• VLANs created dynamically with GVRP exist only as long as a GVRP-enabled device is sending
updates. If the devices no longer send updates, or GVRP is disabled, or the system is rebooted, all
dynamic VLANs are removed.
• GVRP manages the active topology, not non-topological data such as VLAN protocols. If a local
bridge must classify and analyze packets by VLAN protocols, manually configure protocol-based
VLANs, and simply rely on GVRP for VLAN updates. But if the local bridge must know only how to
reach a given VLAN, then GVRP provides all necessary information.
• The VLAN topologies that GVRP learns are treated differently from VLANs that are statically
configured. The GVRP dynamic updates are not saved in NVRAM, while static updates are saved in
NVRAM. When GVRP is disabled, the system deletes all VLAN interfaces that were learned through
GVRP and leaves unchanged all VLANs that were manually configured.
