Step 1 Navigate to the appropriate CTC view:

To view circuits for an entire network, from the View menu, choose Go to Network View.

To view circuits that originate, terminate, or pass through a specific node, from the View menu, choose Go to Other Node, then choose the node you want to search and click OK.

To view circuits that originate, terminate, or pass through a specific card, in node view, double-click the card containing the circuits you want to view.

Step 2 Click the Circuits tab. The Circuits tab shows the following information:

Circuit Name—Name of the circuit. The circuit name can be manually assigned or automatically generated.

Type—Circuit types are: HOP (high-order path circuit), LOP (low-order path circuit), VCT (VC low-order tunnel), VCA (VC low-order aggregation point), OCHNC (DWDM optical channel network connection), HOP_v (VCAT high-order circuit), or LOP_v (VCAT low-order circuit).

Size—Circuit size. High-order circuit sizes are VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, VC4-12c, VC4-16c, VC4-64c. Low-order circuits are VC12 and VC3. OCHNC sizes are Equipped not specific, Multi-rate, 2.5 Gbps No FEC (forward error correction), 2.5 Gbps FEC, 10 Gbps No FEC, and 10 Gbps FEC. High-order VCAT circuits are VC4-2v and VC4-4c-2v. Low-order VCAT circuits are VC3-2v.

OCHNC Wlen—For OCHNCs, the wavelength provisioned for the optical channel network connection. See Table 5-5 on page 5-19 for a list of channels and wavelengths.

Direction—The circuit direction, either two-way or one-way.

OCHNC Dir—For OCHNCs, the direction of the optical channel network connection, either east to west or west to west.

Protection—The type of circuit protection. See Table 11-1 for a list of protection types.

Table 11-1 Circuit Protection Types 

Protection Type
Description

N/A

Circuit protection is not applicable.

2F MS-SPR

The circuit is protected by a two-fiber multiplex section-shared protection ring (MS-SPRing).

4F MS-SPR

The circuit is protected by a four-fiber MS-SPRing.

MS-SPR

The circuit is protected by both a two-fiber and a four-fiber MS-SPRing.

SNCP

The circuit is protected by an SNCP.

SNCP-DRI

The circuit is protected by an SNCP dual-ring interconnection.

1+1

The circuit is protected by a 1+1 protection group.

Y-Cable

The circuit is protected by a transponder or muxponder card Y-cable protection group.

Splitter

The circuit is protected by the protect transponder (TXPP_MR_2.5G) splitter protection.

Protected

The circuit is protected by diverse SDH topologies, for example, an MS-SPRing and an SNCP, or an SNCP and a 1+1 protection group.

2F-PCA

The circuit is routed on a protection channel access (PCA) path on a two-fiber MS-SPRing; protection channel access circuits are unprotected.

4F-PCA

The circuit is routed on a protection channel access path on a four-fiber MS-SPRing; PCA circuits are unprotected.

PCA

The circuit is routed on a protection channel access path on both two-fiber and four-fiber MS-SPRings; PCA circuits are unprotected.

Unprot (black)

The circuit is not protected.

Unprot (red)

The circuit created as a fully protected circuit is no longer protected due to a system change, such as a traffic switch.

Unknown

The circuit protection types appear 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 appears as "unknown."


Status—The circuit status. Table 11-2 lists the circuit statuses that might appear.

Table 11-2 Cisco 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 network span, a complete path from source to destination(s) does not exist.

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, because 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 that 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 does not appear on the network map.

Subsequently, circuits routed on a network span that goes down appear as ACTIVE during the current CTC session, but they appear as INCOMPLETE to users who log in after the span failure. This status does not appear for OCHNC circuit types.


Source—The circuit source in the format: node/slot/port "port name" virtual_container/tributary_ unit_group/tributary_unit_group/virtual_container. (The port name appears in quotes.) Node and slot always appear; port "port name"/virtual_container/tributary_unit_group/tributary_unit group/virtual_container might appear, depending on the source card, circuit type, and whether a name is assigned to the port. If the circuit size is a concatenated size (VC4-2c, VC4-4c, VC4-8c, etc.) VCs used in the circuit are indicated by an ellipsis, for example, "VC4-7..9" (VCs 7, 8, and 9) or VC4-10..12 (VC 10, 11, and 12).

Destination—The circuit destination in same format (node/slot/port "port name" virtual_container/tributary_unit_group/tributary_unit_group/virtual_container) as the circuit source.

# of VLANS—The number of VLANS used by an Ethernet circuit with end points on E-Series Ethernet cards in single card or multicard mode.

# of Spans—The number of inter-node links that compose the circuit. Right-clicking the column displays a shortcut menu from which you can choose to show or hide circuit span detail.

State—The circuit state. Table 11-3 lists the circuit states that might appear.

Table 11-3 Cisco ONS 15454 SDH Circuit States 

State
Definition

IS

In service; able to carry traffic.

OOS

Out of service; unable to carry traffic. This status does not appear for OCHNC circuit types.

OOS-AINS

Out of service, auto in service; alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether or not their alarms are reported, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command. VC low-order circuits in OOS-AINS generally switch to IS when source and destination ports are IS, OOS_AINS, or OOS_MT regardless of whether a physical signal is present. VC high-order circuits in OOS-AINS switch to IS when a signal is received. This status does not appear for OCHNC circuit types.

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. This status does not appear for OCHNC circuit types.

Step 6 In 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 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.


Note It is not necessary to set the format (16 or 64 bytes) for the expected string; the path trace process automatically determines the format.


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.

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 and RDI on J2 TIM check box if you want to suppress the AIS and RDI when the LP-TIM alarm appears. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide for descriptions of alarms and conditions.

d. Click the Disable AIS on LO SLM check box if you want to suppress the AIS when the Low-Order Signal Label Mismatch (LO SLM) alarm appears. Refer to the Cisco ONS 15454 SDH 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 AIS when a C2 mismatch occurs.

f. Click Apply, then click Close.


Note It is not necessary to set the format (16 or 64 bytes) for the circuit destination expected string; the path trace process automatically determines the format.


Step 9 Provision the circuit source expected string:

a. In the Edit Circuit window (with Show Detailed Map chosen, see Figure 11-3) right-click the circuit source port and choose Edit Path Trace from the shortcut menu.

b. In 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 current expected 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 the Path Trace Mode field to Auto, skip this step.

d. Click the Disable AIS and RDI on J2 TIM check box if you want to suppress the AIS and RDI when the LP-TIM alarm appears. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide for descriptions of alarms and conditions.

e. Click the Disable AIS on LO SLM check box if you want to suppress the alarm indication signal when the LO SLM alarm appears. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide for descriptions of alarms and conditions.

f. (Check box visibility depends on card selection) Click the Disable AIS on C2 Mis-Match check box if you want to suppress the AIS when a C2 mismatch occurs.

g. Click Apply.


Note It is not necessary to set the format (16 or 64 bytes) for the circuit source expected string; the path trace process automatically determines the format.


Step 10 After you set up the path trace, the received string appears in the Received field on the path trace setup window. The following options are available:

Click Hex Mode to display path trace in hexadecimal format. The button name changes to ASCII Mode. Click it to return the path trace to ASCII format.

Click Reset 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 generates 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 11 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.

Step 12 Return to your originating procedure (NTP).
