fsErpsRingProtectionType

This object specifies the type of protection being provided by this
ring instance. The following two protection switching types are
possible:
     portBased - Port Based Protection 
                 This ring applies the protection switching mechanism
                 for all traffic that pass through its ring ports.
                 Hence when ERP control process decides to block or
                 unblock a ring port, all data traffic that passes 
                 through that port gets affected.
     serviceBased - Service Based Protection.
                 This ring applies the protection switching mechanism
                 only for the set of vlans mapped to this ring instance.
                 Hence when ERP control process decides to block or
                 unblock a ring port, only the data traffic of the vlans
                 that are mapped to this ring instance and that passes 
                 through that port gets affected.
              
All ring nodes in a single ring instance must be configured with the
same protection type.
              
In a single virtual context one ring can run in port based protection
mode and another ring can run in service based protection mode. 
              
It is not recommended to configure a port as ring port in a port based
ring instance as well as in a service based  ring instance.
              
It is not recommended to configure a port as ring port in multiple port 
based ring instance.
              
The ring protection type can be modified only when the row status of 
the ring entry in not in service.
