C H A P T E R 5 Virtual LANs (VLANs)
105
MAC-Based VLANs
MAC-Based VLANs allow physical ports to be mapped to a VLAN
based on the source MAC address learned in the forwarding
database (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.
