Enabling L2TP on an Existing ATM Interface

To enable L2TP on an interface with ATM and IP already enabled, you can enable L2TP in two ways. If your interface uses a COM connector, complete the tasks in the following table. If your interface uses an ATM connector, go to page 2-10.

			Site Manager Procedure

	You do this			System responds

	1.	In the Configuration Manager window,		The Edit Connector window opens.
		choose a WAN connector.

	2.	Choose Edit Circuit .		The Circuit Definition window opens.

	3.	Choose Group Protocols .		The Group Protocols menu opens.

	4.	Choose Add/Delete.		The Select Protocols window opens.

	5.	Choose L2TP, then click on OK.		The L2TP Configuration window opens.

	6.	Set the following parameters:
		• RADIUS Primary Server IP Address
		• RADIUS Primary Server Password
		• RADIUS Client IP Address
			Click on Help or see the parameter
			descriptions beginning on page A-5.

	7.	Click on OK.		The L2TP Tunneling Security window
				opens.

	8.	Click on OK.		The L2TP IP Interface List window opens,
				followed by the L2TP IP Configuration
				window.

	9.	Set the following parameters:		Site Manager displays a message
		•	L2TP IP Interface Address	alerting you of the time delay to create
		•	Subnet Mask	the L2TP tunnel circuits.
			Click on Help or see the parameter
			descriptions beginning on page A-11.

	10. Click on OK.			You return to the L2TP IP Interface List
				window, which displays the IP interface
				address and the subnet mask. A
				message window opens that reads, L2TP
				Configuration is completed.

	11. Click on OK.
