7.1  Overview

A metro network is a network that aggregates customer traffic and connects customers to services. The metro network is responsible for receiving network traffic from long-haul transport networks and routing this traffic to and from enterprises and end users.

The service point-of-presence (POP) performs service adaptation and packet switching. This layer performs the following functions:

•Grooming of traffic from the metro network

•Edge packet switching, where IP services are enabled

•Core packet switching, where POPs are interconnected over the IP backbone

The service POP is the hub of high-value Internet services. The core network, where optical technologies predominate, is the domain of the long-haul carrier. This high-speed transport fabric interconnects service POPs and has traditionally been built as SONET ring architectures.

CTM simplifies OSS integration for service providers for the end-to-end management of transport networks.

7.2  Managing Circuits

A circuit represents an end-to-end connection between two or more connection termination points (CTPs). A circuit consists of an alternating series of cross-connections and link connections. In its simplest form, a circuit consists of a single cross-connection (if the circuit is defined between two CTPs on the same NE). A circuit can be bidirectional or unidirectional, point-to-point (PTP) or point-to-multipoint, and protected or unprotected.

CTM allows you to create unidirectional and bidirectional circuits for CTC-based NEs. For unidirectional path switched ring (UPSR) circuits, you can create revertive or nonrevertive circuits. CTM can route the circuits automatically, or you can route them manually. For CTC-based NEs, circuits can be viewed, created, modified, traced, and deleted. For the ONS 15530 or ONS 15540, a circuit is an end-to-end connection between two ports on ONS 15530 or ONS 15540 NEs in terms of lambda (wavelength). For the ONS 155xx, circuit services provide the following major capabilities:

•Finding all end-to-end connections between NEs in terms of client ports, provided the entire path was traversed within ONS 15530 and ONS 15540 NEs.

•Displaying the protection information associated with each circuit.

•Displaying all directional-based paths that have been configured and are in use for a protected circuit.

•Displaying the active and standby paths that have been configured and are in use for a protected circuit.

Note Circuit information is not available for the ONS 15216, ONS 15302, ONS 15501, ONS 15800, ONS 15801, ONS 15808, Cisco CRS-1, Cisco Catalyst 6509, or Cisco XR 12000.

Note Circuit management performance depends on an efficient DCN network. Refer to the ONS 15454 user documentation for details.

Table 7-1 defines the circuit terms and options that are used throughout this chapter.

Table 7-1 Circuit Terms and Options

Circuit Option

Description

Link

Represents a topological relationship between two physical termination points (PTPs) for a particular layer rate. The possible set of layer rates is determined by the layer rates terminated by the PTP. For example, an OC-N port will terminate a physical layer rate and a SONET layer rate.

Circuit

Represents an end-to-end connection between two or more CTPs.

Cross-connection

A (normally flexible) connection between two CTPs within the same NE.

Link connection

An inflexible (or fixed) connection between two CTPs that are contained by two PTPs connected by a link. It represents a portion of the transport capacity of a link, such as an STS-1 channel within an OC-N link.

PTP

A termination point that is the actual or potential endpoint of a link that might be abstracted as a PTP. It is the representation of a physical port.

CTP

Represents the actual or potential endpoint of a cross-connection, link connection, or circuit. A CTP is contained within a PTP. In some cases, there is a single CTP associated with a PTP, such as with a DS-1 PTP. There could also be multiple CTPs, such as with STS-1 or STS-Nc CTPs contained within an OC-N PTP.

Source

The circuit source is where the circuit enters the network.

Destination

The circuit destination is where the circuit exits the network.

Automatic circuit routing

CTM 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 STS or VT for each circuit segment for SONET nodes, or a specific VC4, VC3, or VC12 for each circuit segment for SDH nodes. You can also create circuits from work orders prepared by an OSS such as the Telcordia TIRKS system.

Low-order tunnel

Low-order tunnels allow VC3 and VC12 circuits to pass through an SDH node without using cross-connect card (XC10G and XCVXL) resources. Low-order circuits using tunnels will use cross-connect capacity only at the source and destination nodes. One low-order tunnel can carry three VC3s, and each VC3 can carry 21 VC12s. One tunnel can carry one VC3 circuit span and 42 VC12 circuit spans, and each VC3 is a separate container that 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 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 subnetwork connection protection (SNCP) nodes.

