rte_mtr_params(3) DPDK rte_mtr_params(3) NAME rte_mtr_params SYNOPSIS #include <rte_mtr.h> Data Fields uint32_t meter_profile_id int use_prev_mtr_color enum rte_color * dscp_table enum rte_color * vlan_table int meter_enable uint64_t stats_mask uint32_t meter_policy_id enum rte_color default_input_color Detailed Description Parameters for each traffic metering & policing object See also enum rte_mtr_stats_type Definition at line 264 of file rte_mtr.h. Field Documentation uint32_t meter_profile_id Meter profile ID. See also rte_mtr_meter_profile_add() Definition at line 266 of file rte_mtr.h. int use_prev_mtr_color Meter input color in case of MTR object chaining. When non-zero: if a pre- vious MTR object is enabled in the same flow, then the color determined by the latest MTR object in the same flow is used as the input color by the current MTR object, otherwise the current MTR object uses the dscp_table to determine the input color. When zero: the color determined by any previous MTR object in same flow is ignored by the current MTR object, which uses the dscp_table to determine the input color. Definition at line 277 of file rte_mtr.h. enum rte_color* dscp_table Meter input color based on IP DSCP protocol field. Valid when input_color_proto_mask set to any of the following RTE_MTR_COLOR_IN_PROTO_OUTER_IP, RTE_MTR_COLOR_IN_PROTO_INNER_IP When non-NULL: it points to a pre-allocated and pre-populated table with exactly 64 elements providing the input color for each value of the IPv4/IPv6 Differentiated Services Code Point (DSCP) input packet field. When NULL: it is equivalent to setting this parameter to an all-green popu- lated table (i.e. table with all the 64 elements set to green color). The color blind mode is configured by setting use_prev_mtr_color to 0 and dscp_table to either NULL or to an all-green populated table. When use_prev_mtr_color is non-zero value or when dscp_table contains at least one yellow or red color element, then the color aware mode is config- ured.

Valid when input_color_proto_mask set to any of the following RTE_MTR_COLOR_IN_PROTO_OUTER_VLAN, RTE_MTR_COLOR_IN_PROTO_INNER_VLAN When non-NULL: it points to a pre-allocated and pre-populated table with exactly 16 elements providing the input color for each value of the DEI(1bit), PCP(3 bits) input packet field. When NULL: it is equivalent to setting this parameter to an all-green popu- lated table (i.e. table with all the 16 elements set to green color). The color blind mode is configured by setting use_prev_mtr_color to 0 and vlan_table to either NULL or to an all-green populated table. When use_prev_mtr_color is non-zero value or when vlan_table contains at least one yellow or red color element, then the color aware mode is config- ured.

Ignored when the meter profile indicated by meter_pro- file_id is set to NONE. See also rte_mtr_meter_disable() Definition at line 336 of file rte_mtr.h. uint64_t stats_mask Set of stats counters to be enabled. See also enum rte_mtr_stats_type Definition at line 341 of file rte_mtr.h. uint32_t meter_policy_id Meter policy ID. See also rte_mtr_meter_policy_add() Definition at line 344 of file rte_mtr.h. enum rte_color default_input_color Input color to be set for the input packet when none of the enabled input color methods is applicable to the input packet. Ignored when this when in- put_color_proto_mask set to zero. Definition at line 350 of file rte_mtr.h. Author Generated automatically by Doxygen for DPDK from the source code.
