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.
( 802.1Q mode only)
PVID Allow assign PVID for 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 as same as the VLAN ID that the port belong to VLAN group, or the
untagged traffic will be dropped.
Acceptable Frame
Type Specifies the types of frames that may be received on this port. The options are
'All' and 'Tagged only'.
• All- untagged frames or priority tagged frames received on this port are
accepted and assigned the value of the Port VLAN ID for this port.
• Tagged only - untagged frames or priority tagged frames received on this port
are discarded.
With either option, VLAN tagged frames are forwarded in accordance to the
802.1Q VLAN specification.
( 802.1Q mode only)
Ingress Filtering Enabled - the frame is discarded if this port is not a member of the VLAN with
which this frame is associated. In a tagged frame, the VLAN is identified by the
VLAN ID in the tag. In an untagged frame, the VLAN is the Port VLAN ID specified
for the port that received this frame.
Disabled - all frames are forwarded in accordance with the 802.1Q VLAN bridge
specification. The factory default is disabled.
( 802.1Q mode only)
Once [Accept Frame Type] be set to "Tagged only" and be applied, the management connection to
the switch might be lost. Please make sure your client's NIC or link partner provided with VLAN
Tagged capability or through other tagged link path.

Tagging and Untagging
Every port on an 802.1Q compliant switch can be configured as tagging or untagging.
。 Tagging: Ports with tagging enabled will put the VID number, priority and other VLAN information into the header of
all packets that flow into those ports. If a packet has previously been tagged, the port will not alter the packet, thus
keeping the VLAN information intact. The VLAN information in the tag can then be used by other 802.1Q compliant
devices on the network to make packet-forwarding decisions.
。 Untagging: Ports with untagging enabled will strip the 802.1Q tag from all packets that flow into those ports. If the
packet doesn't have an 802.1Q VLAN tag, the port will not alter the packet. Thus, all packets received by and
