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.

5. Type 2 to select VLAN ID (VID) and enter a VID value for the new

VLAN. The permitted range of the VID value is 1 to 4094.

Note

A VLAN must have a VID.

The management software will use the next available VID number on
the switch as the default value. 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, the Sales
VLAN on each switch should be assigned the same VID value.

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 has VLANs using VIDs 2 through 24, the AT-S62 software will
still use VID 2 as the default value for the first VLAN you create 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. If the VLAN will contain tagged ports, type 3 to select Tagged Ports

and specify the ports. If this VLAN will not contain any tagged ports,
leave this field empty.

You can specify the ports individually (e.g., 2,3,5), as a range (e.g., 7-
9), or both (e.g., 2,5,7-9).

7. Type 4 to select Untagged Ports and specify the ports on the switch to

function as untagged ports in the VLAN. If this VLAN will not contain
any untagged ports, leave this field empty.

You can specify the ports individually (e.g., 2,3,5), as a range (e.g., 7-
9), or both (e.g., 2,5,7-9).

When assigning ports to a VLAN, note the following:

ˆ

An untagged port is automatically removed from its current

untagged VLAN assignment when assigned to a new VLAN.
