• A MAC address cannot be configured to associate with more than 1 VLAN. If this is
attempted, the MAC address is associated with the most recent VLAN entry in the
MAC-to-VLAN database.
• The feature is intended to support one client per physical port. Once a client MAC
address has successfully registered, the VLAN association remains until the port
connection is dropped or the FDB entry ages out.

XAMPLE
In this following example, three VLANs are created: engineering, marketing, and sales. A
single MAC address is associated with each VLAN. The MAC address 00:00:00:00:00:02
has a group number of “any” or “0” associated with it, allowing it to be plugged into
any port that is in MacVlanDiscover mode (ports 10-15 in this case). The MAC address
00:00:00:00:00:01 has a group number of 10 associated with it, and can only be assigned
to a VLAN if inserted into ports 16 or 17. The MAC address 00:00:00:00:00:03 has a
group number of 200 associated with it and can only be inserted into ports 18 through
20.
