Policer_Accumulator_Table_{5..6}
Description: This table is used to accumulate packet data rates.
Table 261. Policer_Accumulator_Table_{5..6} Register Parameters
Table 262. Policer_Accumulator_Table_{5..6} Field Parameters
Rx_Packet_Header.packet_length[13:0] is added to the policer_accumulator[17:0] field that cor-
responds to the packet’s policer for each received packet. On regular intervals, policer_delta[7:0] (or
policer_delta[10:0]) is subtracted from policer_accumulator[17:0]. If
policer_accumulator[17:0] exceeds policer_limit[17:12], then the traffic is considered out of profile.
