MAC Authentication Timers
The following timers function in the process of MAC authentication:
z
Offline detect timer: At this interval, the switch checks to see whether an online user has gone
offline. Once detecting that a user becomes offline, the switch sends a stop-accounting notice to
the RADIUS server.
z
Quiet timer: Whenever a user fails MAC authentication, the switch does not initiate any MAC
authentication of the user during a period defined by this timer.
z
Server timeout timer: During authentication of a user, if the switch receives no response from the
RADIUS server in this period, it assumes that its connection to the RADIUS server has timed out
and forbids the user from accessing the network.
Quiet MAC Address
When a user fails MAC authentication, the MAC address becomes a quiet MAC address, which means
that any packets from the MAC address will be discarded simply by the switch until the quiet timer
expires. This prevents an invalid user from being authenticated repeatedly in a short time.
z
If the quiet MAC is the same as the static MAC configured or an authentication-passed MAC, then
the quiet function is not effective.
z
The S3100 series Ethernet switches support quiet MAC function on ports.
