including VL
AN members, ports through which the VLAN members can be reached, and so on. 
The switch also propagates the local VLAN registration information to other switches so that all the 
switching devices in the same switched network can have the same VLAN information. The VLAN 
registration information includes not only the static registration information configured locally, but 
also the dynamic registration information, which is received from other switches. 
In this switch, only the port with TRUNK link type can be set as the GVRP application entity to 
maintain the VLAN registration information. GVRP has the following three port registration modes: 
Normal, Fixed, and Forbidden. 
  Normal: In this mode, a port can dynamically register/deregister a VLAN and propagate the 
dynamic/static VLAN information. 
  Fixed: In this mode, a port cannot register/deregister a VLAN dynamically. It only propagates 
static VLAN information. That is, the port in Fixed mode only permits the packets of its static 
VLAN to pass. 
  Forbidden: In this mode, a port cannot register/deregister VLANs. It only propagates VLAN 1 
information. That is, the port in Forbidden mode only permits the packets of the default VLAN 
(namely VLAN 1) to pass.
