Manage Circuits
This chapter explains how to manage CiscoONS15600SDH optical circuits.
Note 
The ONS15600SDH Software Release 1.4 does not support a full state model. As a result, the circuit state cannot be changed; it is always In Service (IS).
Before You Begin
To create circuits, complete the procedures as needed in "Create Circuits"
To clear any alarm or trouble conditions, refer to the CiscoONS15600SDH Troubleshooting Guide.
This section lists the chapter procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).
1. F60 Locate and View Circuits—Complete as needed.
2. F61 Modify and Delete Circuit Characteristics—Complete as needed to edit a circuit name, change the active and standby colors of spans, or change signal fail thresholds, signal degrade thresholds, and reversion time.
3. F62 Monitor a J1 Path Trace—Complete as needed to monitor interruptions or changes to circuit traffic.
4. F63 Bridge and Roll Traffic—Complete as needed to reroute circuits.
5. F64 Convert Circuits to TL1 Cross-Connections— Complete as needed to repair missing cross-connects or change cross-connects using the TL1-like circuit option.
6. F65 Upgrade TL1 Cross-Connects to CTC Circuits—Complete as needed if you want to convert TL1 cross-connects or TL1-like cross-connects created in Cisco Transport Controller (CTC) into a CTC circuit.
Note To provision ONS15600SDH circuits from an ONS 15454 node, the CTC version launched from the ONS 15454 must be Software R4.1 or later. Cisco recommends launching CTC from the ONS15600SDH node before provisioning circuits.

•Name—The name of the circuit (user-assigned or automatically generated).
•Type—For the ONS 15600 SDH, the circuit type is HOP (VC_HO_PATH_CIRCUIT) .
•Size—The VC_HO_PATH_CIRCUIT size can be VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, VC4-16c, or VC4-64c.
•Protection—The protection type; see Table 9-1 for a description of the possible values.
Table 9-1 Circuit Protection Types
|
Protection Type
|
Description
|
|
—
|
Circuit protection is not applicable.
|
|
2F MS-SPR
|
The circuit is protected by a 2-fiber multiplex section-shared protection ring (MS-SPRing).
|
|
SNCP
|
The circuit is protected by subnetwork connection protection (SNCP).
|
|
1+1 (LMSP)
|
The circuit is protected by a 1+1 (LMSP (Linear Multiplex Section Protection)) protection group.
|
|
Protected
|
The circuit is protected by diverse SDH topologies, for example, MS-SPRing and SNCP, or SNCP and 1+1.
|
|
Unprot (black)
|
The circuit is not protected.
|
|
Unprot (red)
|
The circuit was created as a fully protected circuit, but is no longer protected due to a system change, such as a traffic switch.
|
|
Unknown
|
Circuit protection types display in the Protection column only when all circuit components are known, that is, when the circuit status is ACTIVE or UPGRADABLE. If the circuit is in some other status, protection type is displayed as "unknown."
|
•Direction—The circuit direction, either two-way or one-way.
•Status—The circuit status; see Table 9-2 for a description of the possible values.
Table 9-2 Circuit Status
|
Status
|
Definition/Activity
|
|
CREATING
|
CTC is creating a circuit.
|
|
ACTIVE
|
CTC created a circuit. All components are in place and a complete path exists from circuit source to destination.
|
|
DELETING
|
CTC is deleting a circuit.
|
|
INCOMPLETE
|
Indicates one of the following:
•A CTC-created circuit is missing a connection or network span (network link).
•A complete path from source to destination(s) does not exist.
•A MAC address change occurred on one of the circuit nodes and the circuit is in need of repair.
In CTC, circuits are represented using cross-connects and network spans. If a network span is missing from a circuit, the circuit status is INCOMPLETE. However, an INCOMPLETE status does not necessarily mean a circuit traffic failure has occurred, for traffic might flow on a protect path.
Network spans are in one of two states: up or down. On CTC circuit and network maps, up spans appear as green lines, and down spans appear as gray lines. If a failure occurs on a network span during a CTC session, the span remains on the network map but its color changes to gray to indicate the span is down. If you restart your CTC session while the failure is active, the new CTC session cannot discover the span and its span line will not appear on the network map.
Subsequently, circuits routed on a network span that goes down will appear as ACTIVE during the current CTC session, but they will appear as INCOMPLETE to users who log in after the span failure.
|
•Source—The circuit source in the format: node/slot/port "port name".
•Destination—The circuit destination in the node/slot/port "port name".
•# of VLANS—The number of VLANs used by an Ethernet circuit (future use for the ONS 15600 SDH).
•# of Spans—The number of internode links that compose the circuit.
•State—The circuit state. The ONS 15600 SDH Release 1.4 does not support a full state model. As a result, you cannot change the circuit state; it is always IS.

Step13 To route the circuit over a protected path, check Fully Protected Path . (If you do not want to route the circuit on a protected path, continue with Step14.) CTC creates a primary and alternate circuit route (virtual SNCP) based on the following nodal diversity options. Select one of the following and follow subsequent window prompts to complete the routing:
•Nodal Diversity Required—Ensures that the primary and alternate paths within path-protected mesh network (PPMN) portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity should be attempted, but if node diversity is not possible, CTC creates link diverse paths for the PPMN portion of the complete circuit path.
•Link Diversity Only—Specifies that only link-diverse primary and alternate paths for PPMN portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step14 If you checked Route Automatically in Step12:
•If you checked Using Required Nodes/Spans, continue with Step 15 .
•If you checked both Using Required Nodes/Spans and Review Route Before Creation, continue with Step 15 .
•If you checked only Review Route Before Creation, continue with Step 16 .
