SNMP Trap for Nexus 7K

I have my Nexus 7K where i have configured the below SNMP command.

snmp-server enable traps ospf state-change

When there is OSPF neighbor change like state change like neighbor down the Nexus 5K logs shows the output.
These trap needs to be received by my SNMP Manager which needs to generate alert.
From the SNMP manager we could not find any trap being received from the Nexus 7K for the OSPF state change.
I would like to understand the below.

- Is there any additional configuration i need to configure in the Nexus 7K.
- Is there any specific MIB/OID which needs to be installed in the SNMP Manager. If yes what is that ?

Any inputs.
1) Trap destination - IP of your trap collector
2) and search for OSPF
You should check if OID received by SNMP manager is in downloaded MIB file and also add all include files
Is that the only SNMP command you have configured?   Do you have any "snmp-server host" configured?

Yes ofcourse i have configured the snmp-server-host pointing to my SNMP manager.
Do you receive any traps from cisco at your trap collector?
Just checking, sometimes the simplest possibility ends up being the problem, so I try to start with the basics.

If your not receiving any traps and you can ping your trap receiver from the switch then I would suggest you setup a monitor session and a run packet on the trap collector.  This way you can verify the trap is leaving the switch and you see if it is making it to the trap receiver.

I would expect that your trap receiver would keep the alert  even if it it did not have the MIB, it may not display a human understandable description, but it should keep it.  Depending on how you have it configured it may or may not send an alert.  Do you have it sending an alert on every trap it receives?

No it is not configured to send alert for every trap it receives.
what should i check or what should i look for in the SNMP manager server to ensure that the trap for the OSPF neig change has been sent or not.
What exactly i need to look for in the SNMP Manager server.
First you tell SNMP Manager server vendor and version numbers.
