The following table describes the items in the previous figure.
Item Description
IP Address/Host
Name The IP address or host name of the RADIUS server. Host names must
be resolvable by DNS and are composed of a series of labels sepa-
rated by dots.
Server Name The name of the RADIUS server. RADIUS authentication servers that
are configured with the same name are members of the same named
RADIUS server group. RADIUS servers in the same group serve as
backups for each other.
Port Number The UDP port on the RAIDUS authentication server to which the local
RADIUS client sends request packets.
Secret The shared secret text string used for authenticating and encrypting all
RADIUS communications between the RADIUS client on the device
and the RADIUS server. The secret specified in this field must match
the shared secret configured on the RADIUS server.
Server Type Indicates whether the server is the Primary or a Secondary RADIUS
authentication server. When multiple RADIUS servers have the same
Server Name value, the RADIUS client attempts to use the primary
server first. If the primary server does not respond, the RADIUS client
attempts to use one of the backup servers within the same named
server group.
Message Authenti-
cator Indicates whether the RADIUS server requires the Message Authenti-
cator attribute to be present. The Message Authenticator adds protec-
tion to RADIUS messages by using an MD5 hash to encrypt each
message. The shared secret is used as the key, and if the message
fails to be verified by the RADIUS server, it is discarded.

Access-Reply/Access-Challenge and the Access-Request that

This number does not include retransmissions.

and invalid packets, that were received from the server.
