Michael, We ran into a similar issue a couple of times, it ended up being related to an firewall that we had filtering all of our traffic. The only way we determined this after much troubleshooting with CA was to sniff for the packets, determine what the normal behavior was and then compare what we were seeing occasionally on most landscapes. We were sniffing on both sides in order to be sure of packet delivery etc. We narrowed down a few devices where it was occurring most often and then watched them stop responding to polls, spectrum trying to reach it through snmp & icmp a few more times and then the alarm being asserted on that model. The machine was then back up and running and we saw Spectrum send another snmp packet...no response...icmp packet...no response....a few more times and the alarm was still there and spectrum went back to its polling schedule when a device is down(as it indicates in the manuals as the process) We would then do a manual poll and that would clear the alarm. When we did the manual poll it was working fine but still not every time. So ultimately I requested that since this traffic is monitoring most of our network devices and the firewall was running out of internet resources tracking where all of our packets were going, it needed to be as unfiltered as possible, the network team then set things up so our traffic did not pass through a firewall before getting to the various networks that we monitor and that problem disappeared almost immediately.
I have not seen this behavior on 9.1 H12. It might not be the same problem but sniffing for the traffic I believe will give you the best idea of what is going on in your environment.

This was a problem for us on v8.1 (Windows), however v9 (also on Windows) seemed to help it. We're up to 9.1.2 H12 now. Recent forum posts indicate that 9.1.3 H17 is also available now.

Troubleshooting: - Confirmed the models attributes "Poll Interval" was set to 300sec - Confirmed Poll Port Status Device was set to Yes Anyone have any ideas on how to resolve this issue? -- Michael Lopez E-Mail: [email protected] --- To unsubscribe from spectrum, send email to [email protected] with the body: unsubscribe spectrum [email protected] --- To unsubscribe from spectrum, send email to [email protected] with the body: unsubscribe spectrum [email protected] -------------------------------------------------------- The information transmitted in this email and any of its attachments is intended only for the person or entity to which it is addressed and may contain information concerning Cablevision and/or its affiliates and subsidiaries that is proprietary, privileged, confidential and/or subject to copyright.
