Configuring VLAN Behavior for Interfaces

You can configure VLAN behavior for specific interfaces, including the default VLAN identifier (PVID), accepted frame types, ingress filtering, GVRP status, and GARP timers.

Command Usage

•GVRP – GARP VLAN Registration Protocol defines a way for switches to exchange VLAN information in order to automatically register VLAN members on interfaces across the network.

•GARP – Group Address Registration Protocol is used by GVRP to register or deregister client attributes for client services within a bridged LAN. The default values for the GARP timers are independent of the media access method or data rate. These values should not be changed unless you are experiencing difficulties with GVRP registration/deregistration.

Command Attributes

•PVID – VLAN ID assigned to untagged frames received on the interface. (Default: 1)

-If an interface is not a member of VLAN 1 and you assign its PVID to this VLAN, the interface will automatically be added to VLAN 1 as an untagged member. For all other VLANs, the PVID must be defined first, then the status of the VLAN can be configured as a tagged or untagged member.

•Acceptable Frame Type – Sets the interface to accept all frame types, including tagged or untagged frames, or only tagged frames. When set to receive all frame types, any received frames that are untagged are assigned to the default VLAN. (Options: All, Tagged; Default: All)

•Ingress Filtering – Determines how to process frames tagged for VLANs for which the ingress port is not a member. Ingress Filtering is always enabled.

(Default: Enabled)

-Ingress filtering only affects tagged frames.

-If a port receives frames tagged for VLANs for which it is not a member, these frames will be discarded.

-Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP or STP. However, they do affect VLAN dependent BPDU frames, such as GMRP.

•Mode – Indicates VLAN membership mode for an interface. (Default: Hybrid)

-1Q Trunk – Specifies a port as an end-point for a VLAN trunk. A trunk is a direct link between two switches, so the port transmits tagged frames that identify the source VLAN. Note that frames belonging to the port’s default VLAN (i.e., associated with the PVID) are also transmitted as tagged frames.

-Hybrid – Specifies a hybrid VLAN interface. The port may transmit tagged or untagged frames.

•Trunk Member – Indicates if a port is a member of a trunk. To add a trunk to the selected VLAN, use the last table on the VLAN Static Table page.
