Hi Seong,
There is no fallback authentication in F5. You either authenticate with TACACS or Locally.
If the user (abc123) is part of tacacs remote role, he will get authenticated with TACACs authentication, there is no fallback to getting locally authenticated when TACACS servers are unreachable/issues.
If the user (xyz789) is a localuser, he will get authenticated locally, it will not goto TACACS for authentication even if the user (xyz789) is having some TACACS remote role.
