Hello all,
I'm using a cisco 2811 IOS c2800nm-entservicesk9-mz.124-5.bin with 4 VWIC-2MFT-E1 modules connected with eight E1 atm link configured with 2 ima groups.
Even if i've replaced wic and cables i continue to receive these error:
*Aug 29 13:50:19.614: %ATM_AIM-5-CELL_ALARM_UP: Interface ATM0/2/0 lost cell delineation.
*Aug 29 13:50:19.630: %ATM_AIM-5-CELL_ALARM_DOWN: Interface ATM0/2/0 regained cell delineation.
*Aug 29 13:50:20.130: %ATM_AIM-5-ACTIVE_LINK_DOWN: Interface ATM0/2/0 of IMA Group ATM0/IMA1 is now inactive.
*Aug 29 13:50:20.130: %ATM_AIM-5-ACTIVE_LINK_CHANGE: IMA Group ATM0/IMA1 now has 3 active links.
*Aug 29 13:50:20.158: %ATM_AIM-5-ACTIVE_LINK_UP: Interface ATM0/2/0 of IMA Group ATM0/IMA1 is now active.
and for all the interface grouped to the same ima group.
here the configuration:

These two links are provided by the local incumbent but i don't know if they are attached to the same device;
If the two links are connected to a different device, is it possible that the second link use le clock of
the first one losing delineation?
Thanks in advance
