•
Interface VLAN Mode—Select the interface mode for the VLAN. The options are:
-
General—The interface can support all functions as defined in the IEEE 802.1q
specification. The interface can be a tagged or untagged member of one or more
VLANs.
-
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.
•
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. If None is selected if the interface is not in private VLAN mode.
•
Secondary VLAN - Host—Select an isolated or community VLAN for those hosts that
only require a single secondary VLAN.
