Usage Guidelines RADIUS is a client/server authentication and authorization access protocol used by a NAS to

authenticate users attempting to connect to a network device. The NAS functions as a client, passing user

information to one or more RADIUS servers. The NAS permits or denies network access to a user based

on the response it receives from one or more RADIUS servers. RADIUS uses UDP for transport between

the RADIUS client and server.

You can configure a RADIUS key on the client and server. If you configure a key on the client, it must

be the same as the one configured on the RADIUS servers. The RADIUS clients and servers use the key

to encrypt all RADIUS packets transmitted. If you do not configure a RADIUS key, packets are not

encrypted. The key itself is never transmitted over the network.

host Specifies a RADIUS server. You can specify up to 5 servers.

hostname Hostname of the RADIUS server.

hostipaddr IP address of the RADIUS server.

primary (Optional) Sets the server as the primary server.

key Specifies the encryption key shared with the RADIUS servers.

keyword Text of the shared key (15 characters maximum).

retransmit Specifies the number of transmission attempts to an active server.

retries Number of transmission attempts for a transaction (1–3). The default is 2.

timeout Specifies the time to wait for a RADIUS server to reply. The range is 1 to

20 seconds.

seconds Wait time in seconds (1–20). The default is 5 seconds.
