Extending VLANs into the ATM Network 8-5
2 If the VLAN is to be connected to an ELAN, select Yes.
If you do not wish the VLAN to be connected to an
ELAN, select No.
3 If there is a LECS controlling ELANs on your network,
it should automatically supply the LES address for the
ELAN, and you should select the LECS option.
Only select the Manual option if:
■ A LECS is not in use on the network, or
■ The LECS is unaware of the existence of the ELAN
to be joined, or
■ You do not wish the LEC to join a LES controlled by
a specific LECS.
If Manual is selected, the LES address field is displayed
on the screen, and you should enter the ATM address
of the LES associated with the selected VLAN/ELAN.
4 Enter the name of the ELAN that the VLAN is to join.
The ELAN must have already been set up in the ATM
network and be operational.
5 Select the APPLY button.
If the LEC associated with the VLAN is active when
APPLY is selected, it will temporarily become inactive
while the changes are applied, and you may
experience a brief loss of communication on that
connection.
