Configuring GVRP
The GARP VLAN Registration Protocol (GVRP) protocol 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 to
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—Displays the number of GVRP VLANs allowed to participate in GVRP operation.
l
Maximum number of GVRP VLANs after Reset—Sets another value for GVRP VLANs and is used for tuning. This value becomes valid after reset only.
l
The maximum number of GVRP VLANs includes all the VLANs participating in GVRP operation regardless whether 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 128 because of the memory restrictions.
l
The maximum number of VLANs (managed through Max VLANs MIB variable) limits the maximum number of GVRP VLANs.
l
To ensure the correct operation of the GVRP protocol, users are advised to 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.
l
The number of all dynamic VLANs participating in GVRP both currently configured (initial number of dynamic GVRP VLANs is 128) and expected to be
l
configured.
Increasing the value of maximum number of the GVRP VLANs to a value beyond the sums, allows users to run GVRP, and not reset the device to receive a
larger amount of GVRP VLANs. For example, if three VLANs exist and another two VLANs are expected to be configured as a result of VLAN static or dynamic
registration, set the maximum number of GVRP VLANs after reset to 10. To open the GVRP Parameters page:
Click Switch > VLAN > GVRP Parameters in the Tree View. The GVRP Parameters page opens.
