XMC Alarm Action SNMP Trap instead of SNMP Inform

Thomas_Gfeller — Tue, 29 Sep 2020 20:47:22 GMT

Hey there

I would like to trigger an SNMP Trap if a certain Alarm in XMC rises, so i choose the “Trap Action” in the desired Alarm. So the problem now is, that XMC sends a SNMP Inform Message and not a Trap defined in the SNMP Standard. Is there a way to change that?

Thanks

Thomas

When you go to select the Action> Trap action, you should see a window pop up to configure the trap. If you have selected SNMP credential in the form of SNMP V3 inform, then you’ll see those SNMP inform packets. If you select SMNP v1 or v2, you should see trap messages. Here is a screen shot of the area I’m referring to:

Hi Sam

Thanks for your reply. i was able to test it. So i get to the point that only v1 sends a Trap message, v2 and v3 are sending Inform Packets. I took a print screen of the different packets captured by wireshark.

Thanks

Thomas

No worries Thomas, easy to fix! For the traps, just so I’m clear, you’re looking to see traps for v2 and v3 as well as v1?

Hi Sam

We would prefer traps with v3 as everting else is v3. But if its by design that only v1 sends Trap Packet, we can configure a Profil only for sending v1 traps.

I discovered the same behavior a while ago as described by Thomas. I wanted to bring some reliability mechanism to trap actions with the inform acknowledge. But XMC does only send the trap once when the actions is triggered, even if there’s no snmp inform ack from the remote system. I don’t know why they have chosen to use snmp informs.

Thanks for clarifying for me Thomas, it looks like we can only send inform packets via v2 and v3 per this KB:https://extreme-networks--c.na101.visual.force.com/apex/KCS_QA_Internal?srKp=ka2&id=kA22T000000XZkv&srPos=0&lang=en_US

I’m sorry I don’t have a better answer for you here. I might suggest reaching out to your sales engineer to file a feature request to see if we can get that changed in a later release. If you’re unsure who to reach out to for your sales engineer, please let me know and I’ll email that information directly to you.
