Configuring an IMA Group
Once you have added an IMA group on your PXM1E, you can configure that IMA group’s parameters.
Use the following procedure to configure IMA group parameters.
Step 1 Establish a configuration session with the active PXM1E.
Step 2 Enter the dspimagrps command to list the IMA groups configured on the current card.

Step 3 To display the configuration information for the particular IMA group that you want to configure, enter
the dspimagrp <group> command. The IMA group numbers are listed in the Ima Grp column. In the
following example, the user displays the IMA group 2.1.
