On Cisco IOS, I'm looking at moving from SNMP v1/2 to v3, which means separate user/password credentials instead of just community strings.
Is it possible to have those user credentials pulled from, and authenticated against, a TACACS or RADIUS server? Or am I stuck statically adding them to the configuration of every switch and router?
I'm sorry, but from what I ever see and read, it's not possible at the moment.
