Description

This set of commands is used to specify a radius server that the router will use for authentication. The radius-server host command allows you to specify which radius server to use, either by hostname or IP address. You can define more than one radius server; the router attempts to contact the servers in the order that you specify.

The radius-server key command specifies the encryption string to be used for communication with the radius server. Obviously, this string must match the setting on the radius server. If you use multiple servers, they must all share the same key.

The retransmit and timeout forms of this command specify the number of times the router searches the list of radius servers before giving up, and the amount of time that it will wait for any given server to reply before retrying.
