of the VLAN. Egress Member Ports are ports that will be
transmitting traffic for the VLAN. These ports can be either
tagged or untagged.
F 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.
- Non-Member - specifies the port as not being a member of
the VLAN, but the port can become a member of the VLAN
dynamically.
Tagging (U/T): Allows an individual port to be specified as either Tagging or
Untagging.
U 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.
T 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.
To create an 802.1Q VLAN, toggle the Action field to Add/Modify using the space bar. Enter a VLAN ID
number in the VID# field and a name for the new VLAN in the VLAN Name field.
Choose which ports will be members of the new VLAN and enter their membership status in the
Membership (E/F/-) field. The status indicators of the individual ports can be entered directly from the
keyboard or toggled using the space bar. Moving between the status indicators of the individual ports is
accomplished using the arrow keys.
To set the 802.1Q VLAN membership status of a port:
To enter the 802.1Q VLAN status for a port, highlight the first field of Membership (E/F/-). Each port’s
802.1Q VLAN membership can be set individually by highlighting the port’s entry using the arrow keys,
and then toggling between E, F, or – using the space bar.
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:
Highlight the first field of Tagging (U/T) field. Each port’s state can be set by highlighting the port’s
entry using the arrow keys and then toggling between U or T using the space bar.
If the port is attached to a device that is not IEEE 802.1Q VLAN compliant (VLAN-tag unaware), then
the port should be set to U – Untagged.
If the port is attached to a device that is IEEE 802.1Q VLAN compliant, (VLAN-tag aware), then the port
should be set to T – Tagged.
