MAC-Based VLANs allow physical ports to be mapped to a VLAN based on the source
MAC address learned in the FDB. This feature allows you to designate a set of ports
that have their VLAN membership dynamically determined by the MAC address of the
end station that plugs into the physical port. You may configure the source MAC
address-to-VLAN mapping either offline, or dynamically on the switch. For example,
you could use this application for a roaming user who wishes to connect to a network
from a conference room. In each room, the user plugs into one of the designated ports
on the switch and is mapped to the appropriate VLAN. Connectivity is maintained to
the network with all of the benefits of the configured VLAN in terms of QoS, routing,
and protocol support.
