ASA Teardown ICMP/SNMP requests sent from our SNMP Server.

[hi.sadiki]

Hello guys,

I need your help for this case please.

I am not able to supervise  (Centreon) my ASA Firewall device. 

I see on ASDM monitoring UI   that the The ASA receives SNMP and ICMP request from Centreon supervisor server.

then, the ASA doesn't respond and  teardown the ICMP and SNMP connections. 

Attached to this is why i see from ASDM !

I have configured my ASA with the right snmp-server commands : 

snmp-server host MGMT-OOB 10.250.6.18 community ***** version 2c
snmp-server location XX

thanks for your help,

Hi,

   It looks like there was traffic over the SNMP session, and the session was closed after 2 minutes and 5 seconds, so most probably after the UDP default idle timeout of 2 minutes. As for the ICMP session, it looks the session is teardown after 2 seconds which matches the default ICMP connection timeout. So it all looks legit.

Regards,

Cristian Matei.
