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 manage Cisco ONS 15454 electrical, optical and Ethernet circuits.

Before You Begin

To create circuits, see Chapter 6, "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. 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 path protection configuration circuits.

4. 416 Convert a CTC Circuit to TL1 Cross-Connects—Complete this procedure if you want to convert a CTC circuit into TL1 cross-connects.

5. 417 Upgrade TL1 Cross-Connects to CTC Circuits—Complete this procedure if you want to convert TL1 cross-connects or TL1-like cross-connects created in CTC into a CTC circuit.

6. 152 Delete Circuits—Complete as needed.

7. 78 Create a Monitor Circuit—Complete as needed to monitor traffic on primary bidirectional circuits.

8. 79 Create a J1 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 Circuit Window In Network View

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

Table 9-1 Cisco ONS 15454 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 network span; 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.)

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 may flow on a protect path.

Network spans are in one of two states: up or down. On CTC circuit and network maps, up spans are displayed as green lines, and down spans are displayed as gray lines. If a failure occurs on a network span during a CTC session, the span remains in 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 display on the network map.

Subsequently, circuits routed on a network span that goes down will display as ACTIVE during the current CTC session, but they will display as INCOMPLETE to users who log in after the span failure.

UPGRADABLE

A TL1-created circuit or a TL1-like CTC-created circuit is complete and has upgradable cross-connects. A complete path from source to destination(s) exists. You can upgrade the circuit using the "417 Upgrade TL1 Cross-Connects to CTC Circuits" procedure.

INCOMPLETE_UPGRADABLE

A TL1-created circuit or a TL1-like CTC-created circuit with upgradable cross-connects is missing a cross-connect, and a complete path from source to destination(s) does not exist. The circuit cannot be upgraded until missing cross-connects are in place.

NOT_UPGRADABLE

A TL1-created circuit or a TL1-like CTC-created circuit is complete but has at least one non-upgradable cross-connect. UPSR_HEAD, UPSR_EN, UPSR_DC, and UPSR_DROP cross-connects are not upgradable, so all unidirectional path protection configuration circuits created with TL1 are not upgradable.

INCOMPLETE_NOT_UPGRADABLE

A TL1-created circuit or a TL1-like CTC-created circuit with one or more non-upgradable cross-connects is missing a connection or circuit span (network link); a complete path from source to destination(s) does not exist.


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 Cisco ONS 15454 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 or by using the TL1 RTRV-COND command. VT 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. STS 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 or by using the TL1 RTRV-COND command.

The Monitors tab displays ports that you can use to monitor the circuit.


Note The Monitor tab is only available when the circuit has an ACTIVE status.


Step 7 On the Monitors tab, choose the monitor source port. The monitor circuit will display traffic coming into the node at the port you choose.


Note In Figure 9-5, you would choose either the DS1-14 card (to test circuit traffic entering Node 2 on the DS1-14) or the OC-N card at Node 1 (to test circuit traffic entering Node 1 on the OC-N card).


Step 8 Click Create Monitor Circuit.

Step 9 In the Circuit Destination section of the Circuit Creation wizard, choose the destination node, slot, port, STS, VT, or DS1 for the monitored circuit.


Note In the Figure 9-5 example, the monitor circuit destination is Port 2 on the EC1-12 card.


Step 10 Click Next.

Step 11 On the Circuit Routing Preferences panel, review the monitor circuit information. If you want the monitor circuit routed on a BLSR protection channel, click Protection Channel Access.

Step 12 Click Finish.

Step 13 On the Edit Circuit window, click Close. The new monitor circuit appears on the Circuits tab.

Figure 9-5 shows a sample monitor circuit setup. VT1.5 traffic is received by Port 1 of the EC1-12 card at Node 1. To monitor the VT1.5 traffic, test equipment is plugged into Port 2 of the EC1-12 card and a monitor circuit to Port 2 is provisioned in CTC. (Circuit monitors are one-way.) This example assumes circuits have been created.

If neither port is on a transmit/receive card, you will not be able to complete this procedure. If one port is on a transmit/receive card and the other is on a receive-only card, you can set up the transmit string at the transmit/receive port and the receive string at the receive-only port, but you will not be able to transmit in both directions.

Step 3 Choose the STS circuit you want to trace, then double-click it (or click Edit).

Step 4 On the Edit Circuit window, click the Show Detailed Map check 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 (the square on the left or right of the source node icon) and choose Edit J1 Path Trace (port) from the shortcut menu. Figure 9-6 shows an example.

Figure 9-6 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 the 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 detailed circuit map, (Figure 9-6) 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 the 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 pull-down menu:

Auto—The first string received from the source port is automatically provisioned as the current expected string. An alarm is raised when a string that differs from the baseline is received.

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

b. If you set the Path Trace Mode field 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 and RDI if TIM-P is detected check box if you want to suppress the alarm indication signal (AIS) and RDI 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.

d. (Check box visibility depends on card selection) Click the Disable AIS on C2 Mis-Match check box if you want to suppress the Alarm Indication Signal when a C2 mis-match occurs.

e. 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 9-6) 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 pull-down menu:

Auto—Uses the first string received from the port at the other path trace 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 the Path Trace Mode field 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 and RDI if TIM-P is detected check box if you want to suppress the alarm indication signal (AIS) and RDI 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. (Check box visibility depends on card selection) Click the Disable AIS on C2 Mis-Match check box if you want to suppress the Alarm Indication Signal when a C2 mis-match occurs.

f. Click Apply.

Step 9 After you set up the path trace, the received string is displayed in the Received field on the path trace setup window. Figure 9-7 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 if the Path Trace Mode field is set to Auto or Manual.

Step 10 Click Close.

Figure 9-7 Setting Up a Path Trace

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 9-8 shows an example.

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 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 OC-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 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 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 OC-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 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 the Path Trace Mode field to Auto, skip this step.

Step 8 Click Apply, then click Close.
