19.

a. Click Next.

b. In the VC LO Aggregation Point Destination panel, click the node that you want to be the LAP destination, then click Add Destination.

Step 19 If you selected Review Route Before Creation in Step 12, complete the following substeps. If not, continue with Step 20.

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 "D82 Create a Manually Routed Low-Order VC12 Circuit" procedure.

Step 20 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 circuit(s), 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 20 for each additional circuit. After completing the circuit(s), the Circuits window appears.

Step 21 In the Circuits window, verify that the new circuit(s) appear in the circuits list.

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

Stop. You have completed this procedure.

Step 1 In the SNCP area of the Circuit Attributes panel, set the SNCP path selectors:

Provision working go and return on primary path—Check this box to route the working path on one fiber pair and the protect path on a separate fiber pair. This feature only applies to bidirectional SNCP circuits.

Revertive—Check this box if you want traffic to revert to the working path when the conditions that diverted it to the protect path are repaired. If you do not choose Revertive, traffic remains on the protect path after the switch.

Reversion time—If Revertive is checked, click the Reversion time field and choose a reversion time from the drop-down menu. The range is 0.5 to 12.0 minutes. The default is 5.0 minutes. This is the amount of time that will elapse before the traffic reverts to the working path. Traffic can revert when conditions causing the switch are cleared.

SF threshold—For high-order circuits, set the SNCP path-level signal failure bit error rate (BER) thresholds. Unavailable for low-order circuits.

SD threshold—For high-order circuits, set the SNCP path-level signal degrade BER thresholds. Unavailable for low-order circuits.

Switch on PDI-P—For high-order circuits, check this box if you want traffic to switch when an high-order payload defect indicator is received. Unavailable for low-order circuits.

Figure 8-3 Defining the Circuit Source on a E1-42 Card

Step 3 Choose the port from the Port drop-down menu.

Step 4 Only if you choose the E1_42 card, choose the source TUG3 from the TUG3 drop-down menu.

Step 5 From the TUG2 drop-down menu, choose the source TUG2.

Step 6 From the VC12 drop-down menu, choose the source VC12.

Step 7 If you need to create a secondary source, for example, an SNCP ring bridge/selector circuit entry point in a multivendor SNCP ring, click Use Secondary Source and repeat Steps 1 through 6 to define the secondary source. If you do not need to create a secondary source, continue with Step 8.

Step 8 Click Next.

Step 9 From the Node drop-down menu, choose the destination (termination) node.

Step 10 From the Slot drop-down menu, choose the slot containing the destination card. The destination is typically a E1 card. However, you can also choose an STM-N card to map the VC12 to a VC4 for optical transport.

Step 11 Depending on the destination card, choose the destination port from the drop-down menus that appear based on the card selected in Step 10. See Table 8-2 for a list of valid options. CTC does not show ports, VC4s, TUG3s, TUG2s, or VC12s already used by other circuits. If you and a user working on the same network choose the same VC4, TUG3, TUG2, or VC12 simultaneously, one of you receives a Path in Use error and is unable to complete the circuit. The user with the incomplete circuit needs to choose new destination parameters.

Step 12 If you need to create a secondary destination, for example, an SNCP ring bridge/selector circuit exit point in a multivendor SNCP ring, click Use Secondary Destination and repeat Steps 9 through 11 to define the secondary destination.

Step 13 Click Next.

Step 14 Return to your originating procedure (NTP).

Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 at an ONS 15454 SDH on the network where you will create 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 not, 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—Type the number of VC12 circuits 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:

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.

State—Choose a service state to apply to the circuit:

IS—The circuit is in service.

OOS—The circuit is out of service. Traffic is not passed on the circuit.

OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).

OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-13.


Note If low-order circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, low-order circuits in OOS_AINS change to IS even if a physical signal is not present. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.


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 Loss of signal alarms are generated if in service (IS) ports are not receiving signals.


Inter-domain (UCP) SLA—If the circuit will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.

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 8-1), 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 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, and then continue with Step 18.


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 a 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 Circuit Options panel, choose one of the following:

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. Low-order tunnels are required if the circuit passes through a node with XC10G cross-connect cards. In general, 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.

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 low-order aggregation point (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:

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

Circuit destination is VC4 grooming end—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 If you chose VC LO aggregation point, complete the following substeps. If not, continue with Step 18.

a. Click Next.

b. In the VC LO Aggregation Point Destination panel, click the node that you want to be the LAP destination, then click Add Destination.

Step 18 Click Next. In the Route Review and 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 19 Complete the "DLP-D96 Provision a Low-Order VC3 Circuit Route" task for the VC12 circuit you are creating.

