802.1Q VLAN Configuration
Enabling/Disabling GVRP (GARP VLAN Registration Protocol)
6-26 Matrix E1 Series (1G694-13) Configuration Guide
Figure 6-1 Example of VLAN Propagation via GVRP
Configuring a VLAN on an 802.1Q switch creates a static GVRP entry. The entry will always
remain registered and will not time out. However, dynamic entries will time-out and their
registrations are removed from the member list if the end station A is removed. This ensures that if
switches are disconnected, or if end stations are removed, the registered information remains
accurate.
The end result is that the Port Egress List of a port is updated with information about VLANs that
reside off that port, even if the actual station on the VLAN is several hops away.
