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."
•
VLAN Manager may intermittently fail and may return an error "Confirm valid IP
Address, SNMP settings or login, and if the network is functional." when AT-8000S
devices are in stacked mode. To prevent this, go to File -> Properties and increase
the Retry Timeout value.