Step 20 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. 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 20 for each additional circuit.

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

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

Stop. You have completed this procedure.

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 8-5), 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.

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

Figure 8-5 Setting Circuit Routing Preferences for a Low-Order VC3 Circuit

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 a 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 19.

a. Click Next.

b. In the Circuit Route Constraints 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 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 Notes 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 Circuit Options panel, choose one of the following:

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. Low-order tunnels are required if the circuit passes through a node with XC10G cross-connect cards. In general, 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.

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 low-order aggregation point (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:

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

Circuit destination is VC4 grooming end—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 18 If you chose VC LO aggregation point, complete the following substeps. If not, continue with Step 19.

a. Click Next.

b. In the VC LO Aggregation Point Destination panel, click the node that you want to be the LAP destination, then click Add Destination.

Step 19 If you selected Review Route Before Creation in Step 12, complete the following substeps. If not, continue with Step 20.

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 "D82 Create a Manually Routed Low-Order VC12 Circuit" procedure.

Step 20 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 circuit(s), 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 20 for each additional circuit. After completing the circuit(s), the Circuits window appears.

Step 21 In the Circuits window, verify that the new circuit(s) appear in the circuits list.

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

Stop. You have completed this procedure.

Note After you have selected the circuit properties in the Circuit Source dialog box according to the specific circuit creation procedure, you are ready to provision the circuit source.



Step 1 From the Node drop-down menu, choose the node where the source will originate.

Step 2 From the Slot drop-down menu, choose the slot containing the E3-12 or DS3i-N-12 card where the circuit will originate. You can also choose an STM-N card to map the VC3 to a VC4 for optical transport Figure 8-6 shows an example circuit source for an E3-12 card.

Figure 8-6 Defining the Circuit Source on a E3-12 Card

Step 3 Choose the port from the Port drop-down menu.

Step 4 Choose the VC4 from the VC4 drop-down menu.

Step 5 Choose the VC3 from the VC3 drop-down menu.

Step 6 If you need to create a secondary source, for example, an SNCP ring bridge/selector circuit entry point in a multivendor SNCP ring, click Use Secondary Source and repeat Steps 1 through 5 to define the secondary source. If you do not need to create a secondary source, continue with Step 8.

Step 7 Click Next.

Step 8 From the Node drop-down menu, choose the destination (termination) node.

Step 9 From the Slot drop-down menu, choose the slot containing the destination card. The destination is typically a E3 or DS3 card. However, you can also choose an STM-N card to map the VC3 to a VC4 for optical transport.

Step 10 Depending on the destination card, choose the destination port from the drop-down menus that appear based on the card selected in Step 2. See Table 8-2 for a list of valid options. CTC does not show ports, VC4s, or VC3s already used by other circuits. If you and a user working on the same network choose the same port, VC4, or VC3 simultaneously, one of you receives a Path in Use error and is unable to complete the circuit. The user with the incomplete circuit needs to choose new destination parameters.

Step 11 If you need to create a secondary destination, for example, an SNCP ring bridge/selector circuit exit point in a multivendor SNCP ring, click Use Secondary Destination and repeat Steps 8 through 10 to define the secondary destination.

Step 12 Click Next.

Step 13 Return to your originating procedure (NTP).

Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 at an ONS 15454 SDH on the network where you will create 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 not, 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—Type the number of VC3 circuits 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 8-4):

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.

State—Choose a service state to apply to the circuit:

IS—The circuit is in service.

OOS—The circuit is out of service. Traffic is not passed on the circuit.

OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).

OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-13.


Note If low-order circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, low-order circuits in OOS_AINS change to IS even if a physical signal is not present. Refer to the Cisco ONS 15454 SDH Reference Manual for more information.


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 Loss of signal alarms are generated if in service (IS) ports are not receiving signals.


Inter-domain (UCP) SLA—If the circuit will travel on a unified control plane (UCP) channel, enter the service level agreement number. Otherwise, leave the field set to zero.

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 8-1), 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 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.


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 a 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 Circuit Options panel, choose one of the following:

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. Low-order tunnels are required if the circuit passes through a node with XC10G cross-connect cards. In general, 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.

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 low-order aggregation point (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:

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

Circuit destination is VC4 grooming end—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 If you chose VC LO aggregation point in Step 16, complete the following substeps. If not, continue with Step 18.

a. Click Next.

b. In the Select Low-Order Grooming Node area, click the node that you want to be the LAP grooming node, then click Add Destination.

Step 18 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 19 Complete the "DLP-D96 Provision a Low-Order VC3 Circuit Route" task for the VC3 circuit you are creating.

