The page includes the following fields:
Object Description
Port This is the logical port number for this row.
PVID Allows to assign PVID to selected port. The range for the PVID is 1-
4094.
The PVID will be inserted into all untagged frames entering the
ingress port. The PVID must be the same as the VLAN ID in that the
port belongs to VLAN group, or the untagged traffic will be dropped.
Untag VID Allows user to set the port to remove default VID. This option could be
edited when the Link Type is selected as Tagged.
Ingress Filtering Enable ingress filtering for a port byselecting this check 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 is discarded. By default, ingress filtering is
disabled (no checkmark).
Accept Frame Type Determines whether the port accepts all frames or only tagged
frames. This parameter affects VLAN ingress processing. If the port
only accepts tagged frames, untagged frames received on the port
are discarded. By default, the field is set to All.
Link Type Allow 802.1Q Untagged or Tagged VLAN for selected port.
When adding a VLAN to selected port, it tells the switch whether to
keep or remove the tag from a frame on egress.
Untag: outgoing frames without VLAN-Tagged.
Tagged: outgoing frames with VLAN-Tagged.
Q-in-Q Mode Sets the industrial managed switch to QinQ mode, and allows the
QinQ tunnel port to be configured. The default is for the industrial
managed switch to function in Disable mode.
Disable: The port operates in its normal VLAN mode. (This is the
default.)
MAN Port: Configures IEEE 802.1Q tunneling (QinQ) for an uplink
port to another device within the service provider network.
Customer Port: Configures IEEE 802.1Q tunneling (QinQ) for a client
access port to segregate and preserve customer VLAN IDs for traffic
crossing the service provider network.
Set Out layer VLAN
tag ether type
The Tag Protocol Identifier (TPID) specifies the ether type of incoming
packets on a tunnel access port.
802.1Q Tag: 8100
vMAN Tag: 88A8
Default: 802.1Q Tag
Note: The port must be a member of the same VLAN as the Port VLAN ID.