VT tunnel

VT tunnels allow VT1.5 circuits to pass through a SONET node without utilizing cross-connect resources. VT circuits using VT tunnels will use cross-connect capacity only at the source and destination nodes. One VT tunnel can carry 28 VT1.5 circuits.

VT aggregation point

VT aggregation points (VAPs) allow VT circuits to be aggregated into an STS for handoff to non-ONS networks or equipment, such as IOFs, switches, or digital access cross-connect systems. VAPs reduce VT matrix resource utilization at the node where the VT1.5s are aggregated onto the STS. This node is called the STS grooming end. The STS grooming end requires an OC-N, EC-1, or DS3XM-6 card. VT aggregation points can be created on BLSR, 1+1, or unprotected nodes, but cannot be created on UPSR nodes.

7.2.3  Viewing the Circuit Table

The Circuit table (Figure 7-1) shows circuit information for all circuits that make up a topology. A circuit describes a fixed-size bandwidth pipe that is fully cross-connected from one user-defined source point (node, slot, or port) to a second user-defined destination point across some number of node-to-node optical spans (zero if the circuit is local to a single NE).

An endpoint can be an actual physical drop port (DS-1, DS-3, and so on) or an STS-n or VT1.5 channel in an optical line. A multicast circuit consists of circuit spans that have one source endpoint and a sequence of destination endpoints.

To launch the Circuit table, do any of the following:

•Select a node in the Domain Explorer tree and choose Configuration > CTC-based SONET NEs or CTC-based SDH NEs > Circuit Table

•Right-click a node in the Domain Explorer tree and choose Circuit Table

•Open the L2 Topology table and choose Configuration > Circuits

You can force all circuits involved with the upgraded card in the Circuit table to update by marking the NE as Out of Service and then In Service.

7.2.4  Creating Circuits Using the Circuit Wizard

The Create Circuit wizard (Configuration > Create Circuit) allows you to create circuits on CTC-based NEs. Use the Create Circuit wizard to create an end-to-end circuit through a subnetwork. A subnetwork is defined as a set of NEs that are interconnected directly or indirectly through links known by CTM. CTM supports circuit provisioning across a heterogeneous network. Establish a circuit by specifying the A and Z termination points (TPs). You can create multiple circuits using the Create Circuit wizard; however, for VT tunnel circuits, the number you can create is limited by the bandwidth available on the VT tunnel being used. The maximum number of VT circuits that can be routed through a VT tunnel is 28.

Caution When adding CTC-based circuits, examine the links in the network to ensure correct operation. If any links are down, verify that the ports are not data communications channel (DCC) enabled. For information about viewing links, see 3.6.3  Viewing the Link Table, page 3-35.

Note A new circuit can only be created within a subnetwork. You cannot create circuits across subnetworks.

–Required—Ensures that the primary and alternate paths are node-diverse.

–Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse.

–Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse. The paths might be node-diverse, but CTM does not check for node diversity.

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

•Set Node Diversity for All—Allows you to specify the same node diversity for all members.

Fully Protected Path

If selected, CTM ensures that the circuit is fully protected. You can provision the circuit in a UPSR DRI topology by checking Dual Ring Interconnect. Alternately, if the circuit must pass across unprotected links, CTM creates a primary and alternate circuit route (virtual UPSR) based on the following node diversity specifications:

•Required—Ensures that the primary and alternate paths of the UPSR portions of the complete circuit path are node-diverse.

•Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path.

•Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. The paths might be node-diverse, but CTM does not check for node diversity.

Protection Channel Access

To route the circuit on a BLSR protection channel, if available, uncheck the Fully Protected Path check box, and check the Protection Channel Access check box.

Dual Ring Interconnect

If you selected Fully Protected Path and the circuit will be routed on a DRI, check the Dual Ring Interconnect check box.

Note For DRI and iDRI manually created circuits, you must double-click the DRI span for it to become DRI. A single-click does not enable the DRI span.

