show monitor event-trace
CF-761
Cisco IOS Configuration Fundamentals Command Reference
July 2008
Usage Guidelines Use the show monitor event-trace command to display trace message information.
The trace function is not locked while information is being displayed to the console, which means that
new trace messages can accumulate in memory. If entries accumulate faster than they can be displayed,
some messages can be lost. If this happens, the show monitor event-trace command will generate a
message indicating that some messages might be lost; however, messages will continue to display on the
console. If the number of lost messages is excessive, the show monitor event-trace command will stop
displaying messages.
Use the bfd keyword for the component argument to display trace messages relating to the BFD feature.
Use the cfd keyword for the component argument to display trace messages relating to the crypto fault
detection feature. This keyword displays the contents of the error trace buffers in an encryption data path.
Examples
IPC Component Example
The following is sample output from the show monitor event-trace component command for the
interprocess communication (IPC) component. Notice that each trace message is numbered and is
followed by a time stamp (derived from the device uptime). Following the time stamp is the
component-specific message data.
Router# show monitor event-trace ipc
3667: 6840.016:Message type:3 Data=0123456789
3668: 6840.016:Message type:4 Data=0123456789
3669: 6841.016:Message type:5 Data=0123456789
3670: 6841.016:Message type:6 Data=0123456

Use the show monitor event-trace bfd all command to display logged messages for important BFD
events in the recent past. The following trace messages show BFD session state changes:
Router# show monitor event-trace bfd all
3d03h: EVENT: Session [172.16.10.2,172.16.10.1,Fa6/0,1], event Session
create, state Unknown -> Fail
3d03h: EVENT: Session [172.16.10.2,172.16.10.1,Fa6/0,1], state Fail -> Down
(from LC)
3d03h: EVENT: Session [172.16.10.2,172.16.10.1,Fa6/0,1], state Down -> Init
