Secton V: Virtual LANs 349
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 Series
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.
Name
Specify 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 are part
of the VLAN (for example, Sales or Accounting). The name cannot
contain spaces or special characters, such as asterisks (*) or
exclamation points (!).
If the VLAN is unique in your network, then the name should be unique
as well. If the VLAN is 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.
Type
Select Port Based as the Type. This is the default setting. This is the
correct setting when creating a port-based or tagged VLAN.
Note
The Type selection of Protected is used to create a protected ports
VLAN, as explained in Chapter 23, “Protected Ports VLANs” on
page 377.
6. To select the ports for the VLAN, click on the appropriate ports in the
switch image. Clicking repeatedly on a port toggles the port through
the following possible settings:
Untagged port
Tagged port
Port is not a member of the VLAN
