Authentication Server Hosts

This window will set user-defined Authentication Server Hosts for the TACACS / XTACACS / TACACS+ / RADIUS security protocols on the Switch.When a user attempts to access the Switch with Authentication Policy enabled, the Switch will send authentication packets to a remote TACACS / XTACACS / TACACS+ / RADIUS server host on a remote host.The TACACS / XTACACS / TACACS+ / RADIUS server host will then verify or deny the request and return the appropriate message to the Switch. More than one authentication protocol can be run on the same physical server host but, remember that TACACS / XTACACS / TACACS+ / RADIUS are separate entities and are not compatible with each other.The maximum supported number of server hosts is 16.

		XTACACS – Enter this parameter if the server host utilizes the XTACACS protocol.
		TACACS+ – Enter this parameter if the server host utilizes the TACACS+ protocol.
	Port (1-65535)	RADIUS – Enter this parameter if the server host utilizes the RADIUS protocol.
		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
	Timeout (1-255)	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
	Retransmit (1-255)	default value is 5 seconds.
		Enter the value in the retransmit field to change how many times the device will resend an authentication
	Key	request when the TACACS server does not respond.
