This object is used to specify the type of stacking Interface used for RM communication . Interface can be either an Out of Band port (or) an Inband Ethernet port. This will be specified in issnvram.txt. If an Out of Band port is used,RM Interface should be specified in issnvram.txt . RM Heartbeat and synchronization messages will be transmitted as IP packets. Native Linux TCP/IP stack is used to achieve Transport protocol functionality. If an Inband Ethernet port is used, RM Stack Interface will be specified in Nodeid file . RM Heartbeat messages will be transmitted as Ethernet packets and synchronization messages will be transmitted as IP packets .Supermicro TCP/IP stack is used to achieve Transport protocol functionality.IP Address and the subnet Mask to be used for this TCP/IP communication will be specified in NodeId file. Configuring this object will result in updation to issnvram.txt file. The configured value will take effect in ISS on next reboot.
