  • 1.  snmptd probe : Alarms are not showing interface name and number

    Posted Dec 06, 2016 08:10 AM

    Hi All,

     

    Configure the snmptd probe to trigger an alarm for an incoming SNMP-TRAP. As per configurations we are getting alarms but alarms are not showing correct interface name and number instead of that its showing numeric value.

     

    For eg : Interface 436301824 is down.

    Actually it should get as interface e1/0 is down.

     

    Probe Version - snmptd 3.22

     

    Can anyone suggest how this can be fixed to get correct interface details?

     

    Regards - Ripple

    The numeric value that you're seeing is ifIndex which is part of the standard definition for link up / link down traps from devices.  The only way you'll be able to get the ifName, which appears to be what you're looking for, is to have a mapping and/or lookup between ifIndex and ifName.  Are these interfaces being polled by SNMPCollector as well or are you strictly receiving traps?

    Thank you for the information's Robert.

     

    Yes, these interfaces are also polled by the snmpcollector. But as snmpcollector poll and get data & there are more chances of missing interface down alarms, so planning to alert on traps.

    OK.  I wasn't suggesting that you rely strictly on SNMPCollector polling to determine up/down status of an interface but rather that SNMPCollector provides the information that relates ifIndex with ifName, ifDescr, ifAlias, etc. for an interface:

     

    Hopefully, someone else can chime in on where/how you can do that look up and place ifName in the message instead of ifIndex.
