Chapter 2 Alarm Troubleshooting

2.7.82 FE-FRCDWKSWPR-SPAN

The Far End Forced Switch Back to Working—Span condition is raised on a far-end 1+1 protect port when it is Force switched to the working port.

Note WKSWBK-type conditions apply only to nonrevertive circuits.

Clear the FE-FRCDWKSWBK-SPAN Condition

Step 1 Complete the “Clear a 1+1 Force or Manual Switch Command” section on page 2-149for the far-end port.

If the condition does not clear, log into the Technical Support Website at

http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.7.82 FE-FRCDWKSWPR-SPAN

The FE-FRCDWKSWPR-SPAN condition is not used in the ONS 15310 platforms in this release. It is reserved for development.

2.7.83 FE-IDLE

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

SONET Logical Object: DS3

The Far End Idle condition occurs when a far-end node detects an idle far-end 15310-CL-CTX,

ONS 15310-MA DS1-28/DS3-EC1-3, or ONS 15310-MA DS1-84/DS3-EC1-3 card DS-3 signal in C-bit line type mode.

Clear the FE-IDLE Condition

Step 1 To troubleshoot the FE condition, determine which node and port link directly to the card reporting the FE condition.

Step 2 Log into the node that links directly to the port reporting the FE condition.

Step 3 Clear the main alarm by clearing the protection switch. See the “2.10.1 Protection Switching, Lock Initiation, and Clearing” section on page 2-147for commonly used traffic-switching procedures.

Step 4 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1-800-553-2447).

2.7.84 FE-LOCKOUTOFPR-SPAN

The FE-LOCKOUTOFPR-SPAN condition is not used in the ONS 15310 platforms in this release. It is reserved for development.
