Figure 7-20. 802.1Q Static VLANs Entry Settings – Edit window
The following fields can then be set:
Parameter Description
VLAN ID (VID)
Allows the entry of the name of an existing VLAN. VLANs
can be identified by either the VID or the VLAN name.
Port
Allows an individual port to be specified as member of a
VLAN.
Tag
Allows an individual port to be specified as either Tagging or
Untagging. No Check in the Tag field, untagging, specifies
the port as an Untagging member of the VLAN. When an
untagged packet is transmitted by the port, the packet
header remains unchanged. When a tagged packet exits the
port, the tag is stripped and the packet is changed to an
untagged packet. A Check in the Tag field, tagging, specifies
the port as a Tagging member of the VLAN. When an
untagged packet is transmitted by the port, the packet
header is changed to include the 32-bit tag associated with
the PVID (Port VLAN Identifier – see below). When a tagged
packet exits the port, the packet header is unchanged.
Egress
Egress Member - specifies the port as being a static member
of the VLAN. Egress Member Ports are ports that will be
transmitting traffic for the VLAN. These ports can be either
tagged or untagged.
Forbidden
Forbidden Non-Member - specifies the port as not being a
member of the VLAN and that the port is forbidden from
becoming a member of the VLAN dynamically.
Choose which ports will be members of the new VLAN and enter their membership status in the Port
field. Next, determine which of the ports that are members of the new VLAN will be Tagged or Untagged
ports.
To set a port as either a Tagged or an Untagged port:
Check the Tag click-box for each port that will be a tagging port. Each port’s state can be set by
clicking the port’s click-box.
