An Ingress Filter enables the port to compare the VID tag of an incoming packet with the both the VIDs
and PVIDs of VLANs assigned to the port. If the VID tag of an incoming port is different from either the
VID or PVID assigned to the port, the port filters (drops) the packet.
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. 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 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:
