I work for an ISP and i'm trying to bring up a IMA group with a CISCO AIM series and a Lucent PSAX IMA CARD. I've done this plenty of times before with regular non AIM routers but I'm having a little problem now.
Little PROBLEM:
-I'm testing Layer 2/Layer 3 with a Redback and i'm getting accross with the occassional packet loss.
-When I debug for some reason i'm getting an "ima group up/down messages".
-I'm also getting an error saying "ATM not active yet"
At the Lucent side, i'm getting cell mismatch errors like crazy but the ima group never drops.
It seems per the description of your post that the AIM is not participating in the clock, can you confirm this? besides do you have any clocking errors? slips? etc? Hope this helps.
Thanks for the info, but still getting the following errors: atmcisco#debug atm errors ATM errors debugging is on atmcisco#term mon atmcisco#

**AT this point im telling the cisco router to
-Pull the clocking from the psax (t1 0/2/0 the primary source for clocking)
-AIM1 and WIC 2 are participating in the "network clocking".
***THESE ARE THE MISMATCHED CELLS ON THE PSAX3200 THE 2 IMA ATM PORTS ARE CONFIGURED THE FOLLOWING WAY: ((NOTICE THE LOCAL TIMING ))
You may wish to investigate Cisco TAC Case K16466674.
ATM Advanced Integration Module (AIM) modules installed in
2600/3600/3700 routers require some unique clocking configuration to allow it to function properly. Failure to configure it properly results in errors on the T1/E1 controller and Inverse Multiplexing (IMA) links, as well as groups that flap continuously.
