GVRP Settings

Users can determine whether the Switch will share its VLAN configuration information with other GARP VLAN Registration
Protocol (GVRP) enabled switches. In addition, Ingress Checking can be used to limit traffic by filtering incoming packets whose
PVID does not match the PVID of the port. Results can be seen in the table under the configuration settings.
To view the following window, click L2 Features > VLAN > GVRP Settings:

Description
Click the radio buttons to enable or disable GVRP settings.
Use the drop-down menus to select a range of ports that will be included in the Port-based
VLAN.
This field is used to manually assign a PVID to a VLAN. The Switch's default is to assign all
ports to the default VLAN with a VID of 1.The PVID is used by the port to tag outgoing,
untagged packets, and to make filtering decisions about incoming packets. If the port is
specified to accept only tagged frames - as tagging, and an untagged packet is forwarded to
the port for transmission, the port will add an 802.1Q tag using the PVID to write the VID in
the tag. When the packet arrives at its destination, the receiving device will use the PVID to
make VLAN forwarding decisions. If the port receives a packet, and Ingress filtering is
Enabled, the port will compare the VID of the incoming packet to its PVID. If the two are
unequal, the port will drop the packet. If the two are equal, the port will receive the packet.
The GARP VLAN Registration Protocol (GVRP) enables the port to dynamically become a
member of a VLAN. GVRP is Disabled by default.
