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.
Note: The sum of CIR of the individual FCs configured under the SAP cannot exceed the PIR rate
configured for the SAP. Though the 7210 SAS software does not block this configuration, it is not
recommended for use.
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 12: Final Disposition of the packet based on per FC and per SAP policer or meter.
Note*: The row number 2 in the above table is not recommended for use. For more informa-
tion on this, see the Note in the “aggregate-meter-rate” description.
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.
