How to ensure that the network synchronization works properly

Upon troubleshooting a VPN tunnel that was not being established, I came across the following error:

"Packet is dropped because an IPSEC SA associated with the SPI on the received IPSEC packet could not be found."

 

While led me to sk19423:

 

Since the affected gateway is indeed a cluster member I would like to ensure that the synchronization network works properly to see if the scenario above applies.

My question is therefore, is there another way of checking the sync network other than running the following commands:

cphaprob -a if

cphaprob syncstat

fw ctl pstat

Might be worth noting that the gateway in question also happens to be a virtual instance.

Many thanks in advance.

You could run "show routed cluster-state detailed" to check if your cluster is flapping....
