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 OCHNC.

STS, VT, VTT (VT tunnel), VAP (VT aggregation point), STS-v (STS VCAT circuit), and VT-v (VT VCAT circuit) are not applicable for ANSI DWDM nodes. HOP (high-order circuit), LOP (low-order circuit), VCT (VC low-order tunnel), VCA (VC low-order aggregation point), HOP_v (high-order virtual concatenated [VCAT] circuit), or LOP_v (low-order VCAT circuit) are not applicable for ETSI DWDM nodes.

•Size—Circuit size. 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. VT, STS, and VCAT circuits are not applicable to ANSI DWDM nodes. VC12, VC3, VC4, and VCAT circuits are not applicable to ETSI DWDM nodes.

•OCHNC Wlen—For OCHNCs, the wavelength provisioned for the optical channel network connection. See Table 6-3 for a list of channels and wavelengths.

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

•OCHNC Dir—The direction of the OCHNC, either East to West or West to East. If the direction is West to East, the channel exits from the node through the LINE-TX port of the OSC-CSM or OPT-BST card (typically in Slot 17). If the direction is East to West, the channel exits from the node through the LINE-TX port of OSC-CSM or OPT-BST card (typically in Slot 1).

•Protection—The type of circuit protection. See Table 6-1 for a list of protection types.

•Status—The circuit status. Table 6-2 lists the circuit statuses that can appear.

•Source—The circuit source in the format: node/slot/port "port name" (the port name will appear in quotes).

•Destination—The circuit destination in same format as the circuit source. STSs, VTs, VCs, and tributary units are not applicable to DWDM nodes.

•# of VLANS—The number of VLANs used by an Ethernet circuit. VLANs are not applicable to DWDM nodes.

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

•State—The circuit service state, which is an aggregate of its cross-connects. For ANSI, the service states are IS, OOS, or OOS-PARTIAL. For ETSI, the service states are Unlocked, Locked, or Locked-partial. For more information about ANSI and ETSI service states, see the "DWDM Enhanced State Model."

–IS/Unlocked—All cross-connects are in service and operational.

–OOS/Locked—All cross-connects are Out-of-Service and Management, Maintenance (OOS-MA,MT) and/or Out-of-Service and Management, Disabled (OOS-MA,DSBLD) for ANSI or Locked-enabled,maintenance and/or Locked-enabled,disabled for ETSI.

–OOS-PARTIAL/Locked-partial—At least one cross-connect is In-Service and Normal (IS-NR [ANSI]) or Unlocked-enabled (ETSI) and others are out-of-service.

Table 6-1 Circuit Protection Types 

Protection Type
Description

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 splitter protection.

Unprot (black)

A circuit with a source and destination on different nodes is not protected.

N/A

A circuit with connections on the same node is not protected.

Unknown

A circuit has a source and destination on different nodes and communication is down between the nodes. This protection type appears if not all circuit components are known.

Definition/Activity

CREATING

CTC is creating a circuit.

DISCOVERED

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.

PARTIAL

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 PARTIAL. However, a PARTIAL 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 are shown as green lines, and down spans are shown 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 DISCOVERED during the current CTC session, but they will appear as PARTIAL to users who log in after the span failure.

The PARTIAL status does not appear for OCHNC circuit types.

DISCOVERED_TL1

A TL1-created circuit or a TL1-like CTC-created circuit is complete. A complete path from source to destination(s) exists.

This status does not appear for OCHNC circuit types.

PARTIAL_TL1

A TL1-created circuit or a TL1-like CTC-created circuit is missing a cross-connect, and a complete path from source to destination(s) does not exist.

This status does not appear for OCHNC circuit types.

This service state does not interrupt traffic flow, but alarm reporting is suppressed 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. Use the OOS-MA,MT/Locked-enabled,maintenance service state for testing or to suppress alarms temporarily. Change to the IS-NR/Unlocked-enabled or OOS-AU,AINS/Unlocked-disabled,automaticInService service states when testing is complete.

•IS, AINS (ANSI) or Unlocked,automaticInService (ETSI)—Places the port in the OOS-AU,AINS/Unlocked-enabled,automaticInService service state. In this service state, alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. After the soak period passes, the port changes to IS-NR/Unlocked-enabled. 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.

For more information about service states, refer to "DWDM Enhanced State Model."

Step 4 If you set the Admin State to IS-AINS/Unlocked,automaticInService, set the soak period time in the AINS Soak field. This is the amount of time that the port will stay in the OOS-AU,AINS/Unlocked-enabled,automaticInService service state after a signal is continuously received. When the soak period elapses, the port changes to the IS-NR/Unlocked-enabled service state.

Step 5 Click Apply. The new port service state appears in the Service State column.

Step 6 As needed, repeat this task for each port.

•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.

Step 6 In the Section Trace String Size area, click 1 byte or 16 byte.

Step 7 In the New Transmit String field, enter the string that you want to transmit. Enter a string that makes the destination port easy to identify, such as the node IP address, node name, or another string. If the New Transmit String field is left blank, the J0 transmits a string of null characters.

Step 8 If you set the Section Trace Mode field to Manual, enter the string that the destination port should receive from the source port in the New Expected String field. If you set Section Trace Mode to Auto, skip this step.

Step 9 Click the Disable AIS and RDI if TIM-P is detected check box if you want to suppress the alarm indication signal (AIS) and remote defect indication (RDI) when the STS Section Trace Identifier Mismatch Path (TIM-P) alarm appears. Refer to the Cisco ONS 15454 SONET and DWDM Troubleshooting Guide for descriptions of alarms and conditions.

Step 10 Click Apply.

Step 11 After you set up the section trace, the received string appears in the Received field. The following options are available:

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

•Click the Reset button to reread values from the port.

•Click Default to return to the section trace default settings (Section 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 Section Trace Mode field is set to Auto or Manual.

Stop. You have completed this procedure.
