MAC-based VLANs are available only on hybrid ports.
z
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.
z
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:
