My ASA has been configured with several snmp collectors. one of the collector does not seem to work. Is there a command to check if the snmp packets have been sent for that specific collector? Thx

Hi,

You can use SNMP Informant;

For general diagnosis of networks, Wireshark is the best tool;

Is it possible to see it from within the ASA with a command?

Since other collectors are receiving the snmp so it means ASA is working fine...what collector is having issue?

I have this command "snmp-server host Internal 192.168.100.13 community mystring" like the other snmp statement for the other collector.  My collector does not see any snmp traffic. I did a show command that show snmp packets. But it is for all the packets sending out. I'd like to know if there is a command that show the snmp packets only for 192.168.100.13. Thx

Thanks for the update. I doubt it is possible the way you are trying to do. However using wireshark and placing it next to ASA will show if packets are sent to the specific collector at 192.168.100.13.

I personally think that on the collector at 192.168.100.13, something is blocking the snmp traffic. Possibly it could be the windows firewall incase its active or may be AV. Incase it some linux device then may be iptables.
