2.5.2 Rate Policing QoS
This router supports Rate Policing QoS. User can specify a L3/4 criterion and associate it with a maximum token (packet rate or data rate based). If a packet arrives and it matches to a rate policing entry, router decreases entry’s allocated token by one (if pps based) or by packet length in bytes(if bps based). If unfortunately the packet just run out of allocated tokens, then it would be dropped directly or logged to software, depends on the setting of Drop Log field.

|
|
| rate policy, set 0 to both Start Port and End Port. |
| Rate / Unit / |
