Manage Circuits


This chapter explains how to manage Cisco ONS 15454 SDH electrical, optical and Ethernet circuits.

Before You Begin

To create circuits, see Chapter 6, "Create Circuits and Low-Order Tunnels."

To clear any alarm or trouble conditions, refer to the Cisco ONS 15454 SDH Troubleshooting Guide.

This section lists the chapter procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).

1. 199 Locate and View Circuits—Complete as needed.

2. 200 View Cross-Connect Card Resource Usage—Complete as needed.

3. 151 Modify Circuit Characteristics—Complete as needed to edit a circuit name, change the active and standby colors of spans, or change signal fail, signal degrade thresholds, reversion time, and PDI-P settings for SNCP ring circuits.

4. 152 Delete Circuits—Complete as needed.

5. 78 Create a Monitor Circuit—Complete as needed to monitor traffic on primary bidirectional circuits.

6. 79 Create a J1 or J2 Path Trace—Complete as needed to monitor interruptions or changes to circuit traffic.

Figure 9-1 shows the Cisco Transport Controller Circuits window. This window displays information about circuits to help you manage the circuits, including circuit status and state.

Figure 9-1 ONS 15454 SDH Circuit Window In Network View

Table 9-1 lists the statuses that CTC can report for each circuit.

Table 9-1 ONS 15454 SDH 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 the circuit source to the circuit destination.

DELETING

CTC is deleting a circuit.

INCOMPLETE

A CTC-created circuit is missing a cross-connect or circuit span (network link), a complete path from source to destination(s) does not exist, or an Alarm Interface Panel (AIP) change occurred on one of the circuit nodes and the circuit is in need of repair. (AIPs store the node MAC address.)

An INCOMPLETE status does not always mean circuit traffic is dropped. It means the circuit is not complete within the parameters defined for it during circuit creation.


Circuit state, shown in Table 9-2, is a user-assigned, administrative status that defines whether the circuit is in or out of service. To carry circuit traffic, circuits must have a status of Active and a state of In Service (IS).

Table 9-2 ONS 15454 SDH Circuit States

State
Definition

IS

In service; able to carry traffic

OOS

Out of service; unable to carry traffic

OOS-AINS

Out of service, auto in service; alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether their alarms are reported or not, can be retrieved on the CTC Conditions tab. Low-order circuits generally switch to IS when source and destination ports are IS, OOS_AINS, or OOS_MT regardless of whether a physical signal is present. High-order circuits switch to IS when a signal is received.

OOS-MT

Out of service, maintenance; alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether their alarms are reported or not, can be retrieved on the CTC Conditions tab.

Note To monitor the J1 path on STM-N ports, the circuit endpoints must be transmitting VC4 J1 and not VC3 J1.



Step 1 Display the node where path trace was provisioned on the circuit source and destination ports.

Step 2 Click Circuits.

Step 3 Choose the VC4 circuit that has path trace provisioned on the source and destination ports, then click Edit.

Step 4 On the Edit Circuit window, click the Show Detailed Map check box at the bottom of the window. A detailed circuit graphic showing source and destination ports is displayed.

Step 5 On the detailed circuit map right-click the circuit STM-N port (the square on the left or right of the source node icon) and choose Edit Path Trace from the shortcut menu.


Note The STM-N port must be on a receive-only card listed in Table 9-3. If not, the Edit Path Trace menu item will not display.


Step 6 On the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual from the Path Trace Mode pull-down menu:

Auto—Uses the first string received from the port at the other path trace end as the current expected string. An alarm is raised when a string that differs from the baseline is received. For STM-N ports, Auto is recommended because Manual mode requires you to trace the circuit on the Edit Circuit window to determine whether the port is the source or destination path.

Manual—Uses the Current Expected String field as the baseline string. An alarm is raised when a string that differs from the Current Expected String is received.

Step 7 If you set the Path Trace Mode field to Manual, enter the string that the STM-N port should receive in the New Expected String field. To do this, trace the circuit path on the detailed circuit window to determine whether the port is in the circuit source or destination path, then set the New Expected String to the string transmitted by the circuit source or destination. If you set the Path Trace Mode field to Auto, skip this step.

Step 8 Click Apply, then click Close.
