Important Note: Based on the reports from the field and multiple tests in the lab, the use of more than one Synchronization Network for redundancy is not supported for the following reasons:
By design, the Delta Sync traffic is duplicated on the sending cluster member on all the configured Synchronization Networks (the receiving cluster member checks all received Delta Sync packets and discards the packets that were already processed on one of the Synchronization Networks). This increases load on the CPU on all cluster members.
By design, if a cluster interface goes down (from cluster point of view), the member will go into “Down” state. This applies to Sync interfaces as well. Meaning, configuring multiple Synchronization Networks does not provide 100% sync redundancy.
Multiple Synchronization Networks are not supported in VSX.
Note: The ability to configure multiple Synchronization Networks in a cluster object will still exist in SmartDashboard for unique special cases where the cluster administrator is unable to create Bond interfaces.