Step 20 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. 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 20 for each additional circuit.

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

Note Low-order tunnels allow low-order VC12 and VC3 circuits to pass through intermediary ONS 15454 SDH nodes without consuming low-order matrix resources on the cross-connect card. In general, creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Low-order tunnels are required if low-order circuits must pass through nodes with XC10G cross-connect cards. Refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual for more information.



Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 at an ONS 15454 SDH on the network where you will create circuit. If you are already logged in, continue with Step 2.

State—Choose a service state to apply to the low-order tunnel:

IS—The low-order tunnel is in service.

OOS—The low-order tunnel is out of service. Traffic is not passed on the circuit.

OOS-AINS—The low-order tunnel is in service when it receives a valid signal; until then, the tunnel is out of service.

OOS-MT—The low-order tunnel is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the tunnel. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-13.

Note Low-order tunnels allow low-order circuits to pass through intermediary ONS 15454 SDHs without consuming low-order matrix resources on the cross-connect card. In general, 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 "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH Reference Manual for more information.



Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 at an ONS 15454 SDH on the network where you will create 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 not, continue with Step 4.

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, complete the following fields:

Circuit Type—Choose VC_LO_PATH TUNNEL.

For VC3 Port Grouping Only—Leave this box unchecked.

Step 6 Click Next.

Step 7 Define the circuit attributes (Figure 8-9):

Name—Assign a name to the low-order tunnel. 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 tunnel.

Size—The default size is VC4. You cannot change this value.

Bidirectional—Unavailable for low-order tunnels.

State—Choose a service state to apply to the low-order tunnel:

IS—The low-order tunnel is in service.

OOS—The low-order tunnel is out of service. Traffic is not passed on the circuit.

OOS-AINS—The low-order tunnel is in service when it receives a valid signal; until then, the circuit is out of service.

OOS-MT—The low-order tunnel is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed. Use OOS-MT for testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-13.

Apply to drop ports—Unavailable for low-order tunnels.

Inter-domain (UCP) SLA—If the tunnel will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.

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

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

State—Choose a service state to apply to the LAP:

IS—The LAP is in service.

OOS—The LAP is out of service. Traffic is not passed on the circuit.

OOS-AINS—The LAP is in service when it receives a valid signal; until then, the tunnel is out of service.

OOS-MT—The LAP is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the LAP. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-13.

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, complete the following fields:

Circuit Type—Choose VC_HO_PATH_CIRCUIT.

Number of Circuits—Type the number of high-order circuits 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 6 Click Next.

Step 7 Define the circuit attributes (Figure 8-10):

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.

Bidirectional—Leave checked for this circuit (default).

State—Choose a service state to apply to the circuit:

IS—The circuit is in service.

OOS—The circuit is out of service. Traffic is not passed on the circuit.

OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).

OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-13.

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 Loss of signal alarms appear if in service (IS) ports are not receiving signals.


Inter-domain (UCP) SLA—If the circuit will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.

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.

Step 9 Click Next.

Step 10 Complete the "DLP-D97 Provision a High-Order Circuit Source and Destination" task for the high-order circuit you are creating.

Step 11 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—Choose this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.

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

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. 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 15.

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 15.

Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a 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 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 If you selected Using Required Nodes/Spans in Step 11, complete the following substeps. If not, continue with Step 16:

Step 1 From the Node drop-down menu, choose the node where the circuit will originate.

Step 2 From the Slot drop-down menu, choose the slot containing the high-order card where the circuit originates. (If a card's capacity is fully utilized, it does not appear in the menu.)

Step 3 Depending on the circuit origination card, choose the source port and/or VC-4 from the Port and VC-4 drop-down menus. The Port menu is only available if the card has multiple ports. VC-4s are not shown if they are already in use by other circuits.


Note The VC4s that appear depend on the card, circuit size, and protection scheme. For example, if you create an VC4 circuit on an STM-4 card in an SNCP ring, only four VC4s are available. If you create an VC4 circuit on an STM-4 card in an MS-SPRing, two VC4s are available because of the MS-SPRing protection characteristics.


Step 4 If you need to create a secondary source, for example, an SNCP ring bridge/selector circuit entry point in a multivendor SNCP ring, click Use Secondary Source and repeat Steps 1 through 3 to define the secondary source.

Step 5 Click Next.

Step 6 From the Node drop-down menu, choose the destination node.

Step 7 From the Slot drop-down menu, choose the slot containing the optical card where the circuit will terminate (destination card). (If a card's capacity is fully utilized, the card does not appear in the menu.)

