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 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 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.
Using MAC authentication with other features
VLAN assignment
You can specify a VLAN in the user account for a MAC authentication user to control its access to
network resources. After the user passes MAC authentication, the authentication server, either the local
access device or a RADIUS server, assigns the VLAN to the port as the default VLAN. After the user logs
off, the initial default VLAN, or the default VLAN configured before any VLAN is assigned by the
authentication server, restores. If the authentication server assigns no VLAN, the initial default VLAN
applies.
NOTE:
•
A hybrid port is always assigned to a server-assigned VLAN as an untagged member. After the
assignment, do not re-configure the port as a tagged member in the VLAN.
• If MAC-based VLAN is enabled on a hybrid port, the device maps the server-assigned VLAN to the
MAC address of the user. The default VLAN of the hybrid port does not change.
ACL assignment
You can specify an ACL in the user account for a MAC authentication user to control its access to network
resources. After the user passes MAC authentication, the authentication server, either the local access
device or a RADIUS server, assigns the ACL to the access port to filter the traffic from this user. You must
configure the ACL on the access device for the ACL assignment function. You can change ACL rules while
the user is online.
Guest VLAN
You can configure a guest VLAN to accommodate MAC authentication users that have failed MAC
authentication on the port. Users in the MAC authentication guest VLAN can access a limited set of
network resources, such as a software server, to download anti-virus software and system patches. If no