VT/VC LO Circuit Options

(available only for VT and VC LO path circuits)

VT/VC LO Tunnel on Transit Nodes

This option is available if the VT or VC 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 VT/VC circuits to pass through NEs without consuming low-order cross-connect card resources. In general, creating tunnels is a good idea if you are creating many low-order circuits from the same source and destination.

VT Aggregation Point (VAP)/VC LO Aggregation Point (LAP)

(For SONET) This option is available if you are creating a VT1.5 circuit to a DS-1, EC-1, DS3XM-6; or an OC-N port on a BLSR, 1+1, or Unprotected node. A VAP allows VT1.5 circuits to be routed through a node using one STS connection on the cross-connect card matrix rather than multiple connections on the VT1.5 matrix.

(For SDH) This option is available if you are creating a VC12 circuit to an STM-N port for handoff to non-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.

Circuit Source is STS/VC4 Grooming Node

Creates the VAP or LAP on the VT or VC circuit source node. This option is available only if the VT circuit originates on a DS-1, EC-1, DS3XM-6, or OC-N card, or if the VC circuit originates on an STM-N card.

Circuit Destination is STS/VC4 Grooming Node

Creates the VAP or LAP on the VT or VC circuit destination node. This option is available only if the VT circuit terminates on a DS-1, EC-1, DS3XM-6, or OC-N card, or if the VC circuit terminates on an STM-N card.

None

Choose this option if you do not want to create a low-order tunnel or a VAP/LAP. This is the only available option if CTM cannot create a low-order tunnel or VAP/LAP.

VLAN Selection

(available only for Ethernet cards or EtherGroups)

VLANs

Select from the list of available VLANs to associate an existing VLAN to the circuit. If the Circuit VLANs list is empty, CTM assigns the default VLAN.

To create a new VLAN, click the New VLAN button. Enter a unique VLAN name and ID. The VLAN ID must be an integer greater than 1 but less than 4093. Click OK; then, click OK in the Successfully created VLAN confirmation dialog box. The new VLAN appears in the list of VLANs. The list is ordered alphanumerically by VLAN name, where numbers precede letters and uppercase letters precede lowercase ones.

Note Gigabit Ethernet G-series, ML-series, and E-series cards that are configured in port ML-series mode do not support VLAN assignment.

7.2.4.2  Creating a VCAT Circuit

This section describes how to create VCAT circuits (STS-v, VT-v, VC_HO_PATH_VCAT_CIRCUIT, or VC_LO_PATH_VCAT_CIRCUIT). For SDH nodes, only VC_HO_PATH is supported for VCAT circuits.

VCAT circuits are supported on the following cards:

•ML1000, ML100T—Supported on ONS 15454 SONET and ONS 15454 SDH NEs

•FCMR—Supported on ONS 15454 SONET and ONS 15454 SDH NEs

•CE-100T-8—Supported only on ONS 15454 SONET NEs

•ML-100T-8—Supported on ONS 15310 NEs

Note Each card supports a different number of members. You can create only bidirectional, revertive or nonrevertive, and high-order/low-order path circuits. CTM can route the circuits automatically, or you can route them manually. Also, all members can be routed through a single fiber or you can specify a split fiber routing preference.

Step 1 Select the node for which to create a VCAT circuit and open the Circuit wizard. For an explanation of Circuit wizard launch points, see Table 7-5.

Step 2 In the Type pane, select STS-v, VT-v, VC_HO_PATH_VCAT_CIRCUIT, or VC_LO_PATH_VCAT_CIRCUIT. (For SDH nodes, only VC_HO_PATH is supported for VCAT circuits.) In the Number of Circuits field, enter the number of circuits you want to create. The Cisco default is 1. If you enter more than one, you can use autoranging to create the additional circuits automatically.

Note You can create only one VCAT circuit at a time.

Step 3 In the Attributes pane, enter the following information; then, click Next:

•Name—Enter a unique name for the new circuit. For VCAT circuits, the circuit name is a free-format string, up to 44 ASCII characters.