Step 8 Depending on the card selected in Step 2, choose the destination port and/or VC-4 from the Port and VC-4 drop-down menus. The Port menu is available only if the card has multiple ports. The VC-4s that appear depend on the card, circuit size, and protection scheme.

Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 at an ONS 15454 SDH on the network where you will create 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 not, continue with Step 3.

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

Step 4 In the Circuit Creation dialog box, complete the following fields:

Circuit Type—Choose VC_HO_PATH_CIRCUIT.

Number of Circuits—Type the number of high-order circuits you want to create. The default is 1.

Auto-ranged—Applies to automatically routed circuits only. If you entered more than 1 in Number of Circuits, uncheck this check box. (The check box is unavailable if only one circuit is entered in Number of Circuits.)

Step 5 Click Next.

Step 6 Define 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 high-order circuit size: VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, VC4-12c, VC4-16c, or VC4-64c.

Bidirectional—Leave checked for this circuit.

State—Choose a service state to apply to the circuit:

IS—The circuit is in service.

OOS—The circuit is out of service. Traffic is not passed on the circuit.

OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).

OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-13.

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 Loss of signal alarms appear if in service (IS) ports are not receiving signals.


Inter-domain (UCP) SLA—If the circuit will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.

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

Step 8 Click Next.

Step 9 Complete the "DLP-D97 Provision a High-Order Circuit Source and Destination" task for the high-order circuit you are creating.

Step 10 In the Circuit Routing Preferences area, uncheck Route Automatically.

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 12.

To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 14.

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 14.


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

Step 12 If you selected Fully Protected Path in Step 11 and the circuit will be routed on a 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 13 If you selected Fully Protected Path in Step 11 and the circuit will be routed on an SNCP DRI, click the Dual Ring Interconnect check box.

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

Step 15 Complete the "DLP-D98 Provision a High-Order Circuit Route" task.

Bidirectional—Leave checked for this circuit (default).

State—Choose a service state to apply to the circuit:

IS—The circuit is in service.

OOS—The circuit is out of service. Traffic is not passed on the circuit.

OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).

OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-13.

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 Loss of signal alarms appear if in service (IS) ports are not receiving signals.


Inter-domain (UCP) SLA—If the circuit will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.

Protected Drops—Uncheck this check box if it is selected.

Step 8 Complete the "DLP-D218 Provision SNCP Ring Selectors During Circuit Creation" task.

Step 9 Click Next.

Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 at an ONS 15454 SDH on the network where you will create 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 Provision and enable the Ethernet ports. See "DLP-D220 Provision E-Series Ethernet Ports" task.

Step 7 From the View menu, choose Go to Network View.

Step 8 Click the Circuits tab, then click Create.

Step 9 In the Create Circuits 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 10 Click Next.

Step 11 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).

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

Apply to drop ports—Uncheck this box.

Inter-domain (UCP) SLA—If the circuit will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.

Protected Drops—Leave the default unchanged (unchecked).

Step 12 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 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 TCC+/TCC2 card.

Step 13 Click Next.

Step 14 Provision the circuit source:

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

b. From the Slot drop-down menu, 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 15 Click Next.

Step 16 Provision the circuit destination:

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

b. From the Slot drop-down menu, 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 17 Click Next.

Step 18 In the Circuit VLAN Selection area, click New VLAN. If the VLAN already exists, continue with Step 21.


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 19 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 ID—Choose the topology ID from the drop-down menu.

Step 20 Click OK.

Step 21 In the Circuit VLAN Selection area, highlight the VLAN name and click the arrow button (>>) to move the available VLAN(s) to the Circuit VLANs column.

Step 22 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.


Note 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 on page 11-10.



Note 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 23 Click Next.

Step 24 Confirm that the following information about the circuit is correct:

Step 1 In the node view, double-click the Ethernet card that you want to provision.

Step 2 Click the Provisioning > Ether Port tabs.

Step 3 For each Ethernet port, provision the following parameters:

Port Name—If you want to label the port, type a port name.

Mode—Choose the appropriate mode for the Ethernet port:

Valid choices for the E100T-G card are Auto, 10 Half, 10 Full, 100 Half, or 100 Full.

Valid choices for the E1000-2-G card are 1000 Full or Auto.


Note Both 1000 Full and Auto mode set the E1000-2-G port to the 1000 Mbps and Full duplex operating mode; however, flow control is disabled when 1000 Full is selected. Choosing Auto mode enables the E1000-2-G card to autonegotiate flow control. Flow control is a mechanism that prevents network congestion by ensuring that transmitting devices do not overwhelm receiving devices with data. The E1000-2-G port handshakes with the connected network device to determine if that device supports flow control.


