3Enter the LECS access type. Choices are lecs and manual.

If you choose LECS as your means of joining an ELAN, and another CoreBuilder system provides LES and BUS services, you must update the directly attached ATM switch LECS with the ELAN name and the corresponding LES address.

4Enter the name of the emulated LAN to which you are adding the client, or press Return to choose the default ELAN shown in brackets. The ELAN name may contain a maximum of 32 characters.

5Enter the maximum transmission unit (MTU), also known as maximum frame size. Choices are Unspecified, 1516, and 4544.

The system supports Unspecified Bit Rate (UBR) only.

All LECs within the same emulated LAN must have the same MTU size.

Enter Unspecified to allow the LES to select an appropriate MTU size.

6Enter enable for the enable state for the next reboot.

7Repeat steps 1 through 6 to define other LECs.

8Enable STP to eliminate potential bridge loops. From the top level of the Administration Console, enter:

bridge stpState enabled

9Reboot to enable all newly defined LECs.

Sample procedure:

Select menu option (atm/lane/lec): define

Select ATM port [1]:

Enter LEC access type (lecs, manual) [lecs]:

Enter Elan Name []: Elan_1

Enter Elan MTU Size (Unspecified,1516,4544) [Unspecified]: Enter Enable State for next reboot (disable, enable) [enable].

You must REBOOT to be able to enable a newly created LEC.
