Modify TCP ports for snapmirror?

[garyfritz]

My client has an application that uses some of the same TCP ports that Snapmirror uses.  Is it possible to change the ports that Snapmirror uses?  E.g. could Snapmirror run on ports 12000, 12104, and 12105 instead of the normal 10000, 11104, and 11105?  I don't see any evidence from the docs that it's possible, but ...

It does not seem like you can. Looking at the doc below, page 16 where it talks about the firewall requirements, it does not state that you can change the TCP ports from the 10000, 11104, and 11105.

Hi garyfritz,

The port numbers are set by default and do not change.  Ports 10000, 11104, and 11105 are the same port numbers used for inter-cluster communication. 

Your client will have to change their application's port numbers.
