Setting GVRP
The GARP VLAN Registration Protocol (GVRP) allows network devices to
share VLAN information. The main purpose of GVRP is to allow switches
to automatically discover some of the VLAN information that would
otherwise need to be manually configured in each switch. This is helpful in
networks where VLANs span more than one switch. Without GVRP, you
must manually configure your switches to ensure that the various parts of
a VLAN can communicate across the different switches. GVRP, which is
an application of the Generic Attribute Registration Protocol (GARP), does
this for you automatically.
The AT-S100 Management Software uses GVRP protocol data units
(PDUs) to share VLAN information among GVRP-active devices. The
PDUs contain the VID numbers of the VLANs on the switch. A PDU
contains the VIDs of all the VLANs on the switch, not just the VID of which
the transmitting port is a member.
When a switch receives a GVRP PDU on a port, it examines the PDU to
determine the VIDs of the VLANs on the device that sent it.
Enabling or Disabling GVRP
By default, the GVRP feature is disabled. The syntax of the command is:
set gvrp enable|disable
To enable the GVRP feature, enter the following commands:
switch# configure terminal
switch(config)# set gvrp enable
