firewall ports from 7-Mode to Cluster ONTAP snapmirror

I'm trying to figure out the firewall ports to be opened up to snapmirror data from a 7 Mode filer to a Cluster mode filer.

I couldn't find any documentation about this configuration.I wouldn't be the first to run into this. So I'm surprised i couldn't find much information on this.

From C-Mode ONTAP documentation:

Cluster ONTAP uses  port 11104 to manage intercluster communication sessions and port 11105 to transfer data.

From 7-Mode documentation:

SnapMirror source binds on port 10566. The destination storage system contacts the SnapMirror source storage system at port 10566 using any of the available ports assigned by the system. The firewall must allow requests to this port of the SnapMirror source storage system.

Over what ports does  the  Intercluster-LIF on C-Mode cluster nodes  communicate with a 7 Mode filer to snapmirror the data.

Is there a definitive list of ports to be opened up for snapmirroring from 7-mode to C-DOT filers?

TIA
