VLAN Management Defining VLAN Membership 12 - Trunk-The interface is an untagged member of one VLAN at most, and is a tagged member of zero or more VLANs. A port configured in this mode is known as a trunk port. - Customer-Selecting this option places the interface in QinQ mode. This enables you to use your own VLAN arrangements (PVID) across the provider network. The switch is in Q-in-Q mode when it has one or more customer ports. See QinQ. • Administrative PVID-Enter the Port VLAN ID (PVID) of the VLAN to which incoming untagged and priority tagged frames are classified. The possible values are 1 to 4094. • Frame Type-Select the type of frame that the interface can receive. Frames that are not of the configured frame type are discarded at ingress. These frame types are only available in General mode. Possible values are: - Admit All-The interface accepts all types of frames: untagged frames, tagged frames, and priority tagged frames. - Admit Tagged Only-The interface accepts only tagged frames. - Admit Untagged Only-The interface accepts only untagged and priority frames. • Ingress Filtering-(Available only in General mode) Select to enable ingress filtering. When an interface is ingress filtering enabled, the interface discards all incoming frames that are classified as VLANs of which the interface is not a member. Ingress filtering can be disabled or enabled on general ports. It is always enabled on access ports and trunk ports. STEP 5 Click Apply. The parameters are written to the Running Configuration file. Defining VLAN Membership The Port to VLAN and Port VLAN Membership pages display the VLAN memberships of the ports in various presentations. You can use them to add or remove memberships to or from the VLANs. When a port is forbidden default VLAN membership, that port is not allowed membership in any other VLAN. An internal VID of 4095 is assigned to the port. Cisco Small Business 200 Series Smart Switch Administration Guide 162
