SNMP Problem

I've been using SNMP traps for about 15 months on my F5 unti v9.4.2. I had it sending traps to my WUG server, so I always knew when a node/pool member/logins fail/config sync etc, via an email alert from WUG. It was great! All of the sudden the WUG instance is no longer receiving traps from the F5. My question is, is there a way (command or something) to see if the F5 is actually generating the SNMP trap and sending it? I've removed the snmp settings, and re-added to no avail. Support had me do a full_boot on both units. Please help

 

 

Thanks

    You can run a tcpdump on whichever vlan the unit should be sending traps out on looking for the SNMP port (162 unless you've changed it). 

     
 tcpdump -ni  port 162

    If you are using the mgmt port to send to the SNMP destination then use eth0 instead of the vlan name.

    This should at least show whether the unit is trying to send traffic out.
