Hi, I have configured SNMP and NMS is able to monitor ASA for a few minutes but after that it times out and the NMS says it can not connect on port 161. I can not run snmpwalk either, however if I try it from a different host, I can run snmpwalk. I have checked the logs and the following is what I see.
I am not using the management port but rather the inside interface and It seems that ASA is only allowing one NMS to connect to it at a time, though I have configured two servers.
snmp-server host inside 172.21.40.55 community ***** version 2c
snmp-server host inside 172.21.40.41 community ***** version 2c
snmp-server community *****
snmp-server enable traps all
Any ideas what is going on?
