NOTE: More than one authentication protocol can be run on the same physical server host but, remember
that TACACS/XTACACS/TACACS+ are separate entities and are not compatible with each other.
Login Method Lists Settings
User-defined or default Login Method List of authentication techniques can be configured for users logging on to the
Switch. The sequence of techniques implemented in this command will affect the authentication result. For example, if
a user enters a sequence of techniques, for example TACACS - XTACACS- local, the Switch will send an
authentication request to the first TACACS host in the server group. If no response comes from the server host, the
Switch will send an authentication request to the second TACACS host in the server group and so on, until the list is
exhausted. At that point, the Switch will restart the same sequence with the following protocol listed, XTACACS. If no
authentication takes place using the XTACACS list, the local account database set in the Switch is used to
authenticate the user. When the local method is used, the privilege level will be dependent on the local account
privilege configured on the Switch.
Successful login using any of these techniques will give the user a "User" privilege only. If the user wishes to upgrade
his or her status to the administrator level, the user must use the Enable Admin window, in which the user must enter
a previously configured password, set by the administrator.

Description
The IP address of the remote server host to add.
The protocol used by the server host. The user may choose one of the following:
TACACS - Enter this parameter if the server host utilizes the TACACS protocol.
XTACACS - Enter this parameter if the server host utilizes the XTACACS protocol.
TACACS+ - Enter this parameter if the server host utilizes the TACACS+ protocol.
RADIUS - Enter this parameter if the server host utilizes the RADIUS protocol.
Authentication key to be shared with a configured TACACS+ or RADIUS servers only.
Specify an alphanumeric string up to 254 characters.
Enter a number between 1 and 65535 to define the virtual port number of the
authentication protocol on a server host. The default port number is 49 for
TACACS/XTACACS/TACACS+ servers and 1813 for RADIUS servers but the user may
set a unique port number for higher security.
Enter the time in seconds the Switch will wait for the server host to reply to an
authentication request. The default value is 5 seconds.
Enter the value in the retransmit field to change how many times the device will resend an
authentication request when the TACACS server does not respond.
