SNMP v3 users not shown in running-config
Ralf sent me a SNMPv3 question:
If I create a SNMPv3 user which has a password (snmp-server user userthree groupthree v3 auth md5 user3passwd), this user does not appear in the running- or startup-config. Cisco even documents this if you know what to look for.Like certificates, the SNMPv3 users are stored in private-config and thus never appear in the router configuration. If you want to have a backup of the user data, create a text file on one of your NMS servers, add SNMPv3 usernames and passwords in the text file and use the copy somewhere running-config to configure SNMPv3 users on the routers.
I strongly suspect (although I did not test this) that these users are also missing from configuration exported to TFTP servers. What would be the recommended way to make usable config backups of routers with such users?
