Chapter 24: Port-based and Tagged VLANs
472 Section VI: Virtual LANs
contain spaces or special characters, such as asterisks (*) or
exclamation points (!).
If the VLAN will be unique in your network, then the name should be
unique as well. If the VLAN will be part of a larger VLAN that spans
multiple switches, then the name for the VLAN should be the same on
each switch where nodes of the VLAN are connected.
Note
A VLAN must be assigned a name.
6. Type 2 to select VLAN ID (VID.
The following prompt is displayed:
Enter new value -> [2 to 4094] ->
7. Type a VID value for the new VLAN. The range for the VID value is 1
to 4094.
The AT-S63 Management Software uses the next available VID
number on the switch as the default value. If this VLAN is unique in
your network, then its VID should also be unique. If this VLAN is 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 spans three switches, you should
assign the Sales VLAN on each switch the same VID value.
Note
A VLAN must have a VID.
It is important to note that 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-9400 Switch to a
network that already contains VLANs that use VIDs 2 through 24, the
AT-S63 Management Software still uses 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.
8. Type 3 to toggle VLAN Type so that it displays Port Based, the default
setting. This is the correct setting when creating a port-based or
tagged VLAN.
