Using ASA management interface for SNMP and NetFlow traffic

[donohoecompanies]

We have two ASA 5525Xs who's management interface is on our OOB management network (172.16.8.0/22). Until now, the ASAs were sending SNMP (for port traffic) and NetFlow traffic to a server (172.16.4.45) on one the ASAs standard interfaces (172.16.4.0/22). We now want to move that traffic to the management interface and send it to a new server (172.16.8.40) on the OOB management network.

We've added the following entries to the ASA:

snmp-server host management 172.16.8.40 community secret

flow-export destination management 172.16.8.40 9995

flow-export event-type all destination 172.16.8.40

However, the communication between the new server and the ASA just isn't working. No NetFlow traffic is being sent and SNMP requests from the server to the ASA go unanswered.

Is there something I'm missing to get this working?

Do you have a route configured for the management interface to reach the snmp/netflow server? It will be helpful to post the following outputs:

show route

show nameif

show ip

You can also use ping tcp command to check and confirm connectivity.
