• 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.
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.
• 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, 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.
• The number of all dynamic VLANs participating in GVRP both currently configured
(initial number of dynamic GVRP VLANs is 128) and expected to be 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.
