EXOS port link flap detection/alarm before version 22.2

  • 1.  EXOS port link flap detection/alarm before version 22.2

    Hi all,
    I was wandering if anyone has the same "request" a costumer asked me:
    to be able to detect link flapping of certain ports.

    is there any UPM script we can use?
    or any filter/easy task we can configure on the extreme management system?

    Please keep in mind we're using EXOS switches, mostly x460, NOT g2,
    and some X440-G2

    I know there's a new feature on 22.2 to easily detect port flapping,
    but,
    22.2 is NOT compatible with x460-g1,
    and still it's NOT the recommended version for X440-G2 ...

    last but not least ...
    I'm talking about "general" links,
    that can be with other vendor devices,
    or even with user devices,
    so I cannot use ELSM ...

    thanks in advance

    best regards

    Stefano

    I use siem for monitor port flaps. Rules are very precise, and it wokrs very well, and look like that:
    when BB:link-up match at least 20 times in 5 minutes after BB:link-down match with the same Devices port

    but you use SIEM from extreme networks, or also from other vendors/solutions?
    is there any way to specify a range of ports, and get an alert when one of that range starts flapping?
