Step Command Remarks
2. Configure the MAC
authentication user
account format.
• Use one MAC-based user account
for each user:
mac-authentication
user-name-format mac-address
[ { with-hyphen | without-hyphen }
[ lowercase | uppercase ] ]
• Use one shared user account for all
users:
mac-authentication
user-name-format fixed [ account
name ] [ password { cipher |
simple } password ]
Use either method.
By default, the device uses the
MAC address of a user as the
username and password for
MAC authentication. The MAC
address is in lower case without
hyphens.

Configuring 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 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 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 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.
To configure MAC authentication timers:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure MAC
authentication timers.
mac-authentication timer { offline-detect
offline-detect-value | quiet quiet-value |
server-timeout server-timeout-value }
By default, the offline detect
timer is 300 seconds, the quiet
timer is 60 seconds, and the
server timeout timer is 100
seconds.
