Totem as is implemented in corosync is not designed for large scale rejection of messages because administrators want unique clusters on the same multicast address and port. Corosync will have very poor performance characteristics in this model and spew a ton of warnings and also not scale particularly well. Best to get the cluster admin to configure the cluster's ports. I really cannot recommend at all using the secure key to uniquely identify clusters.
