Parameters
offline-detect offline-detect-value: Specifies the offline detect timer in the range of 60 to 65535, in
seconds.
quiet quiet-value: Specifies the quiet timer in the range of 1 to 3600, in seconds.
server-timeout server-timeout-value: Specifies the server timeout timer in the range of 100 to 300,
in seconds.
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 idle. If a user connection has been idle within the interval, the device
logs the user out and stops accounting for the user.
• 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.
• 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.
Examples
# Set the server timeout timer to 150 seconds.
