Description
Using host command, you can add a TACACS+ server into a TACACS+ server group
by specifying its IP address as well as specifing it as the primary AAA server. Using
undo host command, you can delete a TACACS+ server from a TACACS+ server
group by specifying its IP address or you can disable it as the AAA primary server.
By default, no TACACS+ server is configured.
A server group allows of a maximum of five TACACS+ servers.
You can use the parameters authen-primary, author-primary, or account-primary
to specify the current configured TACACS+ server as the specified primary
authentication, authorization, or accounting server. If none of the servers in a sever
group has been specified as the primary server, the first one will be the primary
server.
If a primary server has been specified, and if the current AAA server is a standby
server, the switch interval specified by the timer quiet command in hwtacacs view will
be used to perform the standby/primary switchover operation. Otherwise, no switch
will be performed.
