 Port Config 
Port Select:  Click the Select button to quick-select the corresponding entry based 
on the port number you entered. 
Select:  Select the desired port for configuration. It is multi-optional. 
Port:  Displays the port number. 
Status:  Enable/Disable the GVRP feature for the port. The port type should 
be set to TRUNK before enabling the GVRP feature. 
Registration 
Mode: 
Select the Registration Mode for the port. 
 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.  
 Forbidden: In this mode, a port cannot register/deregister 
VLANs. It only propagates VLAN 1 information. 
LeaveAll Timer:  Once the LeaveAll Timer is set, the port with GVRP enabled can send 
a LeaveAll message after the timer times out, so that other GARP 
ports can re-register all the attribute information. After that, the 
LeaveAll timer will start to begin a new cycle. The LeaveAll Timer 
ranges from 1000 to 30000 centiseconds. 
Join Timer:  To guarantee the transmission of the Join messages, a GARP port 
sends each Join message two times. The Join Timer is used to define 
the interval between the two sending operations of each Join 
message. The Join Timer ranges from 20 to 1000 centiseconds. 
Leave Timer:  Once the Leave Timer is set, the GARP port receiving a Leave 
message will start its Leave timer, and deregister the attribute 
information if it does not receive a Join message again before the 
timer times out. The Leave Timer ranges from 60 to 3000 
centiseconds. 
LAG:  Displays the LAG to which the port belongs. 
Note: 
LeaveAll Timer >= 10* Leave Timer, Leave Timer >= 2*Join Timer
