hi, 

Well, cvd is commvault deamon. As you can have multiple Commvault components deployed on the same server, they have to be able to communicate with each other.

What do you expect to see ? ports 8400-8402 ?

There are many ports used by Commvault components, and you would surely understand that they’re different. :wink:

Hi @Ayman Seyam ,

The process itself can attach to Dynamic Ports, For details refer here: 
https://documentation.commvault.com/11.24/expert/8572_tcp_ports_used_for_services.html#dynamic-ports

To restrict services binding to only open ports, you can refer here:
https://documentation.commvault.com/11.24/expert/7353_binding_services_to_open_ports.html

 

Best Regards,

Michael

As @Laurent mentioned, Commvault is made up of many services and executables - they all talk to each other over TCP/IP whether local or remote. In your case those are local processes communicating with each other (the source/dest IP is the same).

You can restrict port usage across a network down to a single port in a single direction if needed using network topologies.

i think i am restricted ports that commvault uses MR Expert
 why still used ports in range 50000 ?

@Ayman Seyam , are you sure the ports in that range are being used for data transfer?  Unless I am misreading, those seem to be used by Java, not cvd.
