In ClusterXL, CCP packet "FWHA_IFCONF_REPLY" is sent in broadcast on trusted (sync) interfaces
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;
This behavior is by design.
