aaa tacacs+ backup line

ozlemduran — Sun, 10 Mar 2019 14:40:01 GMT

hi,

I am using aaa for tacacs+ authentication on my routers but my tacacs+ server is taking usernames from LDAP. If LDAP goes down my authentication is failing. So I need a backup configuration for line vty 4 like

"aaa authentication login test line"

"login authentication test"

But line searching "enable" password from tacacs server...

I want that "line must use local enable password"

Hello Ozlem,

If the LDAP server fails then router will not fall back to local database unlike if ACS fails. The reason is that information is not propogated to the router. You can have backup LDAP server defined on the ACS though for fall back on ACS side.

Thanks,
