6.3.3 Notes
•
On Import VLAN, VLAN Manager will automatically trim leading/embedded/trailing
spaces from VLAN Names.
•
If a port on a Non-Existing device is associated with a port channel, its tool tip text
on the Device Panel will continue to show its interface name instead of its port
channel number.
•
Attempting to perform any VLAN operation after modifying the uplink port of the
device to 'Access-Untagged' or 'Trunk-Untagged' will result to an error message
"Unable to communicate. Confirm valid SNMP settings or login, and if the network
is functional" even if the device uplink port has been changed. Establish new
connection with the device before performing any VLAN operation.
•
The Default VLAN cannot be imported into or exported from VLAN Manager.
•
VLAN Names that contain any of the invalid special characters may cause VLAN
Manager to hang. To avoid this, do not use any of the invalid special characters when
defining VLAN Names through the CLI.
•
VLAN name with prohibited character set in CLI will be displayed in Modify window
except when the VLAN name or the last character of the VLAN name is a hash sign
'#'. Attempting to modify a vlan name containing a hash sign # will result to an error
message.
•
Ports or port channels that are General Untagged members of more than one
VLAN cannot be associated as Trunk members of another VLAN. Attempting
to do so will result to an error message depending on what the device will throw
as an error message.
•
Ports or port channels that are Trunk or General members of more than one VLAN
cannot be associated as Access members of another VLAN. Attempting to do so will
result to an error message depending on what the device will throw as an error
message.
•
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 will result in the error message: "Cannot associate
tagged port or port channel to the 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-8000GS, especially if the device is in stack mode.
•
In stacked mode, VM will display the maximum number of devices supported in
stack regardless of the actual device setup and will display a generic device image
with maximum of 48 ports. A "Non-existing" label will be displayed on the device
not present in the stack.
