ATM LEC SETUP This button takes you to the ATM
LEC Setup Screen (as shown in Figure 8-3) which
allows you to extend VLANs into the ATM network.
Extending VLANs into the ATM Network
This section describes how to extend VLANs into the
ATM network. The ATM port can be in one or more
VLANs. Each VLAN is associated with a LEC on the ATM
Module, and each LEC is mapped to an ATM ELAN.
There are two ways to access the ATM LEC Setup
screen:
■
Select the ATM CONFIGURATION option from the
Main Menu. The ATM Module Configuration
screen is displayed, as shown in Figure 8-2 on page
8-2. Select the ATM LEC SETUP button.
■
Alternatively, if you are already in the ATM Port
Setup Screen, as described in “ATM Port Setup” on
page 8-6, you can select the CONFIG button to
display the ATM Module Configuration screen. An
example of the ATM Configuration screen is shown
in Figure 8-2 on page 8-2. Select the ATM LEC
SETUP button.
An example of the ATM LEC Setup screen is shown in
Figure 8-3.

Each time you complete the entry fields for a VLAN
you must select APPLY to apply the changes. As soon
as you select a different VLAN using the VLAN field
any edits not already applied, using the APPLY button,
are lost.
To set up an ATM VLAN:
1
Select the VLAN that you wish to configure. Enter the
number associated with the VLAN in the designated
field. VLAN to LEC mappings are shown in “ATM Port
Setup” on page 8-6. The default VLAN is VLAN 1, the
admin VLAN.
You cannot configure VLAN 15 or VLAN 16 when
these VLANs are being used for Auto-Select VLANs
and Spanning Tree, respectively.
