IP Address

The IP address of the remote server host the user wishes to add.

Port (1-65535) 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.

Protocol

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.

Timeout (1-255)

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.

Key

Authentication key to be shared with a configured TACACS+ or RADIUS servers only. Specify

an alphanumeric string up to 254 characters.

Retransmit (1-255)

Enter the value in the retransmit field to change how many times the device will resend an

authentication request when the server does not respond.

Click Apply to add the server host. Entries will be displayed in the table on the lower half of this window.

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

This command will configure a user-defined or default Login Method List of authentication techniques 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 dependant on the local account

privilege configured on the Switch.

When the user logins to the device successfully through TACACS/XTACACS/TACACS+server or none method, the

“user” privilege level is assigned only. If the user wants to get admin privilege level, the user must use the Enable

Admin window to promote his privilege level. (See the Enable Admin part of this section for more detailed

information.) But when the user logins to the device successfully through RADIUS server or local method, 3 kinds of

privilege levels can be assigned to the user and the user cannot use the Enable Admin window to promote to admin

privilege level.
