Configuring Authentication Server Hosts

The Authentication Server is a remote device connected to the same network as the Client and Authenticator. Users are authenticated using either RADIUS or TACACS+, and must be authenticated by the server before attaining network access. To define the Authentication Server information:

1.Click Security > Access Authentication Control> Authentication Server Host. The Authentication Server Host Page opens:

	Figure 5-18. Authentication Server Host Page
The Authentication Server Host Page contains the following fields:
Field	Description
IP Address	Defines the IP address of the RADIUS or TACACS+ server authenticating network users.
Protocol	Indicates the authentication protocol used to authenticate network users. The possible
	field values are:
	RADIUS — Indicates that network users are authenticated via a RADIUS server.
	TACACS+ — Indicates that network users are authenticated via a TACACS+ server.
Key	Defines the key used to authenticate network users. The key may contain up to 128
	characters
Priority	Defines the priority assigned to the server. The field range is First -Third, where Third is
	the lowest priority and First is the highest priority.
Port (1-65535)	The port number for authentication requests. The host is not used for authentication if set
	to 0. If unspecified, the Radius port number defaults to 1812, TACACS+ port number
	defaults to 49.
Timeout (1-30secs)	Indicates the amount of time that passes, in which no authentication activity occurs, after
	which the authentication session times out.
Retransmit (1-10 times)	Indicates the number of times the port attempts to re- authenticate a timed out session.
