5. Select the VID field and enter a VID value for the new VLAN. The
range of the VID value is 2 to 4096. The default is the next available
VID number on the switch.
If this VLAN will be unique in your network, then its VID should also be
unique. If this VLAN will be part of a larger VLAN that spans multiple
switches, than the VID value for the VLAN should be the same on
each switch. For example, if you are creating a VLAN called Sales that
will span three switches, you should assign the Sales VLAN on each
switch the same VID value.
Note
A VLAN must have a VID.
The switch is only aware of the VIDs of the VLANs that exist on the
device, and not those that might already be in use in the network. For
example, if you add a new AT-8500 Series switch to a network that
already contains VLANs that use VIDs 2 through 24, the AT-S62
software will still use VID 2 as the default value when you create the
first VLAN on the new switch, even though that VID number is already
being used by another VLAN on the network. To prevent inadvertently
using the same VID for two different VLANs, you should keep a list of
all your network VLANs and their VID values.
6. Select the Name field and enter a name for the new VLAN.
The name can be from one to fifteen alphanumeric characters in
length. The name should reflect the function of the nodes that will be a
part of the VLAN (for example, Sales or Accounting). The name cannot
