How to log SNMP auth fail event on "show log"

[owen75522]

How can i log SNMP auth failure on C2960X and C9300 ?

I have received trap by configure "snmp-server enable traps snmp authentication"

but i can't see more details (community, client ip ... etc) with "show log".

@owen75522  I would be interrested in the answer to the above question too. Have you found a solution to it by any chance?

There is logging snmp-authfail which Icurrently use and it works well , but that will be obsolete soon.

Anyone else having an idea?

I thought of debug commands, but I'm not sure which commands.

Thanks.
