I must be missing something in the config as this is happening on multiple ASA's. I have the following config in place and not receiving any traps on our management servers. I don't even see the Trap PDU's increasing in the snmp-server statistics. Any suggestions and advice is much appreciated.

You are missing the famous "snmp-server enable" line.

You have all the enable on specific feature but didn't globally enable snmp

Hope that resolves the issue.

I did put this command in but I believe it's already on by default as you will only see the "no snmp-server enable" listed in the running config. Either way were still not getting or sending traps from these firewalls. Any other suggestions?

Are you able to ping the snmp servers from the firewall? Is the snmp server subnet directly connected to the firewall, or multiple hops away? Another thing to note is between the ASA and the snmp servers, are there any other firewall, or ACL that might be blocking the snmp traps?

If you run packet capture on the ASA firewall inside interface, are you seeing the snmp traps being sent out?

Lastly, what does the output of "show snmp-server statistics" show?
