Re: Ignore snmptrap linkup and link down for some nodes

I think that I found the problem.
<mevalue> can not contain expression like [1234678], I will have to spell out every one of them separately.

Subject: [opennms-discuss] Ignore snmptrap linkup and link down for some nodes

Hi,

I have recently installed opennms 21.0 and I was able to ignore LinkUp and LinkDown traps after searching this forum.
However, after I upgraded opennms from 21.0 to 22.0. Now, I can now suppress it anymore.
Here are the code that I use:

  <!-- Drop the linkDown and linkUp traps for IDF devices -->
  <event>
    <mask>
      <maskelement>
        <mename>generic</mename>
        <mevalue>2</mevalue>
        <mevalue>3</mevalue>
      </maskelement>
      <maskelement>
        <mename>host</mename>
        <mevalue>10.[1234678].%</mevalue>
        <mevalue>10.1[1234].%</mevalue>
        <mevalue>10.42.%</mevalue>
        <mevalue>10.51.%</mevalue>
      </maskelement>
    </mask>
    <uei>noc.ucdavis.edu/generic/traps/SNMP_Link_State/discarded</uei>
    <event-label>Discard link state traps for IDF switches</event-label>
    <descr>Discard link state traps for IDF switches.</descr>
    <logmsg dest="suppress"></logmsg>
    <severity>Normal</severity>
  </event>

I put my modified code in front of the
<event-file>events/opennms.snmp.trap.translator.events.xml</event-file>
In the evetconf.xml file, which normally processes the linkup/down traps.

I would like to hear some tips at debugging such problems.  Thank you.
