SNMP trap from ACI not readable

[Networker0]

Hello team,

SNMP is configured in ACI and the SNMP manager is NNMi, when traps are sent from APIC for interface down, the message is not readable, for example, the format below:

"cieLinkDown

1.3.6.1.2.1.2.2.1.1.  = ,.1.3.6.1.2.1.2.2.1.7. =1,.1.3.6.1.2.1.2.2.1.8. =2,.1.3.6.1.2.1.31.1.1.1.1."

Is there a way to resolve this from the APIC side (customize the message format) or maybe add new ACI MIBs in NNMi side?

Thanks

To understand who's guilty (and how) you need to dump the SNMP trap into a PCAP and view.

You can do it on the switch that generates a trap using tcpdump. Provided you're sending using OOB mgmt the cmd could be:

tcpdump -i eth0 udp port 162 -w /data/techsupport/snmp_trap.pcap

You can repeat the same on your NNMI server.

Then you open the packet dump in Wireshark and check 1). if it can parse it and 2). if you see there what you'd expect (as per the MIB reference).
