VLAN Configuration Command Set
Enabling/Disabling GVRP (GARP VLAN Registration Protocol)
Matrix E1 Series (1G58x-09 and 1H582-xx) Configuration Guide 7-43
Figure 7-1 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 will be 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.
Commands
The commands used to configure GVRP are listed below and described in the associated section as
shown.
