Adding ATM Traffic Profiles

ATM traffic profiles are stored in the

ATM Traffic Descriptor Configuration Table

window. Each

profile has an index number assigned to it. You use the index number to assign a profile to an
ATM connection.

1

In the

Traffic Type

box, select the desired traffic descriptor type (

UBR

,

CBR

,

rt-VBR

or

nrt-VBR

).

The text boxes to the right display the default parameter values for the selected traffic type.

2

Type the desired information in the text boxes as follows:

3

To activate the profile, click Add. The new profile is assigned an index number and is
displayed in the

ATM Traffic Descriptor Table

.
