Defining VLAN Interface Settings
The VLAN Interface Page contains fields for managing ports that are part of a VLAN.
To define a VLAN interface:

Figure 76: VLAN Interface Page
The VLAN Interface Page displays the VLAN interface information for a selected Port/Unit or Trunk:
• Select the interfaces displayed in the table.
– Ports of Unit — Specifies the port and stacking member for which the VLAN mapping is displayed.
– Trunk — Specifies the trunk for which the VLAN mapping is displayed.
• Interface — Displays the port or trunk number.
• Interface VLAN Mode — Indicates the port (or trunk) mode in the VLAN. The possible values are:
– General — Indicates the port belongs to VLANs, and each VLAN’s interface is user-defined as tagged or
untagged (full IEEE802.1q mode).
– Access — Indicates a port belongs to a single untagged VLAN. When a port is in Access mode, the
packet types which are accepted on the port cannot be designated. Ingress filtering is always enabled for
ports in Access mode.
– Trunk — Indicates the port belongs to VLANs in which all VLANs are tagged, except for one VLAN that is
untagged.
• PVID — Port Default VLAN ID. Assigns a VLAN ID to untagged packets. The possible values are 1-4094.
VLAN 4095 is defined as per standard and industry practice as the Discard VLAN. Packets classified to the
Discard VLAN are dropped.
