Configuring TACACS+ Server Hosts

To access a remote TACACS+ server, you must configure the IPv4 or IPv6 address or the hostname for the
TACACS+ server on the Cisco Nexus 5000 Series switch. All TACACS+ server hosts are added to the default
TACACS+ server group.You can configure up to 64 TACACS+ servers.
If a preshared key is not configured for a configured TACACS+ server, a warning message is issued if a global

that server.
