iAP - tftp dump server - always wondered what this did, still do...

    Since I got the first iAP, I've had this line in the config:

    tftp-dump-server 10.10.105.14

     It just sounded like a potentially useful command.

     

    Over many months, I've had firmware upgrades fail and iAP-master-wars and all manner of things go awry and never had a single packet arrive on the TFTP server until I looked today and see that for the last few days, we're getting a string of dump files!!

     

    One of the new iAP275 we installed last week is hollering about something. There are no syslog messages implying anything wrong, no alerts in Aiwave, and nothing of interest in the iAP GUI.

     

    I am sending this same question off to TAC with a copy of the last few files:

    core.<date-stamp>_<time-stamp>.<mac-address>.sapd.3131.Centaurus_45063.tgz

    I'd be interested to know as well. According to the cli guide, it is where it will store core dump files, that's pretty much it.

    Per TAC:

     

    "The dump server is a TFTP server that is used by the AP to dump the core in event of process and kernel crash on the AP.

    The file format is given below:

     

    core.<process name>.<apname>.PID"

     

     

    In our case, the file name is core.20140826_094019.aca31ec0130a.sapd.4804.Centaurus_45063.tgz

    and apparently the "sapd" bit tells us what debugging data to go collect.

     

    Guess I'm glad I've been setting that "just in case"
