MAC authentication timers
MAC authentication uses the following timers:
Offline detect timer—Sets the interval that the device waits for traffic from a user before it regards the user idle. If a user connection has been idle for two consecutive intervals, the device logs the user out and stops accounting for the user.
Quiet timer—Sets the interval that the device must wait before it can perform MAC authentication for a user who 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.
Server timeout timer—Sets the interval that the access device waits for a response from a RADIUS server before it regards the RADIUS server unavailable. If the timer expires during MAC authentication, the user cannot access the network.
