iMC Alarm Trap Name: The device correctly responds to poll packets

  • 1.  iMC Alarm Trap Name: The device correctly responds to poll packets

    Posted 15 days ago

    5900AF stack with satellite cabinets (various HP/Aruba 2920/2930/6300) connected via OM4 fiber 10Gb original GBICs on both ends

    From iMC I get alarms:

    Trap Name:  The device does not respond to poll packet

    That lasts from 10 sec to 1 minute

    It affects each/any cabinet (not all of them at the same time)

    And it must be true, because at the same time I receive notifications from a service that monitors devices on another VLAN that these devices are not available

    Again for a short time duration

    Almost like the satellite switches getting disconnected, then they come back & such error might not appear for day or two for the particular location

    I cannot make any sense out of it, because it is all connected to different ports, going via different physical routes, connecting to different satellite models

    The only constant is the 5900AF stack itself (hence posted here)

    Anybody any idea how to start investigating it?

    Thanks
