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
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.

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.
