9. Select the Re-authentication checkbox to force a periodic re-authentication with the NAC server.
Periodic repetition of the authentication process provides ongoing security for currently authorized connections. Define
an interval between 30 and 65535 seconds.
10.Refer to the Advanced field to define the authentication protocol used with the NAC Server.
NAC Server Address
Enter the IP address of the primary and secondary NAC server.
NAC Server Port
Enter the TCP/IP port number for the primary and secondary server. The default port is 1812.
NAC Shared Secret
Provide a shared secret (password) for user credential authentication with the primary or
secondary NAC server.
Server Timeout
Enter a value (between 1 and 300 seconds) to indicate the number of elapsed seconds
causing the switch to time out on a request to the primary or secondary NAC server.
Server Retries
Enter a value between 1 and 100 to indicate the number of times the switch attempts to reach
the primary or secondary server before giving up.
CAUTION: The server’s Timeout and Retries should be less than what is defined for an
MU’s timeout and retries. If the MU’s time is less than the server’s, a fall back to the
secondary server will not work.
Accounting Server

accounting data source. The default port is 1813.

PAP
PAP - Password Authentication Protocol sends a username and password over a network to
a server that compares the username and password to a table of authorized users. If the
username and password are matched in the table, server access is authorized.
CHAP
CHAP is an encrypted authentication method based on Microsoft's challenge/response
authentication protocol.
DSCP/TOS
Optionally mark packets with a DiffServ CodePoint (DSCP) in its header. The DSCP value is
stored in the first 6 bits of the Type of Service (ToS) field that is part of the standard IP header.
The DCSP values are associated with a forwarding treatment called
Per Hop Behaviors (PHB).
Service can be provisioned (if necessary) by assigning a DCSP point code from 1 - 6.
