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.
E - (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.
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.
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.
U - specifies the port as an Untagged 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 - specifies the port as a Tagged 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.
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.
Press APPLY to make the additions/deletions effective for the current session. To make enter the IP Interfaces into Non-
volatile RAM, highlight Save Changes from the Main Menu and press Enter.
In the following example screen, the VLAN "Accounting" - VID# 2 – has been added. Ports 7 and 8 are Egress ports (static
members of "Accounting"). Ports 5 and 6 are Forbidden ports (non-members and are not allowed to join the VLAN
"Accounting" dynamically.