Enabled—Check this check box to activate the corresponding Ethernet port.

Priority—Choose a queuing priority for the port. Options range from 0 (Low) to 7 (High). Priority queuing (IEEE 802.1Q) reduces the impact of network congestion by mapping Ethernet traffic to different priority levels. Refer to the priority queuing information in the Cisco ONS 15454 SDH Reference Manual. This parameter does not apply to an E-Series card in port-mapped mode.

Stp Enabled—Click this check box to enable the Spanning Tree Protocol (STP) on the port. This parameter does not apply to an E-Series card in port-mapped mode. Refer to the spanning tree information in the Cisco ONS 15454 SDH Reference Manual.

Step 4 Click Apply.

Step 5 Repeat Steps 1 through 4 for all other cards in the VLAN or in port-mapped mode, repeat Steps 1 through 4 for the other card in a point-to-point circuit.

Step 1 In the node view, double-click the E-Series card graphic to open the card.

Step 2 Click the Provisioning > Ether VLAN tabs.

Step 3 To put a port in a VLAN:

a. Click the port and choose either Tagged or Untag. Table 8-5 shows valid port settings.

b. If a port is a member of only one VLAN, choose Untag from the Port column in the VLAN's row. Choose -- for all the other VLAN rows in that Port column.


Note The VLAN with Untag selected can connect to the port, but other VLANs cannot access that port.


c. Choose Tagged at all VLAN rows that need to be trunked. Choose Untag at VLAN rows that do not need to be trunked, for example, the default VLAN.


Note Each Ethernet port must be attached to at least one untagged VLAN. A trunk port connects multiple VLANs to an external device, such as a switch, which also supports trunking. A trunk port must have tagging (IEEE 802.1Q) enabled for all the VLANs that connect to that external device.


Step 4 After each port is in the appropriate VLAN, click Apply. Table 8-5 lists the VLAN settings.

Note You can provision a maximum of two VCAT circuits for ML-Series cards.



Note For FC_MR-4 cards with a line rate 2-Gbps fiber channel, an equivalent VCAT circuit does not exist. A contiguous VC-4-16c circuit is used instead.



Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-24 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 not, continue with Step 3.

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

Step 4 In the Circuit Creation dialog box, choose VC_HO_v or VC_LO_v from the Circuit Type drop-down menu.

Step 5 Click Next.

Step 6 Define the circuit attributes (Figure 8-15):

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 4. You cannot change it.

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

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If this box is checked, you cannot assign a name to the circuit. Also, low-order tunnels and Ethergroup sources and destinations are unavailable.

State—Choose a service state to apply to the circuit:

IS—The circuit is in service.

OOS—The circuit is out of service. Traffic is not passed on the circuit.

OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service (IS).

OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-D230 Change a Circuit State" task on page 11-13.

Apply to drop ports—Not applicable.

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

Member size—Choose the member size:

If the circuit type is VC_HO-v, choose VC4 or VC4-4c.

If the circuit type is VC-LO-v, choose VC3.

For FC_MR-4 cards, only VC4-8v is available.

Num. of members—For VCAT circuits on FC_MR-4 cards, choose 8. For VCAT circuits on ML-Series cards, choose 2.

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.

Sw-LCAS—Allows the VCAT circuit to adapt to member failures and keep traffic flowing after failures at a reduced bandwidth.

Step 7 Click Next.

Step 8 Complete the "DLP-D36 Provision a VCAT Circuit Source and Destination" task for the VCAT circuit you are creating.

Step 9 In the Circuit Routing Preferences area (Figure 8-16), uncheck Route Automatically.

Step 10 In the Member Preferences area, complete the following:

Number—Type a number (between 1 and 256) to identify the member.

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.

Protection—Choose the member protection type:

Fully Protected—Routes the circuit on a protected path.

Unprotected—Creates an unprotected circuit.

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

Set protection for all members—Allows you to choose the same protection type for all members.


Note If a member is unprotected, all members must be unprotected.


Step 11 Click Next. If you chose Fully Protected or PCA, click OK to continue. If not, continue with the next step.

Step 12 In the VC LO Circuit Options area, the default is None. You cannot change it. Click Next.

Step 13 In the Route Review and Edit area, node icons appear so you can route the circuit manually.

Step 14 Complete the "DLP-D26 Provision a VCAT Circuit Route" task.

Step 15 Click Finish. 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 16 When all the circuits are created, the Circuits window appears. Verify that the circuit you created appear in the window.

Step 17 Complete the "D62 Test High-Order Circuits" procedure.

Stop. You have completed this procedure.
