Chapter 2 Alarm Troubleshooting
2.7.124 FE-IDLE
2.7.124 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 DS-3 signal in C-bit framing
mode.
Clear the FE-IDLE Condition
Step 1 To troubleshoot the FE condition, determine which node and card link directly to the card reporting the
FE condition. For example, an FE condition on a card in Slot 12 of Node 1 could relate to a main alarm
from a card in Slot 6 of Node 2.
Step 2 Log into the node that links directly to the card reporting the FE condition.
Step 3 Clear the main alarm by clearing the protection switch. See the “2.9.2 Protection Switching, Lock
Initiation, and Clearing” section on page 2-262 for 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.
2.7.125 FE-LOCKOUTOFPR-SPAN
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Object: OCN
The Far-End Lock Out of Protection Span condition occurs when a BSLR span is locked out of the
protection system from a far-end node using the Lockout Protect Span command. This condition is only
seen on the network view Conditions tab and is accompanied by LKOUTPR-S. The port where the
lockout originated is marked by an “L” on the network view detailed circuit map.
Clear the FE-LOCKOUTOFPR-SPAN Condition
Step 1 To troubleshoot an FE condition, determine which node and card link directly to the card reporting the
FE alarm. For example, an FE-AIS condition from the OC-48 card in Slot 12 of Node 1 could link to the
main AIS condition from an OC-48 card in Slot 6 of Node 2.
Step 2 Log into the node that links directly to the card reporting the FE condition.
Step 3 Ensure there is no lockout set. Complete the “Clear a BLSR External Switching Command” procedure
on page 2-269.
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.
