Phase 2
In Phase 1, you gave the new VLAN a name and specified the ports that
will be members of the VLAN. It is important to know, however, that the
untagged ports of the new VLAN are not automatically removed from
their current VLAN assignment. Instead, you must manually remove
them yourself. This involves reconfiguring the existing VLANs by
removing untagged ports that are members of the new VLAN.
Remember, an untagged port can be a member of only one VLAN at a
time. Unless you reconfigure the VLANs, an untagged port can end up
being a member of more than one VLAN and this could result in
unpredictable performance by your VLANs.
To reconfigure your existing VLANS, do the following:
1. From the Omega Main Menu, select Virtual LANs/QoS. The Virtual
LAN/QoS menu in Figure 44 is displayed.
2. Select Virtual LAN definitions.
3. Select an existing VLAN that contains an untagged port that you have
assigned to the new VLAN you created in Phase 1.
The VLAN Configuration window for the selected VLAN is displayed.
An example is shown in Figure 47. The window displays the name of
the VLAN and the tagged and untagged ports of the VLAN. The
example is for the Default VLAN.

4. Modify the All Ports on VLAN field so that it no longer includes the
untagged ports that you have assigned to the new VLAN. Press
.
5. Return to the Omega Main Menu.
6. Repeat this procedure to modify any other VLANs that contain
untagged ports that you have assigned to the new VLAN.
