+.SH "DESCRIPTION"
+.SS rdma statistic [object] show - Queries the specified RDMA device for RDMA and driver-specific statistics. Show the default hw counters if object is not specified
+
+.PP
+.I "DEV"
+- specifies counters on this RDMA device to show.
+
+.I "PORT_INDEX"
+- specifies counters on this RDMA port to show.
+
+.I "FILTER_NAME
+- specifies a filter to show only the results matching it.
+
+.SS rdma statistic <object> set - configure counter statistic auto-mode for a specific device/port
+In auto mode all objects belong to one category are bind automatically to a single counter set. The "off" is global for all auto modes together. Not applicable for MR's.
+
+.SS rdma statistic <object> bind - manually bind an object (e.g., a qp) with a counter
+When bound the statistics of this object are available in this counter. Not applicable for MR's.
+
+.SS rdma statistic <object> unbind - manually unbind an object (e.g., a qp) from the counter previously bound
+When unbound the statistics of this object are no longer available in this counter; And if object id is not specified then all objects on this counter will be unbound. Not applicable for MR's.
+
+.I "COUNTER-ID"
+- specifies the id of the counter to be bound.
+If this argument is omitted then a new counter will be allocated.
+
+.SS rdma statistic mode - Display the enabled optional counters for each link.
+
+.SS rdma statistic mode supported - Display the supported optional counters for each link.
+
+.SS rdma statistic set - Enable a set of optional counters for a specific device/port.
+
+.I "OPTIONAL-COUNTERS"
+- specifies the name of the optional counters to enable. Optional counters that are not specified will be disabled. Note that optional counters are driver-specific.
+
+.SS rdma statistic unset - Disable all optional counters for a specific device/port.
