SSH Listening only on Mgmt and IB Network Interfaces?

 My Exadata compute nodes (X2-2) currently only has Secure Shell (SSH) listening on the management network interface (eth0) and the Infiniband network interface (bondib0). See below.

I am curious if other customers and/or Oracle have SSH listening on the public (i.e., Client Access) network interface (bondeth0)? What is best practice?
