ANM 5.2.1 Device Down False Alarms

[Akhtar Samo]

Hello all,

I am just checking if anyone out there is facing false alarm issues with ANM 5.2.1. Basically ANM is sending device down (ACE-30 module) messages occasionally, but in real the device has never went down.

I haven't found any bug related to this issue. Please share your experiences with ANM 5.2.1 ?

Akhtar,

Several issues can be at play here.  Device status is checked by the ANM via snmp polling, logging into the ace and running certain commands either via ssh or xml-agent tcp port.

In the past what could cause this type of issue is network connectivity between the anm and the ace on snmp,ssh,xml-agent ports is broken.

Also if the anm fails to login into the ace, the device will be reported as down,  I would check this expecially if the ace is configured to authenticate via an ACS server running releases older than 5.x.

If all fails, I would open a tac case on this and provide a lifeline from the anm, we should be able to dertermine a reason for this failure in the logs.

Thanks

Is there anyone out there running 5.2.2 facing the same issue ?

Yes, me. On 5.2.2 and just a couple of hours ago, the passive sent this:

I upgraded from 5.2.1 to 5.2.2 around 10 days ago, but got the False alert today. It seems the problem is not fixed in 5.2.2.

How are you taking this up further ?

Well if I hadn't that many Cases (reported and unreported) with Cisco Products I would open another Case. But I just don' thave the time.

Still trying to fix snmp health probes in ANM.

Maybe later if it gets more annoying.

Had this issue in 5.1 but has since stopped in 5.2. No reason for it.
