• Manual entry if the ATM switch does not support ILMI.

Step 8. Set the UNI Version ﬁeld to the appropriate value for your ATM switch.

If you intend to use the ABR trafﬁc type on SVCs, your ATM switch must

be UNI 4.0 compliant and you must also set the UNI Version ﬁeld to

UNI 4.0.

NOTE You will not be able to open SVCs if the UNI version conﬁgured on the

ATM adapter is not the same as the UNI version conﬁgured on the

switch port the adapter is connected to.

Step 9. If you set the Network Prefix option to Manual entry in step 7 above,

then enter the ATM address network prefix here.

Step 10. Select the Advanced Configuration button, to access the advanced

parameters (see the SAM online help for the parameter descriptions).

Step 11. Verify the following:

• That the ATM Layer is set to the correct VPI/VCI range and that it

matches the VPI/VCI range on the switch—check your switch to ﬁnd

the VPI/VCI range.

• That the ILMI VPI/VCI range is set to 0,16 (the ATM Forum

default).

Step 12. Click on the OK button to activate the ATM adapter conﬁguration.

NOTE You must click on the OK button to enable the ATM adapter’s

conﬁguration, even if you do not change any of the default settings. If you

select Cancel, the conﬁguration is not implemented and the ATM

adapter remains unconﬁgured.

Step 13. Conﬁgure at least one network interface, which can be either of the

following:

• Classical IP (see Chapter 3, “Conﬁguring a Classical IP over ATM

Interface over an ATM Interface,” on page 23).
