Configuring GVRP

GARP VLAN Registration Protocol (GVRP) is specifically provided for automatic distribution of
VLAN membership information among VLAN-aware bridges. GVRP allows VLAN-aware bridges to
automatically learn VLANs to bridge ports mapping, without having to individually configure each
bridge and register VLAN membership.
To minimize the memory requirements when running the GVRP protocol, two proprietary tuning
variables have been added to the standard variables:
•
Maximum number of GVRP VLANs
— Number of GVRP VLANs allowed to participate in
GVRP operation.
•
Maximum number of GVRP VLANs after Reset
— Maximum number of GVRP VLANs
after Reset is used for tuning. This value becomes valid after reset only.
The maximum number of GVRP VLANs includes all the VLANs participating in GVRP operation
regardless if they are static or dynamic.
The following should be considered when specifying the maximum number of VLANs
participating in GVRP by setting the Maximum number of GVRP VLANs after Reset value:
• The default maximum number of GVRP VLANs is equal to 255.
• The maximum number of VLANs (managed through Max VLANs MIB variable) limits the
maximum number of GVRP VLANs.
To ensure the correct operation of the GVRP protocol, set the maximum number of GVRP VLANs
equal to a value which significantly exceeds the sum of:
• The number of all static VLANs both currently configured and expected to be configured.
• The number of all dynamic VLANs participating in GVRP both currently configured (initial
number of dynamic GVRP VLANs is 255) and expected to be configured.
The

interface basis. To open the
