Ports or port channels that are General members of a VLAN and whose PVID is not

set to the default configuration (PVID=1) cannot be associated as Access/Trunk

members of another VLAN. Attempting to do so will result in the error message:

"Port / Channel is untagged in a VLAN which differs from

PVID."

During an Add/Modify VLAN operation, VLAN Manager processes and configures

ports and port channels sequentially. When an error is encountered, succeeding
ports and port channels are no longer processed. In a Modify VLAN operation, the

port or port channel on which the error occurred will be returned to its original

state.

Any attempt to modify the VLAN membership mode of a port or port channel that

is an Access/Trunk/General Untagged member of the Default VLAN to a

Trunk/General Tagged member or a Forbidden member will result in the error

message: "Forbidden or Tagged Member not allowed in Default VLAN."

After initiating a Restart operation, VLAN Manager will continuously attempt to

connect to the device for up to 1 minute until a connection is established. If a

minute has elapsed and connection has still not been established, an error message

will be displayed.

It may take a while for VLAN Manager to retrieve or save VLAN information

from/to the AT-8000S, especially if the device is in stack mode.

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 belongs to a Port-Channel."
