Port GVRP Settings
GARP VLAN Registration Protocol (GVRP) is a Generic Attribute Registration Protocol (GARP) application
that provides 802.1Q-compliant VLAN pruning and dynamic VLAN creation on 802.1Q trunk ports.
With GVRP, the Switch can exchange VLAN configuration information with other GVRP switches, prune
unnecessary broadcast and unknown unicast traffic, and dynamically create and manage VLANs on
switches connected through 802.1Q trunk ports.
To enable a port to dynamically become a member of a VLAN, highlight Configure Port GVRP Settings
on the IEEE 802.1Q VLANs Configuration menu and press Enter:
Figure 6-28. Port GVRP Settings screen
This screen allows you to enable or disable GARP VLAN Registration Protocol (GVRP), where GARP is
the Generic Attribute Registration Protocol, on individual ports. Enter the range of ports to be
configured in the first two fields and then toggle the GVRP State to On. Press APPLY to let your changes
take effect.
GVRP updates dynamic VLAN registration entries and communicates the new VLAN information across
the network. This allows, among other things, for stations to physically move to other switch ports and
keep their same VLAN settings, without having to reconfigure VLAN settings on the Switch.
Configure IGMP Snooping
IGMP Snooping can be globally enabled or disabled from the IGMP Snooping Settings screen.
To configure IGMP Snooping, highlight Configure IGMP Snooping on the Configuration menu and
press Enter.
