Defining VLAN Interface Settings

You can configure VLAN behavior for specific interfaces, including the default VLAN
identifier (PVID), accepted frame types, ingress filtering, GVRP status, and GARP.
The Interface Configuration Page contains parameters for defining VLAN behavior
for specific interfaces.
Note:
After reboot the "old" system default VLAN and its associated config is removed
from the system config.
Command Attributes
• Unit No. — Indicates the stacking member for which the interface configuration
information is displayed.
• Interface — Displays the port number included in the VLAN.
• Interface VLAN Mode — Displays the port mode. The possible values are:
• General — Indicates the port belongs to VLANs, and each VLAN 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 cannot be enabled or disabled on an access port.
• Trunk — Indicates the port belongs to VLANs in which all ports are tagged,
except for one port that can be untagged.
• Customer — Indicates the port belongs to a customer VLAN in which all ports
are double tagged. For more information, see Configuring Customer VLANs.
• Multicast TV VLAN — Indicates if a Multicast TV VLAN is enabled on the device.
Multicast TV VLANs enable VLANs to receive Multicast TV transmissions from
ports that are not Access ports.
• PVID — 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.
• Frame Type — Specifies the packet type accepted on the port. The possible field
values are:
• Admit Tag Only — Only tagged packets are accepted on the port.
• Admit All — Both tagged and untagged packets are accepted on the port.
• Ingress Filtering— Indicates whether ingress filtering is enabled on the port. The
possible field values are:
• Enable — Enables ingress filtering on the device. Ingress filtering discards
packets that are defined to VLANs of which the specific port is not a member.
• Disable — Disables ingress filtering on the device.
• Reserved VLAN — Indicates the VLAN selected by the user to be the reserved
VLAN if not in use by the system.
