Resilient Link—Maximum number of T1/E1 links within the AIM group that can go down and the AIM
group will still remain active.
In the following example, the number of resilient link is changed to 2 and the differential delay to
100 ms. Enter the following command:
cnfaimgrp 1 100 2
Display the AIM Group
The command is dspaimgrp group number.
AXIS18.1.13.IMATM.a > dspaimgrp 1
Sample Display
Explanation of some of the parameters:
Local AIMUX ID—Indicates the IMA-ID in use at the local end.
Used in AIM state machine to communicate with the other side entity.
Remote AIMUX ID—Indicates the IMA-ID in use at the remote end.
Observed Diff delay—The observed differential delay is between the two different physical links in the
IMA group.
