But, that would be the ip address of secondary node. How do I give ip address of primary node for specific Ethernet port ? What I am looking for is when primary sends the logs it should send over this dedicated link. Does configuring sqlhosts on secondary node as suggested above takes care of it ?

Otherwise, you can simply create a distinct listener thread with it's own TCP port.
