Hi Chris, I too have pondered this same topic and searched quite a bit on it. The way I understand it is the “police rate” command is intended for use with the Control Plane Policing function. This is the only reference to that command that I was able to find while searching the “QoS” section of the Doc CD:
“For Release 12.3(7)T, the CISCO-CLASS-BASED-QOS-MIB was extended to manage control plane QoS policies, and the police rate command was introduced to support traffic policing on the basis of packets per second for control plane traffic” The use of “cir” in the police command for normal class-based policing makes sense when used to setup the dual-rate policer as it allows you to configure the “pir” as well. If anyone has another take on the subject I would be interested. I tend to avoid using the "police rate" command for normal class-based policing functions. ------ Original Message ------ Received: 09:54 AM EDT, 04/17/2014 From: Christopher Lemish <[email protected]> To: "[email protected]" <[email protected]> Subject: [OSL | CCIE_RS] QoS: Police (How to use this command) Can anyone help clarify the police command. Is there a difference in using "police cir percent 20" vs "police rate percent 20" ? Then, is there a difference in using "police <bits/sec>" Does it do the same thing? My assumption is: * police 8000 //Allows you to specify the actual bits per second (in bps) * police cir perc 20 //When/how is this used? * police rate perc 20 //When/how is this used?
