Creating and Modifying VLANs

The Þelds immediately below the ConÞgured VLANS list box are used to create
and modify your port-based VLANs. To create a new VLAN:

1.

In the VLAN ID field, enter a unique value between 2-4094. VLAN ID 1 is
reserved for the Default VLAN, and cannot be used.

2.

If desired, enter a name for the VLAN in the VLAN Name field. VLAN names
must be 32 characters or less.

3.

Click the Apply button. The new VLAN will be added to the Configured
VLANS
list box.

Once a VLAN has been created, its VLAN ID cannot be modiÞed. If you wish to
change a VLANÕs ID, youÕll have to delete the VLAN and create a new entry. See

Deleting VLANs

, on

page 2-66

, for instructions on deleting a VLAN. Attempting

to change a VLANÕs ID will result in the creation of a new VLAN with the same
VLAN name.

To modify an existing VLANÕs name, select its entry in the ConÞgured VLANS
list box. The selected VLANÕs name will be displayed in the VLAN Name Þeld.
Modify the displayed name as outlined in Steps 2-3, above.

Deleting VLANs

The VLAN ConÞg window also allows you to delete VLANs (except for the
Default VLAN, which cannot be deleted). When a VLAN is deleted, any ports
assigned to that VLAN will automatically become members of the Default VLAN.
To delete a VLAN from your 802.1Q switch:

1.

Click to select the desired VLAN entry in the Configured VLANS list box.

2.

Click the Delete button. The selected VLAN will be removed from the list box.

NOTE

Unless Enable is selected when a port-based VLAN is initially deÞned, it will be disabled
by default. A new VLAN that is left in a Disabled state will remain disabled until a port
is assigned to it, at which time it will be automatically enabled. If you are changing a
VLANÕs port assignment, the VLAN should be disabled before changing the port
conÞguration. See

Enabling and Disabling VLANs

, on

page 2-67

, for instructions on

disabling VLANs. See

Performing Ingress List ConÞguration

, on

page 2-67

, for

details on completing your VLAN port conÞguration.
