Description This command allows the user to configure the SAP aggregate policer. The rate of the SAP aggregate
policer must be specified by the user. The user can optionally specify the burst size for the SAP
aggregate policer. The aggregate policer monitors the traffic on different FCs and determines the
destination of the packet. The packet is either forwarded to an identified profile or dropped.
The table below provides information about the final disposition of the packet based on the operating
rate of the per FC policer and the per SAP aggregate policer:
Table 17: Final Disposition of the packet based on per FC and per SAP policer or meter.
When the SAP aggregate policer is configured, per FC policer can be only configured in “trtcm2”
mode (RFC 4115).
Note: The meter modes “srtcm” and “trtcm1” are used in the absence of an aggregate meter.
The SAP ingress meter counters increment the packet or octet counts based on the final disposition of
the packet.
If ingress Frame-based accounting is used, the SAP aggregate meter rate accounts for the Ethernet
frame overhead. The system accounts for 12 bytes of IFG and 8 bytes of start delimiter.
The no form of the command removes the aggregate policer from use.
Default no aggregate-meter-rate
