Nexus Accounting Log

Perhaps another trivial post, but if you don’t know about it, you might find it extremely useful.

Cisco NX-OS has an on-device log file of the exec level configuration commands entered successfully. Obviously similar informational can be obtained from the TACACS logs, but there is a certain benefit in having directly on CLI.

The command is:

#show accounting log

Here is some sampled output:

Nexus#show accounting log | last 35 | i SUCCESS

Fri Mar  2 13:57:23 2012:type=update:id=10.5.0.1@pts/33:user=bruce:cmd=copy running-config startup-config (SUCCESS)

Obviously the usual NX-OS CLI pipe operands apply to limit the display to exactly what is required or needed.

HTH, let me know if you have used this…
