Configures how a port processes the VLAN ID in ingress frames. (Default:
Unaware)
C-port - For customer ports, each frame is assigned to the VLAN indicated in the
VLAN tag, and the tag is removed.
S-port - For service ports, the EtherType of all received frames is changed to
0x88a8 to indicate that double-tagged frames are being forwarded across the
switch. The switch will pass these frames on to the VLAN indicated in the outer
tag. It will not strip the outer tag, nor change any components of the tag other
than the EtherType field.
S-custom-port - For custom service ports, the EtherType of all received frames
is changed to value set in the Ethertype for Custom S-ports field to indicate that
double-tagged frames are being forwarded across the switch. The switch will
pass these frames on to the VLAN indicated in the outer tag. It will not strip the
outer tag, nor change any components of the tag other than the EtherType field.
Unaware - All frames are classified to the Port VLAN ID and tags are not
removed.
Determines how to process frames tagged for VLANs for which the ingress port is
not a member. (Default: Disabled)
Ingress filtering only affects tagged frames.
If ingress filtering is enabled and a port receives frames tagged for VLANs for
which it is not a member, these frames will be discarded.
If ingress filtering is disabled and a port receives frames tagged for VLANs for
which it is not a member, these frames will be flooded to all other ports.
Ingress filtering does not affect VLAN independent BPDU frames, such as
GVRP or STP. However, they do affect VLAN dependent BPDU frames, such as
GMRP.
Sets the interface to accept all frame types, including tagged or untagged frames,
only tagged frames, or only untagged frames. When set to receive all frame types,
any received frames that are untagged are assigned to the default VLAN. When
set to receive only tagged frames, all untagged frames received on the interface
are discarded. (Option: All, Tagged, Untagged; Default: All)
Determines how to process VLAN tags for ingress and egress traffic. (Options:
None, Specific; Default: Specific)
None - The ID for the VLAN to which this frame has been assigned is inserted in
frames transmitted from the port. The assigned VLAN ID can be based on the
ingress tag for tagged frames, or the default PVID for untagged ingress frames.
Note that this mode is normally used for ports connected to VLAN-aware
switches.
Specific - A Port VLAN ID can be configured (as described below). Untagged
frames received on the port are classified to the Port VLAN ID. If Port Type is
Unaware, all frames received on the port are classified to the Port VLAN ID. If
the classified VLAN ID of a frame transmitted on the port is different from the
Port VLAN ID, a VLAN tag with the classified VLAN ID is inserted in the frame.
When forwarding a frame from this switch along a path that contains any VLAN-
aware devices, the switch should include VLAN tags. When forwarding a frame
from this switch along a path that does not contain any VLAN-aware devices
(including the destination host), the switch should first strip off the VLAN tag
before forwarding the frame.
VLAN ID assigned to untagged frames received on the interface. (Range: 1-4095;
Default: 1) The port must be a member of the same VLAN as the Port VLAN ID.
