Usage guidelines
MAC authentication uses the following timers:
•
Offline detect timer—Sets the interval that the device waits for traffic from a user before the
device regards the user as idle. The device logs off the user and requests to stop accounting for
the user after the timer expires. This timer takes effect only when the MAC authentication offline
detection feature is enabled.
After you set the offline detect timer, assign the same value to the MAC address aging timer by
using the mac-address timer command. This operation prevents a MAC authenticated user
from being offline within the offline detect timer due to MAC address entry expiration.
•
Quiet timer—Sets the interval that the device must wait before the device can perform MAC
authentication for a user that has failed MAC authentication. All packets from the MAC address
are dropped during the quiet time. This quiet mechanism prevents repeated authentication from
affecting system performance.
•
Periodic MAC reauthentication timer—Sets the interval at which the device reauthenticates
online MAC authentication users on a port if the port is enabled with periodic MAC
reauthentication. A change to the global periodic reauthentication timer applies to online users
only after the old timer expires.
•
Server timeout timer—Sets the interval that the device waits for a response from a RADIUS
server before the device regards the RADIUS server unavailable. If the timer expires during
MAC authentication, the user cannot access the network.
