SNMP v3 Problems in conjunction with CA Spectrum
Hello guys, We are actually experiencing some “connection” problems with some F5 LTM’s on our monitoring system (CA Spectrum). The LTMs are modeled in the monitoring system and are monitored via icmp/snmpv3. The LTMs are running in HA Mode and the problems only occurs between the HA partners. Sometimes Spectrum loses the connection to the “Management Agent” of a device which is in CA speech a not working SNMP connection. In other cases (and other devices types) this usually had something to do with the SNMP EngineID which was by accident or whatever identical. In these cases we edited one EngineID and reset the device in Spectrum and everything was fine. But on the LTMs it looks a bit more complicated. They’re running fine for a while and suddenly Spectrum loses the connection to the management agent. I reset the settings in spectrum and it will work again for some time. I have checked the SNMP Settings on the LTM`s twice, done everything like this SOL6821 says and I also checked the EngineID s that are used by/in spectrum and they are different… like it should. What I noticed is that this always happens when I sync the devices over the GUI with a check on “overwrite configuration”. Is there any connection between the sync processes of HA devices and the snmp agents? Has somebody made experience with similar problems? Thanks and Regards, eneR
