Setting Up a VLAN 5-5
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.
TR VLAN Info Setup Screen
To set up a TR-in-FE VLAN, proceed as follows from
the main menu:
1 Use the [Space Bar] to scroll to VLAN.
2 Select VLAN INFO.
3 Press [Return].
The VLAN Info Setup screen appears. See Figure 5-4.
Figure 5-4 TR VLAN Info Setup Screen
4 Select the VLAN that you wish to configure. Enter the
number associated with the VLAN in the VLAN ID
field.
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:
1 Use the [Space Bar] to scroll to VLAN.
2 Select SETUP.
3 Press [Return].
The VLAN Info Setup screen appears. See Figure 5-5.
