- Access—The interface is an untagged member of a single VLAN. A port
configured in this mode is known as an access port.
- 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 device is in Q-in-Q mode when it has one or more
customer ports. See QinQ.
- Private VLAN - Host—Select to set the interface as either isolated or
community. Then select either an isolated or community VLAN in the
Secondary VLAN - Host field.
- Private VLAN - Promiscuous—Select to set the interface as promiscuous.
• 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.
• Primary VLAN—Select the primary VLAN in the private VLAN. The primary
VLAN is used to allow Layer 2 connectivity from promiscuous ports to
isolated ports and to community ports.
• Secondary VLAN - Host—Select an isolated or community VLAN for those
hosts that only require a single secondary VLAN.
