+
+.PP
+.I "NEWMODE"
+- specifies the RDMA subsystem mode. Either exclusive or shared.
+When user wants to assign dedicated RDMA device to a particular
+network namespace, exclusive mode should be set before creating
+any network namespace. If there are active network namespaces and if
+one or more RDMA devices exist, changing mode from shared to
+exclusive returns error code EBUSY.
+
+When RDMA subsystem is in shared mode, RDMA device is accessible in
+all network namespace. When RDMA device isolation among multiple
+network namespaces is not needed, shared mode can be used.
+
+It is preferred to not change the subsystem mode when there is active
+RDMA traffic running, even though it is supported.
+
+.SH "EXAMPLES"
+.PP
+rdma system show

+.PP
+rdma system set netns exclusive
+.RS 4
+Sets the RDMA subsystem in network namespace exclusive mode. In this mode RDMA devices
+are visible only in single network namespace.
+.RE
+.PP
+rdma system set netns shared
+.RS 4
+Sets the RDMA subsystem in network namespace shared mode. In this mode RDMA devices
+are shared among network namespaces.
