Dynamic MAC-Based VLANs

The MAC-based VLAN feature controls network access by authenticating a host source MAC

address, and mapping the incoming packet source MAC to a VLAN. Mapping is based on the MAC

address of the end station connected to the physical port. Users who relocate can remain on the

same VLAN as long as they connect to any switch in the same domain, on a port which is permitted

in the VLAN. The MAC-based VLAN feature may be enabled for two types of hosts: static and

MAC-based VLAN activity is determined by authentication through a RADIUS server. Incoming traffic

that originates from a specific MAC address is forwarded only if the source MAC address-to-VLAN

mapping is successfully authenticated. While multi-device port authentication is in progress, all

traffic from the new MAC address will be blocked or dropped until the authentication succeeds.

Traffic is dropped if the authentication fails.

Static and dynamic hosts

Static hosts are devices on the network that do not speak until spoken to. Static hosts may not

initiate a request for authentication on their own. Such static hosts can be managed through a link

up or link down notification.

Dynamic hosts are "chatty" devices that generate packets whenever they are in the link up state.

Dynamic hosts must be authenticated before they can switch or forward traffic.

The MAC-based VLAN feature operates in two stages:
