276 / 444 page  Functional Descriptions VMDS-10492 VSC7440 Datasheet Revision 4.2 259 Both port counters and ESDX counters are updated based on pipeline points and actions. For more information, see Rewriter Pipeline Handling, page 254. The ESDX statistics pipeline points can be configured using the PORT_CTRL.INJ_STAT_PIPELINE_PT and PORT_CTRL.XTR_STAT_PIPELINE_PT registers. The following table shows when the counters are updated. 3.26.5.5 Protection Active Using ES0, the rewriter is able to change various indexes based on the value of the IFH.DST.ENCAP.PROT_ACTIVE field in the IFH. • Use the ES0 key field PROT_ACTIVE to change all ES0 actions when protection is active. • The numbers of ES0 keys are limited, so the same key can optionally generate two different indexes based on the value of IFH.DST.ENCAP.PROT_ACTIVE. This is enabled using the ES0 action PROTECTION_SEL. • The ENCAP_ID, ESDX_BASE and OAM_MEP_IDX indexes can be changed. These indexes are used when enabled by PROTECTION_SEL: ENCAP_ID_P, ESDX_BASE_P, and OAM_MEP_IDX_P. 3.26.6 Mapping Tables The rewriter contains two mapping resources (A and B) that can be used to look up the following fields. • TC value in MPLS labels • DSCP value in IP frames 3 Use VID: Index = Classified VID (IFH.VSTAX.TAG.VID), if no tag is pushed Index = VID of outermost pushed tag, if a tag is pushed Index = REW:VMID:RLEG_CTRL.RLEG_EVID (IFH.DST..ERLEG) if L3. The frame color is used to count multicast frames: Color = FRAME.ETH_LINK_LAYER.DMAC (bit 40). The two MSB bits of the VID are ignored. 1,024 counter indexes are available. Table 181 • Egress Statistics Update Counter Is Updated When? Port Pipeline action is not Extract (action different from XTR, XTR_LATE_REW, XTR_UPMEP, and LBK_ASM). Frame is transmitted (abort = 0). Updated for all egress port numbers including virtual device (VD) and extraction CPU port numbers. ESDX The egress port is a physical port. The frame matches the parameters configured in CNT_CTRL.STAT_MODE: For extracted frames (Action: XTR, XTR_UPMEP and LBK_ASM): The egress statics is located in the pipeline point, PORT_CTRL.XTR_STAT_PIPELINE_PT. Frames extracted in or after this point are counted. For injected frames (Action: INJ, INJ_x, LBK_QS): The egress statics is located the pipeline point, PORT_CTRL.INJ_STAT_PIPELINE_PT. Frames injected in or before this point are counted. Frame is transmitted (abort = 0). The pipeline action is different from XTR_LATE_REW. Abort A frame is aborted by REW or OQS (abort = 1). Counting of frames aborted by REW must be enabled by setting CNT_CTRL.STAT_CNT_FRM_ABORT_ENA. Table 180 • ESDX Index Selection (continued) STAT_MODE Description |
