1.3. Remote authentication of administrator

Switch administrators can be saved in loca database and also in RADIUS/TACACS+ server.

The user is authenticated to RADIUS/TACACS+ server through RADIUS/TACACS+ protocol.

After authentication, user’s default privilege is normal user. Only when there is Service-Type

field in authentication accepting packet the value of which is Administrative, user’s privilege is

administrator.

If it is TACACS+ remote authentication, when the authorization is not used, the privilege after

authentication is administrator; when the authorization is used, the privilege after

authentication is determined by the replied priv_lvl from remote server, if there is no reply, it is

administrator; if the authorization fails, it is normal user.

Caution: Admin user only supports local database authentication.

1.3.1. Start RADIUS/TACACS+ remote authentication

Use following command in globa configuration mode:

muser { local | { radius radiusname { pap | chap } [ local ] } }|{tacacs+ [author] [account] [local]}

It can be configured to authenticate only by RADIUS/TACACS+ remote authentication or by

local database authentication after no response of RADIUS/TACACS+ server caused by failing

connection.

The accounting of TACACS+ is from the beginning to the end.