•Description—Enter a circuit description of up to 256 characters.

•State—Specify IS, OOS_DSBLD, OOS_MT, IS_AINS, or OOS_OOG (Out of Service-Out of Group).

•Apply to source/destination ports—Check this check box to apply the selected state to the source and destination ports.

•Member Size—Select the size of the member for the VCAT circuit. This is the unit for VCAT circuit size.

•Number of Members—Select the number of members (of the size selected above). Different cards support different numbers of members with different sizes.

•Mode—Select the LCAS mode (None, Sw-LCAS, or LCAS) for the VCAT circuit. If other than None is selected as the Mode, only the cards supporting the LCAS mode selected will be listed for the source and destination selection.

•Protected Drops—Check this check box if you want the circuit routed to protected drops only; that is, to cards that are in 1:1, 1:N, or 1+1 protection.

•Provision working go and return on primary path (bidirectional UPSR/SNCP protection only)—Check this check box to provision the working path to go and return to the primary path.

•SNCP path selector defaults—If the circuit will be routed on an SNCP, set the defaults as follows:

–Revertive—Check this check box if you want traffic to revert to the working path when the conditions that diverted it to the protect path are repaired. If Revertive is not chosen, traffic remains on the protect path.

–Reversion time—If Revertive is checked, set the reversion time. 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. (The Cisco default reversion time is 5 minutes.)

–SF threshold—Choose from 1 E-3, 1 E-4, or 1 E-5.

–SD threshold—Choose from 1 E-5, 1 E-6, 1 E-7, 1 E-8, or 1 E-9.

Step 7 Click Next.

Step 8 In the Routing Preferences pane, complete the following substeps; then, click Next:

a. Route Automatically—Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. If the source and destination of the circuit are on the same node, automatic routing is enabled automatically. If disabled, you can specify the spans associated with the circuit. Under the Manual Route area, the Graphical radio button is selected by default.

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let CTM automatically route the circuit through the required nodes and/or links.

c. Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

d. Select the routing preference for VCAT members. If all members are to be routed on a single fiber, choose Common Fiber Routing. If members are to be routed through different fibers in case one fiber does not have sufficient bandwidth, choose Split Routing.

e. Specify the following member preferences:

•Number—Select the member number, a unique number from 1 to 256.

•Name—Edit the name for the member circuit. By default, <VCAT_NAME>_<Default MemberNumber> is the member name, where <VCAT_NAME> is the parent VCAT circuit name being created.

•Protection—Select the protection mechanism for member circuits. To route the circuit on a protected path, choose Fully Protected (default). A fully protected circuit route is created based on the diversity option you choose. Fully protected paths might or might not have UPSR/SNCP path segments with primary and alternate paths. The path diversity options apply only to UPSR/SNCP path segments, if any exist. To create an unprotected circuit, choose Unprotected.

•Node Diversity—Select node diversity for each member circuit.

f. If you selected Fully Protected Path, choose one of the following options:

•Required—Ensures that the primary and alternate paths within the extended UPSR/SNCP mesh network portions of the complete circuit path are nodally diverse.

•Desired—Specifies that node diversity is preferred, but if node diversity is not possible, link-diverse paths are created for the extended UPSR/SNCP mesh network portion of the complete circuit path.

•Link Diverse Only—Specifies that only link-diverse primary and alternate paths for extended UPSR/SNCP mesh network portions of the complete circuit path are needed.

•N/A (Not Applicable)—Dual Ring Interconnect is not supported from CTM.

Note Node diversity can be set for each member when Fully Protected is selected and Split Fiber Routing is selected.

Step 9 In the Manual Provisioning pane (available when Route Automatically is unchecked), a graphical representation of the circuit is displayed, including source and destination nodes. Select the member from the Member list box at the top of the pane. You must select each member and route the member from source to destination manually, by selecting spans and adding them to the route until the destination is reached. When the member selection is changed, the display is refreshed for the new member. Complete the following substeps; then, click Finish:

a. In the VCAT Member Number list box, select the member for which the route is to be selected.

