If port type is
Unaware
, all frames are classified to the port VLAN ID and
tags are not removed.
Ingress
Filtering
Enable ingress filtering on a port by checking the box. This parameter
affects VLAN ingress processing. If ingress filtering is enabled and the
ingress port is not a member of the classified VLAN of the frame, the
frame will be discarded. By default, ingress filtering is disabled (no check
mark).
Frame Type
Determines whether the port accepts all frames or only tagged/untagged
frames. This parameter affects VLAN ingress processing. If the port only
accepts tagged frames, untagged frames received on the port will be
discarded. By default, the field is set to
All
.
Port VLAN
Mode
The allowed values are
None
or
Specific
. This parameter affects VLAN
ingress and egress processing.
If
None
is selected, a VLAN tag with the classified VLAN ID is inserted in
frames transmitted on the port. This mode is normally used for ports
connected to VLAN-aware switches. Tx tag should be set to Untag_pvid
when this mode is used.
If
Specific
(the default value) is selected, a port VLAN ID can be
configured (see below). Untagged frames received on the port are
classified to the port VLAN ID. If VLAN awareness is disabled, 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 will be inserted in the frame.
Port VLAN ID
Configures the VLAN identifier for the port. The allowed range of the
values is 1 through 4095. The default value is 1. The port must be a
member of the same VLAN as the port VLAN ID.
Tx Tag
Determines egress tagging of a port.
Untag_pvid
: all VLANs except the
configured PVID will be tagged.
Tag_all
: all VLANs are tagged.
Untag_all
: all VLANs are untagged.
