VLAN ID
The VLAN ID is used to identify data frames that originate from, and are intended for, the
ports assigned to the VLAN. Up to 64 VLANs may be created, with VLAN IDs ranging
from 2-4094. The VLAN ID is combined with the port’s identification (e.g., module X
port X) to form the Port VLAN ID (PVID). VLAN ID 1 is reserved for the Default VLAN.
VLAN Name
An optional 32-character VLAN name may be assigned to a created VLAN. The Default
VLAN is assigned the name DEFAULT VLAN, which cannot be changed or deleted.
Admin Status
This field indicates whether the VLAN is enabled or disabled. Unless Enable is selected
when port-based VLANs are initially defined, they are disabled by default. The Default
VLAN cannot be disabled.
Creating and Modifying VLANs
The fields immediately below the Configured 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 modified. If you wish to change a
VLAN’s ID, you’ll have to delete the VLAN and create a new entry. See Deleting
VLANs, below, for instructions on deleting a VLAN. Attempting to change a VLAN’s ID
will result in the creation of a new VLAN with the same VLAN name.
To modify an existing VLAN’s name, select its entry in the Configured VLANS list box.
The selected VLAN’s name will be displayed in the VLAN Name field. Modify the
displayed name as outlined in Steps 2-3, above.
NOTE Unless Enable is selected when a port-based VLAN is initially defined, 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
VLAN’s port assignment, the VLAN should be disabled before changing the port
configuration. See Enabling and Disabling VLANs, on page 2-75, for instructions on
disabling VLANs. See Performing Ingress List Configuration, on page 2-75, for details
on completing your VLAN port configuration.
