    Description

      Hello,

       

      I have a stack of switches Cisco C9500.

      Observium has an active alarm about "Stack is redundant"(attached screenshot) but stack is full redundant.

          [OBS-3569] Alert Stack is redundant

          This is stable 10874, you'll need to wait for the changes to be pushed to stable to get them

          Ignore what SVN says, the version is at the bottom of the web ui.

          Hi Mike,

          I rediscovered and delete/add  the device, the results are same.

          #svn update
          Updating '.':
          At revision 10915.

           

          Please see the attached screenshot.

          rediscover device or wait for next cron rediscovery.

          Hello Mike,

          I have r10911(stable version), the problem still persists.

          Fixed in r10884.

          Correct stack status already detected by
          CISCO-RF-MIB::cRFCfgRedundancyOperMode.0 = INTEGER: hotStandbyRedundant(8)

          There is just incorrect status description, not stack redundancy. I will try to find correct Oid for check Stack redundancy status.

              SYNTAX          TruthValue
              MAX-ACCESS      read-only
              STATUS          current
              DESCRIPTION
                  "A value of 'true' is returned when the stackports are
                  connected in such a way that it forms a redundant ring."

          The device is reporting this OID as false. It's sometimes difficult to get sane defaults for these sorts of things.

          SNMP STATUS[TRUE]

          Just ignore it.
