Thanks, Karthik, The rate that I found in a solution (it was Lab 16, task 6.3) is set to 1000. And apparently it is a minimal option that IOS knows about. It has always been a big confusion for me with Bc and Be values for different scenario. My notes that I compiled a while ago show different values.
For MQC single rate-policing Bc = (CIR/8) * 0.25, Be = (CIR/8) * 0.3 If it is not mentioned than Bc=Be. Alternatively we do CAR rate-limiting Bc=(CIR/8)*1.5, Be=2Bc. I don't think that we have to memorize these calculations at all otherwise it would be crazy. I rely on the task saying something "ensure the burst size is large enough to accommodate normal and excess burst durations of 200 ms and 300 ms at a rate of 128 Kbps" Eugene From: Karthik sagar [mailto:[email protected]] Sent: Monday, July 30, 2012 3:09 AM To: Eugene Pefti Cc: [email protected] Subject: Re: [OSL | CCIE_Security] Police options for rate limiting police <> and police cir <> commands do the same thing. Infact, the IOS adds the cir keyword when I enter police <> commands. police rate <> commands are used for control-plane policing http://www.cisco.com/en/US/partner/docs/ios-xml/ios/qos/command/N_through_P.html#GUID-EBA1A14B-8D5F-4A87-9484-58AFF6C9920C And for MQC single-rate policing, i think the Bc should be (CIR/8)*0.25, Be=Bc Regards, Karthik
