Protocol-Based Vlan Configuration; Introduction To Protocol-Based Vlan - 3Com 4500G Family Configuration Manual

MAC-based VLANs are available only on hybrid ports.
Because MAC-based dynamic port assignment is mainly configured on the downlink ports of the
user access devices, do not enable this function together with link aggregation.
With MSTP enabled, if the MST instance for the corresponding VLAN is blocked, the packet with
the unknown source MAC address will fail to be sent to the CPU. As a result, the receiving port
cannot be dynamically assigned to the corresponding VLAN. Since MAC-based dynamic port
assignment is mainly configured on the access side, you are recommended not to configure it
together with MSTP.
Follow these steps to configure a MAC-based VLAN:

Required
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.

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

Disabled by default
Optional
By default, VLANs are
preferentially matched based
on MAC addresses.
