Ring Numbers
Forwarding frames between CRFs in SRB mode is only possible if the CRFs know 
their ring numbers. If you are running the switch in an environment without other 
bridges/switches, auto-configuration of ring numbers is not possible. In this case, 
you have to configure the ring numbers manually.