7.2.4.10  Creating G1000-4 Circuits

This section explains how to provision G1000-4 point-to-point circuits and Ethernet manual cross-connects. Ethernet manual cross-connects allow you to cross-connect individual Ethernet circuits to an STS channel on the ONS 15454 SONET or ONS 15454 SDH optical interface and to bridge non-ONS SONET network segments.

7.2.4.10.1  G1000-4 Point-to-Point Ethernet Circuits

G1000-4 cards support point-to-point circuit configuration. Provisionable circuit sizes are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, and STS-48c. Each Ethernet port maps to a unique STS circuit on the SONET side of the G1000-4.

The G1000-4 card supports any combination of up to four circuits from the list of valid circuit sizes; however, the circuit sizes can add up to no more than 48 STSs. Due to hardware constraints, the initial release of the G1000-4 card (software release 3.2) imposes additional restrictions on the combinations of circuits that can be dropped onto a G1000-4 card. These restrictions are transparently enforced by the ONS 15454 SONET and ONS 15454 SDH, so there is no need to keep track of restricted circuit combinations.

•The restriction occurs when a single STS-24c is dropped on a card. In this instance, the remaining circuits on that card can be another single STS-24c or any combination of circuits of STS-12c size or smaller that add up to no more than 12 STSs (that is, a total of 36 STSs on the card).

•No circuit restrictions are present if STS-24c circuits are not being dropped on the card. The full 48 STSs of bandwidth can be used (for example, a single STS-48c circuit or 4 STS-12c circuits).

•Since the restrictions apply only when STS-24c circuits are involved but do not apply when two STS-24c circuits are on the same card, the impact of these restrictions can be easily minimized. Group the STS-24c circuits together on a card separate from circuits of other sizes. The grouped circuits can be dropped onto other G1000-4 cards on the ONS 15454 SONET or ONS 15454 SDH. The G1000-4 uses STS cross-connects only. No VT-level cross-connects are used. All SONET-side STS circuits must be contiguous.

Caution G1000-4 circuits connect with OC-N cards or other G1000-4 cards. G1000-4 cards do not connect with E-series Ethernet cards.

Caution The G1000-4 card requires the XC10G card to operate. The G1000-4 card is not compatible with XC or XCVT cards.

Step 1 In the Domain Explorer, select the ONS 15454 SONET or ONS 15454 SDH NE that will be used as one of the Ethernet circuit endpoints.

Step 2 Complete the following in the Domain Explorer:

a. Select the source circuit.

b. Choose Configuration > Create Circuit.

c. Select the destination circuit. The Create Circuit wizard opens.

Step 6 Verify that the Bidirectional check box is checked.

Note The states of the Number of Circuits check box and the Protected Drops check box are provided.

Caution If provisioning a G1000-4 circuit on a UPSR, do not check the Switch on PDI-P check box. Checking the Switch on PDI-P check box might cause unnecessary UPSR protection switches.

Step 16 Click Next. The Routing Preferences pane opens.

Step 17 In the Circuit Summary section, verify the following information about the point-to-point circuit:

•Circuit name

•Circuit type

•Circuit size

•ONS 15454 SONET or ONS 15454 SDH nodes are included in the circuit

Step 18 Click Finish.

Step 19 To change the slot property information for the Ethernet card, see C.4.11  Slot Properties—G1000-4, page C-543.

Note To change the capacity of a G1000-4 point-to-point circuit, delete the original circuit and reprovision a new, larger circuit.

7.2.4.10.2  G1000-4 Manual Cross-Connects

ONS 15454 SONET and ONS 15454 SDH NEs require end-to-end CTC visibility between nodes for normal provisioning of Ethernet circuits. When equipment from other vendors is placed between the ONS 15454 SONET and ONS 15454 SDH, equipment based on Open System Interconnection/Target Identifier Address Resolution Protocol (OSI/TARP) does not allow tunneling of the ONS 15454 SONET or ONS 15454 SDH TCP/IP-based data communications channel (DCC). To circumvent a lack of continuous DCC, the Ethernet circuit must be manually cross-connected to an STS channel riding through the non-ONS network. This allows an Ethernet circuit to run from ONS node to ONS node while utilizing the non-ONS network.

