802.1Q Port Settings D-Link DES-3326S Layer 3 Switch The Port VLAN ID (PVID) menu, shown below, allows you to 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. Figure 19- 4. Port VLAN ID (PVID) The following fields can then be set: Parameter Description Unit Choose the Switch that the VLAN will be created on. PVID A Port VLAN Identifier is a classification mechanism that associates a port with a specific VLAN and is used to make forwarding decisions for untagged packets received by the port. For example, if port #2 is assigned a PVID of 3, then all untagged packets received on port #2 will be assigned to VLAN 3. This number is generally the same as the VID# number assigned to the port in the Edit 802.1Q VLANs menu above. GVRP The Group VLAN Registration Protocol (GVRP) enables the port to dynamically become a member of a VLAN. Ingress Checking This field can be toggled using the space bar between Enabled and Disabled. Enabled enables the port to compare the VID tag of an incoming packet with the PVID number assigned to the port. If the two are different, the port filters (drops) the packet. Disabled disables Ingress filtering. 140
