Policer_Flow_Mode_Table_{5..6}
Description: This table per-flow mode settings.
Table 273. Policer_Flow_Mode_Table_{5..6} Register Parameters
Table 274. Policer_Flow_Mode_Table_{5..6} Field Parameters
This register provides an assortment of flow-specific mode settings. For the channelized packet_processor
modules (numbers 0 through 4), the eighty policer mode sets are allocated eight per channel. Policers 0 through 7
are allocated to channel 0, policers 8 through 15 to channel 1, etc.
For the nonchannelized packet_processor modules (numbers 5 and 6), all eighty policer mode sets are allo-
cated to the eighty policers of the single channel.

This bit enables the discarding of packets that are out of
profile. A packet is out of profile if its contribution to a
flow’s short-term average bandwidth causes that aver-
age to exceed the flow’s user-defined limit.
This bit enables the discarding of packets that are out of
profile while the switch is congested. The switch is con-
sidered congested when the number of available packet
buffer, packet queue, or packet descriptor resources
falls below user-defined thresholds.
This bit enables the demotion of packets that are out of
profile. When a packet is demoted, it is transmitted at a
lower-priority level.
