Allied Telesis AlliedView-EMS 4.0.1 VLAN MANAGER - Manual (Page 40)

• The current firmware version allows you to pre-configure switches that may be
added to the stack in the future. Pre-configured switches are identified by a "Non-
Existing" label that appears above the device panel in the Add VLAN and Modify
VLAN dialog boxes. Ports on pre-configured switches can be included in a VLAN
provided they are not members of a port channel. Any attempt to associate a pre-
configured switch port that is a member of a port channel to a VLAN will result in
the error message: "Port is a ghost port that belongs to a Port-Channel."
