Ethertype for
custom
S-Ports
This field specifies the Ether type used for custom S-ports. This is a global setting
for all custom S-ports.
Port
The switch port number to which the following settings will be applied.
Port type
Port can be one of the following types:
Unaware
,
Custom
(
C-port
),
Service
(
S-port
),
Custom Service
(
S-custom-port
).
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 P V I D w i l l b e t a g g e d .
Tag_all
: all V L A N ’ s are tagged.
Untag_all
: all VLANs are untagged.
