follows:
cnfatmimagrp -grp <bay.group> -sps <PayloadScramble> -ais <aisMode>
In the following example, the user enables payload scrambling and AIS on the ATM IMA group 14 on
the PXM1E in the lower bay.
Unknown.7.PXM.a > cnfatmimagrp -grp 2.14 -sps 1 -ais 1
Table 9-37 describes the parameters for the cnfimagrp command.
Enter the dspatmimagrp <bay.group> command to display whether AIS and payload scrambling are
enabled or disabled for an IMA group, as shown in the following example:
