TACACS+ Authentication
Configuring TACACS+ on the Switch
Messages Related to TACACS+ 
Operation
The switch generates the CLI messages listed below. However, you may see 
other messages generated in your TACACS+ server application. For informa-
tion on such messages, refer to the documentation you received with the 
application.
Operating Notes
If you configure Authorized IP Managers on the switch, it is not 
necessary to include any devices used as TACACS+ servers in the 
authorized manager list. That is, authentication traffic between a 
TACACS+ server and the switch is not subject to Authorized IP 
Manager controls configured on the switch. Also, the switch does not 
attempt TACACS+ authentication for a management station that the 
Authorized IP Manager list excludes because, independent of 
TACACS+, the switch already denies access to such stations.
CLI Message
Meaning
Connecting to Tacacs server
The switch is attempting to contact the TACACS+ server identified in the switch’s 
tacacs-
server 
configuration as the first-choice (or only) TACACS+ server.
Connecting to secondary 
Tacacs server
The switch was not able to contact the first-choice TACACS+ server, and is now 
attempting to contact the next (secondary) TACACS+ server identified in the switch’s 
tacacs-server
 configuration.
Invalid password
The system does not recognize the username or the password or both. Depending on the 
authentication method (tacacs or local), either the TACACS+ server application did not 
recognize the username/password pair or the username/password pair did not match the 
username/password pair configured in the switch.
No Tacacs servers 
responding
The switch has not been able to contact any designated TACACS+ servers. If this message 
is followed by the Username prompt, the switch is attempting local authentication.
Not legal combination of 
authentication methods
For console access, if you select tacacs as the primary authentication method, you must 
select local as the secondary authentication method. This prevents you from being locked 
out of the switch if all designated TACACS+ servers are inaccessible to the switch.
Record already exists
When resulting from a 
tacacs-server host
 <ip addr> command, indicates an attempt to 
enter a duplicate TACACS+ server IP address.