Note In this chapter, cross-connect and circuit have the following meanings: Cross-connect refers to the connections that occur within a single ONS 15454 SONET or ONS 15454 SDH to allow a circuit to enter and exit an ONS 15454 SONET or ONS 15454 SDH. Circuit refers to the series of connections from a traffic source (where traffic enters the ONS 15454 SONET or ONS 15454 SDH network) to the drop or destination (where traffic exits an ONS 15454 SONET or ONS 15454 SDH network).

Step 1 In the Domain Explorer, select the ONS 15454 SONET and ONS 15454 SDH Ethernet circuit endpoint nodes.

Step 2 Complete the following in the Domain Explorer:

a. Select the source circuit.

b. Choose Configuration > Create Circuit.

c. Select the destination circuit. The Create Circuit wizard opens.

Step 3 From the Type field, choose STS; then, click Next. The Attributes pane opens.

Note The VT and VT Tunnel types do not apply to Ethernet circuits.

Step 4 In the Name field, enter a name for the circuit.

Step 5 From the Size field, choose the size of the circuit. The valid circuit sizes for a G1000-4 circuit are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, and STS-48c.

Step 6 Verify that the Bidirectional check box is checked.

Step 7 (Optional) Specify the customer information:

•Customer ID

•Service ID

Step 8 Click Next.

Step 9 In the Source pane, choose the circuit source node.

Step 10 From the Slot field, choose the slot containing the Ethernet card.

Step 11 From the Port field, choose a port.

Step 12 Click Next.

Step 13 In the Destination pane, choose the current node as the circuit destination.

Step 14 From the Slot field, choose the optical card that will carry the circuit.

Step 15 Choose the STS that will carry the circuit from the STS field; then, click Next. The Routing Preferences pane opens.

Note For Ethernet manual cross-connects, the same ONS 15454 SONET or ONS 15454 SDH serves as both source and destination.

Step 16 In the Circuit Summary pane, verify the following information:

•Circuit name

•Circuit type

•Circuit size

•ONS 15454 SONET or ONS 15454 SDH nodes are included in this circuit

Note If the circuit information is not correct, click the Back button; then, redo the procedure with the correct information. Alternately, click Finish; then, delete the completed circuit and start the procedure from the beginning.

Step 17 Click Finish.

Step 18 Provision the Ethernet ports. For port provisioning instructions, see 6.5.1  Provisioning E-Series Ethernet Ports for VLAN Membership, page 6-13.

Step 19 To complete the procedure, repeat Steps 1 to 17 for the second ONS 15454 SONET or ONS 15454 SDH.

Note The appropriate STS circuit must exist in the non-ONS 15454 SONET or non-ONS 15454 SDH equipment to connect the two STSs from the ONS 15454 SONET or ONS 15454 SDH Ethernet manual cross-connect endpoints.

Caution If a CARLOSS alarm repeatedly appears and clears on an Ethernet manual cross-connect, the two Ethernet circuits might have a circuit-size mismatch. For example, a circuit size of STS-3c might have been configured on the first ONS 15454 SONET or ONS 15454 SDH, and a circuit size of STS-12c might have been configured on the second ONS 15454 SONET or ONS 15454 SDH. To troubleshoot the cause of the CARLOSS alarm, refer to the "Alarm Troubleshooting" chapter of Cisco ONS 15454 Troubleshooting Guide or Cisco ONS 15454 SDH Troubleshooting Guide.

7.2.4.11  Creating E-Series Circuits

Ethernet circuits can link ONS nodes through point-to-point, shared packet ring, or hub-and-spoke configurations. Two nodes usually connect with a point-to-point configuration. More than two nodes usually connect with a shared packet ring configuration or a hub-and-spoke configuration. This section includes procedures for creating these configurations and also explains how to create Ethernet manual cross-connects. Ethernet manual cross-connects allow you to cross-connect individual Ethernet circuits to an STS channel on the ONS 15454 SONET or ONS 15454 SDH optical interface and also to bridge non-ONS SONET network segments.

