•
Include - This port is always a member of this VLAN. This is equivalent to registration fixed in the
IEEE 802.1Q standard.
•
Exclude - This port is never a member of this VLAN. This is equivalent to registration forbidden
in the IEEE 802.1Q standard.
•
Autodetect - To allow the port to be dynamically registered in this VLAN via GVRP. The port will
not participate in this VLAN unless a join request is received on this port. This is equivalent to
registration normal in the IEEE 802.1Q standard.
Configured The configured degree of participation of this port in this VLAN. The permissible values are:
