More than one sync interface defined-checkpoint-all
Vendor: checkpoint
OS: all
Description:
ClusterXL works best with just one sync interface. To achieve redundancy, interface bonding is recommended. indeni will alert when more than one sync interface is used.
Remediation Steps:
Read Valeri Loukine’s post on the subject: http://checkpoint-master-architect.blogspot.com/2014/05/notes-about-sync-redundancy.html.
How does this work?
By using the Check Point built-in “cphaprob” command, the information is retrieved.
Why is this important?
ClusterXL defines a certain number of secured (sync) interfaces which are required to be up for the cluster to be considered healthy. If there are less than these actually up, the cluster is not in a healthy state and traffic flow may be affected.
Without Indeni how would you find this?
An administrator could login and manually run the command.

To check the healthy state of the cluster interfaces important factor for Cluster stability and redundancy

By Checking the input of Check Point clusterXL command "cphaprob -a if"

cluster-vip:
why: |
This is the list of cluster virtual IP addresses also called floating IP adddresses for the cluster interfaces.

clusterxl-ccp-mode:
why: |
ClusterXL can operate in different modes, multicast or broadcast. All members of the same clusters should have the same setting to ensure redundancy works correctly.

To check the status of the "Sync" interface is up
