SNMP problem

SergioHV — Wed, 30 Aug 2017 15:51:26 GMT

Hi everyone

I have a palo alto device with snmp configuration to send snmp packets when something happen (for example when an interface is down or up), the problem is when an interface is down the snmp server does not see snmp packets and if I make a packet capture I only see the next

My palo alto device is 10.19.160.205 and the snmp server is 10.4.150.14 but I see packets with 31.1.1.1.6.9 is this the oid?

If an interface is down is not suppose the oid 1.3.6 or something like this?

hope someone can help me

Thanks

The oid 31.1.1.1.6.9 is a polling request from your snmp manager not a trap. The only traps here are the system uptime from the PA to the snmp manager. This validates that you have the trap configuration setup since they are being sent and seen.

But you are saying you dropped a link in this period. So there is no link down trap here being sent. You do need to enable traps for policies and alerts but my understanding is that standard traps like the link down should be visible as soon as traps are enabled. So there may be some kind of bug here.