Note Before creating Ethernet connections, choose an STS-1, STS-3c, STS-6c, or STS-12c circuit size.

Note When creating an STS-12c Ethernet circuit, Ethernet cards must be configured as single-card EtherSwitch. Multicard mode does not support STS-12c Ethernet circuits.

7.2.4.11.4  E-Series Ethernet Manual Cross-Connects

ONS 15327, ONS 15454 SONET, and ONS 15454 SDH NEs require end-to-end CTC visibility between nodes for normal provisioning of Ethernet circuits. When equipment from other vendors is positioned between ONS 15327, ONS 15454 SONET, or ONS 15454 SDH NEs, equipment based on OSI/TARP does not allow tunneling of the ONS 15327, ONS 15454 SONET, or ONS 15454 SDH TCP/IP-based DCC. To circumvent this lack of continuous DCC, the Ethernet circuit must be manually cross-connected to an STS channel riding through the non-ONS network. This allows an Ethernet circuit to run from ONS node to ONS node by utilizing the non-ONS network.

Note Provisioning manual cross-connects for multicard EtherSwitch circuits is a separate procedure from provisioning manual cross-connects for single-card EtherSwitch circuits. Both procedures are provided in the following sections.

7.2.4.11.5  Provisioning a Single-Card EtherSwitch Manual Cross-Connect

7.2.8  Updating Circuits on CTC-Based NEs

You must update circuits after adding nodes to the network.

Step 1 In the Domain Explorer tree, select the CTC-based NE and choose Configuration > CTC-based SONET NEs or CTC-based SDH NEs > Update Circuit. A message appears, stating that CTM has successfully updated the circuit.

Step 2 Click OK.

7.2.9  Merging Circuits on CTC-Based NEs

Use the circuit merge feature to merge different circuits into one or more new circuits. This feature enables you to merge many circuits (including TL1 circuits), thereby ensuring that the aligned sections are spliced into one circuit.

Step 1 In the Domain Explorer tree, select the CTC-based NE and choose Configuration > CTC-based SONET NEs or CTC-based SDH NEs > Circuit Table.

Step 2 In the Circuit table, select the circuit; this circuit will be the master circuit.

Step 3 Choose Configuration > Merge Table. The fields in the Circuit Merge table are identical to the fields in the Circuit table (Table 7-3). The Circuit Merge table displays the circuits that are path aligned with the master circuit. These circuits are called slave circuits. The Circuit Merge table shows circuits (slave circuits) that are the same size as the master circuit.

Note You must merge n selected slave circuits with one selected master circuit. When circuits are merged from CTM, EMS attributes such as customer ID, service ID, description, and comments are retained only for master circuits. If the circuit merge is done through CTC, the EMS attributes are not retained in CTM.

Note Circuits are allowed to merge only if the following conditions exist:
— Their connections are path aligned.
— They have compatible circuit type, size, and direction.
— They do not have different VLAN assignments.
— They do not have different nondefault SLA values.
— They have compatible circuit endpoints.
— They do not form an invalid circuit.

Step 4 To refresh any new aligned circuits with the selected circuit, choose Configuration > Refresh Lined Up Circuits (or click the Refresh Lined Up Circuits tool).

Step 5 Specify the circuit(s) that you want to merge with the selected circuit and choose Configuration > Merge (or click the Merge tool).

Step 6 If the selected circuit(s) cannot be merged completely into the current circuit, the following dialog box appears:
The selected circuit(s) cannot be merged completely into the current circuit. Disjointed 
remnants of the selected circuit(s) might remain after the merge. Click OK to continue.
Step 7 Click OK to continue with the merge, or click Cancel to cancel the operation.

Note The EMS attributes of the circuits are lost after the circuit reconfigure.

Step 8 To reconfigure circuits, return to the Circuit table, select the circuit(s) to reconfigure, and choose Configuration > Reconfigure Circuit(s). A progress bar displays the status of the reconfiguration. A failed or succeeded message displays the results of the reconfiguration.

