Configuring System Message Logging
Beginning in privileged EXEC mode, follow these steps to enable configuration logging:
Command
Step 1
configure terminal
Step 2
archive
Step 3
log config
Step 4
logging enable
Step 5
logging size entries
Step 6
end
Step 7
show archive log config
This example shows how to enable the configuration-change logger and to set the number of entries in
the log to 500.
Switch(config)# archive
Switch(config-archive)# log config
Switch(config-archive-log-cfg)# logging enable
Switch(config-archive-log-cfg)# logging size 500
Switch(config-archive-log-cfg)# end
This is an example of output for the configuration log:
Switch# show archive log config all
