In ClusterXL, CCP packet "FWHA_IFCONF_REPLY" is sent in broadcast on trusted (sync) interfaces
Symptoms
  • The ClusterXL Control Protocol (CCP) on the cluster members uses multicast mode by default, because it is more efficient than broadcast.

    However, the CCP packet “FWHA_IFCONF_REPLY” is still sent in broadcast mode on trusted (sync) interfaces.

  • Cluster debugs shows as below: ;21May2018 14:59:25.448615;[cpu_12];[fw4_1];CPHA: multicast ether not found for eth1-04.324, using broadcast CCP; ;21May2018 14:59:25.448616;[cpu_12];[fw4_1];CPHA: multicast ether not found for eth1-04.324, using broadcast CCP;
Cause

This behavior is by design.
