Configuring A Mac Address-Based Vlan - 3Com 4510G Configuration Manual

The device associates MAC addresses with VLANs dynamically based on the information provided by
the authentication server. If a user goes offline, the corresponding MAC address-to-VLAN association
is removed automatically. Automatic configuration requires MAC address-to–VLAN mapping be
configured on the authentication server. For detailed information, refer to 802.1X Configuration in the
Security Volume.
The two configuration approaches can be used at the same time, that is, you can configure a MAC
address-to-VLAN entry on both the local device and the authentication server at the same time. Note
that the MAC address-to-VLAN entry configuration takes effect only when the configuration on the
local device is consistent with that on the authentication server. Otherwise, the previous configuration
takes effect.

Configuring a MAC Address-Based VLAN

MAC-based VLANs are available only on hybrid ports.

Use either command.
In Ethernet interface view, the
subsequent configurations
apply only to the current port;
in port group view, the
subsequent configurations
apply to all ports in the port
group.

By default, a hybrid port only
permits the packets of VLAN 1
to pass through.
