The lower limit of Hold timer is 10 centiseconds. You can change its upper limit 
by changing the value of Join timer.
You can change the lower limit and upper limit of Join timer by changing the 
value of Hold timer and Leave timer respectively.
You can change the lower limit and upper limit of Leave timer by changing the 
value of Join timer and LeaveAll timer respectively.
The upper limit of LeaveAll timer is 32765 centiseconds. You can change its 
lower limit by changing the value of Leave timer.

Configuring GVRP
GVRP Overview
GARP VLAN Registration Protocol (GVRP) is a GARP application. Based on GARP 
operating mechanism, GVRP provides maintenance of the dynamic VLAN 
registration information in the switch and propagates the information to other 
switches. All the GVRP-supporting switches can receive VLAN registration 
information from other switches and dynamically update the local VLAN 
registration information including the active members and through which port 
those members can be reached. All the GVRP-supporting switches can propagate 
their local VLAN registration information to other switches so that the VLAN 
information can be consistent on all GVRP-supporting devices in one switching 
network. The VLAN registration information propagated by GVRP includes both 
the local static registration information configured manually and the dynamic 
registration information from other switches.
GVRP is described in details in the IEEE 802.1Q standard. 3Com series switches 
fully support the GARP compliant with the IEEE standards.
Main GVRP configuration includes:
