Setting Up a VLAN

This section describes how to extend VLANs into the TR-in-FE network. A TR-in-FE port can be in one or more (up to 16) VLANs.

Each time you complete the entry fields for a VLAN you must select APPLY to invoke the changes. As soon as you select a different VLAN using the VLAN field, any edits not already applied are lost.

Included in this screen are the following fields:

VLAN Name—Name assigned to identify each (up to 16) VLANs.

802.1q VLAN ID—A 12-bit ID used to identify a particular VLAN’s frames for routing across FE media. This ID defines which frames should be received and forwarded to a VLAN via the TR-in-FE module. If TR ports on separate boxes are to be connected via TR-in-FE, then this parameter must be identically configured on both boxes. By default, all TR ports are assigned to VLAN 1, and the 802.1q VLAN ID is identical to the VLAN number assigned to the box.

TR VLAN Setup Screen

Use this screen to assign VLANs to the TR-in-FE port, and to associate a backbone port (the place to which unknown unicasts are forwarded) with each VLAN.

To set up, proceed as follows from the I/O Module menu:

1Use the [Space Bar] to scroll to VLAN.

2Select SETUP.

3Press [Return].

The VLAN Info Setup screen appears. See Figure 5-5.
