Hi Wolf , 

  Thank you for your answers .  

Could you kindly elaborate on point 3  . I understand that the multicast-port is used for multicast messages which form the foundations of the cluster , but am still unclear as to what we need the port 55200 for .   

Also a few further add-on questions :- 

4> Let us say that I have 2 clusters running with different multicast address + port combinations ... in case the cluster names  are  the same , will there be an issue ?   
5> The cluster names are the same as the names ( output of the hostname command ... assuming a Unix box ) of the first node starting the cluster right ? 

6> Assuming that running more than 1 JBOSS cluster on the same network is a common requirement , what are the default methods that are generally used to guarantee unique multicast-address + port combinations ?  
  In our case we were thinking about setting the last 3 octets of the multicast address as the same as the last 3 octets of the IP address of the first node of  the cluster   ( assuming locally assignable multicast addresses belong to the range 239.0.0.0  -  239.255.255.255  )     .
