Chapter 2 Alarm Troubleshooting
2.7.199 LOCKOUT-REQ
Step 5 Recreate the circuit using the procedure in the “Create Circuits and VT Tunnels” chapter in the
Cisco ONS 15454 Procedure Guide.
Step 6 If the alarm 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 in order to report a Service-Affecting (SA)
problem.
2.7.199 LOCKOUT-REQ
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Objects: EQPT, OCN, STSMON, VT-MON
DWDM Logical Objects: 2R, ESCON, FC, GE, ISC, TRUNK
The Lockout Switch Request on Facility or Equipment condition occurs when a user initiates a lockout
switch request for an OC-N port in a 1+1 facility protection group. This can be accomplished by locking
traffic onto the working port with the LOCK ON command (thus locking it off the protect port), or
locking it off the protect port with the LOCK OUT command. In either case, the protect port will show
“Lockout of Protection,” and the Conditions window will show the LOCKOUT-REQ condition.
A lockout prevents protection switching. Clearing the lockout again allows protection switching and
clears the LOCKOUT-REQ condition.
Clear the LOCKOUT-REQ Condition
Step 1 Complete the “Clear a Lock-On or Lockout Command” procedure on page 2-264.
Step 2 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.
2.7.200 LOF (BITS)
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
SONET Logical Object: BITS
The Loss of Frame (LOF) BITS alarm occurs when a port on theTCC2/TCC2P BITS input detects an
LOF on the incoming BITS timing reference signal. LOF indicates that the receiving ONS 15454 has
lost frame delineation in the incoming data.
Note The procedure assumes that the BITS timing reference signal is functioning properly. It also assumes the
alarm is not appearing during node turn-up.
Clear the LOF (BITS) Alarm
Step 1 Verify that the line framing and line coding match between the BITS input and the TCC2/TCC2P:
a. In node or card view, note the slot and port reporting the alarm.
