Symptoms
Output of "cphaprob state" command shows that cluster member is "Down".
Output of "cphaprob list" command shows that Critical Device "Active Interface Check" reports its status as "problem".
Output of "cphaprob -a if" command shows for one of the interfaces (ethX) "Inbound: UP Outbound: DOWN:".
Output of "ifconfig -a" command shows interface called "brS-ethX", which is not a physical interface and was not created by the administrator.
Output of "cphaprob state" command also shows:
- On one cluster member "Active/Active in Bridge mode"

Cause
Interface ethX is configured in Monitor Mode, which is not supported in cluster - refer to "Limitations" section in sk101670 - Monitor Mode on Gaia OS and SecurePlatform OS.
