Use Secret in Checksum
Some RADIUS servers calculate packet validation checksums using both the
secret value and the packet data. Earlier RADIUS servers typically do not.
Check the documentation for your RADIUS server to determine whether this
parameter should be set.
• If checked, packet checksums will be calculated using both the data and
the checksum.
Secondary Server
The device may be configured to use a secondary server if the primary server
cannot be contacted.
• If checked, a secondary server can be configured and will be used in the
event the primary server cannot be contacted.
Secondary Server IP Address
The device will attempt to contact this RADIUS server if the primary server
does not respond after the configured number of primary server retries. The
address should be entered in dotted-decimal notation (i.e. 198.238.41.7).
Secondary Server Retries
The device will try to resend a packet if the secondary RADIUS server
doesn’t acknowledge it within a timeout period. The timeout period for
packets 1 through 10 is (in seconds): 1, 1, 2, 2, 3, 3, 4, 4, 5, 5.
Possible values range between 1 and 10 with a default of 5.
Use Secret in Checksum

secret value and the packet data. Earlier RADIUS servers typically do not.
Check the documentation for your RADIUS server to determine whether this
parameter should be set.
• If checked, packet checksums will be calculated using both the data and
the checksum.
Secret
The secret is the shared secret used by the device and RADIUS server to vali-
date packets exchanged between them. This secret must match the client
secret configured in the RADIUS server. It can be from 1 to 31 ASCII char-
acters in length.