7.2.10  Repairing a Circuit

The Alarm Interface Panel (AIP) provides surge protection for CTC-based NEs. This pane has a nonvolatile memory chip that stores the unique node address known as the MAC address. The MAC address identifies the nodes that support circuits. It allows CTM to determine circuit sources, destinations, and spans. If an AIP fails, an alarm will be generated and the LCD display on the fan tray assemblies of the NEs will go blank. To perform an in-service replacement of the AIP, you must contact the Cisco Technical Assistance Center (TAC). For contact information, go to the TAC website at http://www.cisco.com/tac.

You can replace the AIP on an in-service system without affecting traffic by using the circuit repair feature. If the AIP card needs to be replaced, you will need to repair circuits affected by the MAC address change on the NE. Circuit repair will work when all nodes are running the same software version. Each individual AIP replacement requires an individual circuit repair; if AIPs are replaced on two NEs, the circuit repair must be performed twice. Repairing circuits allows you to change the MAC address of all circuits originating at an NE to a user-provided NE ID. To repair a CTM circuit when an AIP card is changed, restart the CTM server or complete the following steps:

Note While completing the following steps, do not create or delete any circuits using CTM.

Note The following procedure applies to circuits on CTC-based NEs.

Step 1 Refer to Cisco ONS 15454 Reference Manual to replace the AIP card.

Note Reset both Timing Communications and Control (TCC) cards after the AIP card is replaced.

Step 2 In the Domain Explorer, choose Administration > Control Panel.

Step 3 Expand NE Service.

Step 4 Select ONS 15310/ONS 15327/ONS 15454/ONS 15600 or ONS 15454 SDH/ONS 15600 SDH and deactivate the NE service.

Step 5 Activate the NE Service again and click Save.

Step 6 In the Domain Explorer, select the CTC-based NE and choose Configuration > CTC-based SONET NEs or CTC-based SDH NEs > Repair Circuit. The Repair Circuit dialog box opens.

The Repair Circuit dialog box allows you to change the MAC address of all circuits originating at the selected NE with a user-provided NE ID. MAC addresses are a subset of data link layer addresses. MAC addresses identify network entities in LANs implementing the IEEE MAC sublayer of the data link layer. Table 7-10 describes the fields in the Repair Circuit dialog box.

Step 7 After making your selections, click OK.

Table 7-10 Field Descriptions for the Repair Circuit Dialog Box

Field

Description

Old MAC Address

Enter the current MAC address of the NE. MAC addresses are 48 bits in length and are expressed as 12 hexadecimal digits (0-9, a-f):

•The first 6 hexadecimal digits are the manufacturer identification (or vendor code), called the Organizational Unique Identifier (OUI). These 6 digits are administered by the IEEE.

•The last 6 hexadecimal digits are the interface serial number or another value administered by the specific vendor.

New MAC Address

Enter the new MAC address of the NE.

7.2.11  Deleting a Circuit on CTC-Based NEs

Use the Circuit table to delete an existing circuit or multiple circuits from the CTM database and remove the associated cross-connections from the NEs.

7.2.18  Creating VCAT Member Circuits

Use the Add Member wizard to add new members to an existing VCAT circuit.

Note•You can launch the Add Member wizard only for VCAT circuits that allow reconfiguration.

•VCAT circuits created using TL1, cannot be re-configured (Add/Delete Member) until the parent VCAT circuit is re-configured (Configuration > Reconfigure Circuit(s) in the Circuit Table).

Step 1 Select a CTC-based NE in the Domain Explorer tree and choose Configuration > CTC-based SONET NEs or CTC-based SDH NEs > Circuit Table.

Step 2 In the Circuit table, choose Configuration > Member Circuits.

Step 3 In the VCAT Member table, choose Configuration > Add Member. The Add Member wizard opens. Table 7-17 provides descriptions.

Step 4 In the Add Members pane, specify the number of members to add to the existing VCAT circuit. Choose the administrative state for the new VCAT member circuit. All of the other panes (Routing Preferences, Manual Provisioning, Route Constraints, Review Route, and so on) are identical to the Create Circuit wizard. (See Table 7-7.)

Step 5 Click Next to proceed through the wizard panes. After finalizing your selections, click Finish.
