## Symptoms

- * Running the '`cphaprob state`' command on the cluster members after initiating a failover generates an irregular output.   
  Status of the primary cluster member shows '`Active Attention`'. Status of the secondary cluster member shows '`Standby`'.   

* Running the '`cphaprob -a if`' command on the cluster member generates an abnormal output.   
  This output includes all the interfaces under '`Required Interfaces`' instead of just displaying the interface that is configured with the lower VLAN tag.   

* Running the '`cphastop ; cphastart`' commands on the cluster members temporarily resolves the problem.

## Cause

The '**Monitor all VLAN** ' feature is used.
