8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.

Usage Information

Fixed registration prevents an interface, configured using the command line, to

belong to a VLAN (static configuration) from being unconfigured when it receives a

Leave message. Therefore, Registration mode on that interface is fixed.

Normal registration is the default registration. The port’s membership in the VLAN

depends on GVRP. The interface becomes a member of a VLAN after learning

about the VLAN through GVRP. If the VLAN is removed from the port that sends

GVRP advertisements to this device, the port stops being a member of the VLAN.

To advertise or learn about VLANs through GVRP, use the forbidden command

when you do not want the interface.
