Upgrading X460 from version 15.5.3.4 to version 16.2.2.4 using Netsight version 7.1.1.9

    We have found that downloading XOS to a x460 from netsight ( or its latest naming convention ) we loose remote management and SNMP traffic , to that switch, that basically causes our management systems ( PRTG and Netsight ) to start generating alarms.

    The update is successful once access is returned by confirming in the log etc.

    We have manually upgraded some X480 units ( console/telnet connected and a TFTP server ) and we do not see the same scenario ie. No alarm generated. Logs look OK .

    So the question is:
    Is netsight working as expected .. does netsight , uses different commands or process that have an effect on the CPU.

    Basically is this expected behaviour or not.

    Did you restart the X480 so the new software is active or could the switch do that without a reboot?

    As you'd see per default "Restart Devices After Upgrade" is set.
    That restart/reboot would explain the alarms that you get.

    Hi

    The basic scenario , is that we were uploading code to the switch for a later timed reboot.

    What we found when using Netsight for this upload we lost communication while the upload was preformed ( I have assumed high CPU while downloading image ) stopped the switches response to PRTG and Netsight.

    While performing the same action , this time not using Netsight as the tftp server, we experienced no alarms from our management tools.

    I hope that clears up the scenarios we were encountering.
