This chapter explains how to manage Cisco ONS 15454 electrical, optical and Ethernet circuits.
Before You Begin
To create circuits, see "Create Circuits and VT Tunnels."
To clear any alarm or trouble conditions, refer to the Cisco ONS 15454 Troubleshooting Guide.
This section lists the chapter procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).
1. 
NTP-150 Locate and View Circuits—Complete as needed.
2. NTP-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 UPSR circuits.
3. NTP-152 Delete Circuits—Complete as needed.
4. NTP-78 Create a Monitor Circuit—Complete as needed to monitor traffic on primary bidirectional circuits.
5. NTP-79 Create a J1 Path Trace—Complete as needed to monitor interruptions or changes to circuit traffic.
The ONS 15454 Circuits window ( Figure 9-1) displays information about circuits to help you manage the circuits. Two key attributes are status and state. Circuit status shown in Table 9-1, is CTC-generated information telling you what CTC has learned about the 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 9-1 ONS 15454 Circuit Status
Status
|
Definition/Activity
|
CREATING
|
CTC-created circuit is being created
|
ACTIVE
|
CTC-created circuit is complete. All components are in place and a complete path exists from circuit source to destination.
|
DELETING
|
Circuit is being deleted
|
INCOMPLETE
|
CTC-created circuit is missing a connection or circuit span (network link); a complete path from source to destination(s) does not exist, or an AIP (MAC address) change occurred on one of the circuit nodes and the circuit is in need of repair.
|
UPGRADABLE
|
A TL1-created circuit is complete and has upgradable connections. A complete path from source to destination(s) exists. The circuit may be upgraded.
|
INCOMPLETE_UPGRADABLE
|
TL1-created circuit with upgradable connections is missing a connection or circuit span (network link), and a complete path from source to destination(s) does not exist. The circuit cannot be upgraded until missing components are in place.
|
NOT_UPGRADABLE
|
TL1-created circuit is complete but has at least one non-upgradable connection. UPSR_HEAD, UPSR_EN, UPSR_DC, and UPSR_DROP connections are not upgradable, so all unidirectional UPSR circuits created with TL1 are not upgradable.
|
INCOMPLETE_NOT_UPGRADABLE
|
TL1-created circuit with one or more non-upgradable connections is missing a connection or circuit span (network link); a complete path from source to destination(s) does not exist.
|

Definition
|
IS
|
In service; able to carry traffic
|
OOS
|
Out of service; unable to carry traffic
|
OOS-AINS
|
Out of service, auto in service; traffic is carried, but alarms are suppressed and loopbacks are allowed. VT circuits generally switch to IS when source and destination ports are placed in IS, OOS_AINS, or OOS_MT regardless of whether a physical signal is present. STS circuits switch to IS when a signal is received.

Step 3 Choose the STS circuit you want to trace, then click Edit.
Step 4 On the Edit Circuit window, click the Show Detailed Map box at the bottom of the window. A detailed map of the source and destination ports is displayed.
Step 5 Provision the circuit source transmit string:
a. On the detailed circuit map right-click the circuit source port (square on the left or right of the source node icon) and choose Edit Path Trace from the shortcut menu. Figure 9-5 shows an example.
Figure 9-5 Selecting the Edit Path Trace option
b. In the New Transmit String field, enter the circuit source transmit string. Enter a string that makes the source port easy to identify, such as node IP address, node name, circuit name, or another string. If the New Transmit String field is left blank, the J1 transmits a string of null characters.
c. Click Apply, then click Close.
Step 6 Provision the circuit destination transmit string:
a. On the Edit Circuit window (with Show Detailed Map chosen, see Figure 9-5) right-click the circuit destination port and choose Edit Path Trace from the shortcut menu.
b. In the New Transmit String field, enter the string that you want the circuit destination to transmit. Enter a string that makes the destination port easy to identify, such as node IP address, node name, circuit name, or another string. If the New Transmit String field is left blank, the J1 transmits a string of null characters.
c. Click Apply.
Step 7 Provision the circuit destination expected string:
a. On the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual from the Path Trace Mode drop-down menu:
–Auto—the first string received from the source port is the baseline. An alarm is raised when a string that differs from the baseline is received.
–Manual—the string entered in Current Expected String is the baseline. An alarm is raised when a string that differs from the Current Expected String is received.
b. If you set Path Trace Mode to Manual, enter the string that the circuit destination should receive from the circuit source in the New Expected String field. If you set Path Trace Mode to Auto, skip this step.
c. Click the Disable AIS on TIM-P checkbox if you want to suppress the Alarm Indication Signal when the STS Path Trace Identifier Mismatch Path (TIM-P) alarm is displayed. Refer to the Cisco ONS 15454 Troubleshooting Guide for descriptions of alarms and conditions.
Note RDI (Remote Defect Indicator) conditions on TIM-P are not generated in this release.
d. Click Apply, then click Close.
Step 8 Provision the circuit source expected string:
a. On the Edit Circuit window (with Show Detailed Map chosen, see Figure 9-5) right-click the circuit source port and choose Edit Path Trace from the shortcut menu.
b. On the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual from the Path Trace Mode drop-down menu:
–Auto—Uses the first string received from port at the other end as the baseline string. An alarm is raised when a string that differs from the baseline is received.
–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.
c. If you set Path Trace Mode to Manual, enter the string that the circuit source should receive from the circuit destination in the New Expected String field. If you set Path Trace Mode to Auto, skip this step.
d. Click the Disable AIS on TIM-P checkbox if you want to suppress the Alarm Indication Signal when the STS Path Trace Identifier Mismatch Path (TIM-P) alarm is displayed. Refer to the Cisco ONS 15454 Troubleshooting Guide for descriptions of alarms and conditions.
e. Click Apply.
Step 9 After you set up the path trace, the received string is displayed in the Received box on the path trace setup window. Figure 9-6 shows an example. The following options are available:
•Click Hex Mode to display path trace in hexadecimal display. The button name changes to ASCII Mode. Click it to return the path trace to ASCII display.
•Click the Reset button to reread values from the port.
•Click Default to return to the path trace default settings (Path Trace Mode is set to Off and the New Transmit and New Expected Strings are null).
Caution Clicking Default will generate alarms if the port on the other end is provisioned with a different string.
The Expect and Receive strings are updated every few seconds as long as Path Trace Mode is set to Auto or Manual.
Step 10 Click Close.
When you display the detailed circuit window, path trace is indicated by an M (manual path trace) or an A (automatic path trace) at the circuit source and destination ports. Figure 9-7 shows an example.

DLP-137 Provision Path Trace on OC-N Ports
Purpose
|
Use this task to monitor a path trace on OC-N ports within the circuit path.
|
Tools/Equipment
|
ONS 15454 cards capable of receiving path trace must be installed at the OC-N circuit ports. See Table 9-3.

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 STS 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 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 OC-N port (square on the left or right of the source node icon) and choose Edit Path Trace from the shortcut menu.
Note The OC-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 drop-down menu:
•Auto—Uses the first string received from port at the other end as the baseline string. An alarm is raised when a string that differs from the baseline is received. For OC-N ports, Auto is recommended, since 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 Path Trace Mode to Manual, enter the string that the OC-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 Path Trace Mode to Auto, skip this step.
Step 8 Click the Disable AIS on TIM-P checkbox if you want to suppress the Alarm Indication Signal when the STS Path Trace Identifier Mismatch Path (TIM-P) alarm is displayed. Refer to the Cisco ONS 15454 Troubleshooting Guide for descriptions of alarms and conditions.
Step 9 Click Apply, then click Close.
