Release R.11.24 through R.11.25 Enhancements
■ Enhancement (PR_0000011010) — Support is added for Hitless MAC Authentication 
Reauth. For more information, see “Hitless MAC Authentication Reauth” on page 52.
Hitless MAC Authentication Reauth
The reauthentication procedure has been changed to allow an authenticated client to remain 
authenticated while reauthentication occurs. Previously, after the user-configured authentication 
period expired, the client was deauthenticated while the RADIUS server was queried. This resulted 
in a small delay during which frames were dropped. 
Any changes in RADIUS attributes are applied after authentication is successful. If authentication is 
not successful, the client is disconnected. 
Release R.11.24 through R.11.25 Enhancements 
No enhancements, software fixes only.
Syntax: aaa port-access mac-based <port-list> [reauth-period <0-9999999>]
Specifies the time period, in seconds, after which the switch must reauthenticate 
with the RADIUS server. When set to 0 (zero), reauthentication is disabled.
Default: 0 seconds (disabled)
