Thanks Jim, The line cards are 6700 series only. It seems (i will test it) that wrr commands can only be associated with COS marking not DSCP nor EXP. May be Priority Queuing is not supported for MPLS traffic on 6700 modules ? On Wed, Nov 17, 2010 at 3:36 PM, Rampley Jr, Jim F < jim.rampley@chartercom.com> wrote:

This depends on which line cards you have in your chassis. This configuration below won't work on 6700 series line cards. You have to use the wrr commands. I didn't test it, but MQC configuration below should work on ES series line cards.

I would to translate following 7200 QoS configuration to Catalyst 6500:

class-map match-any PQ match dscp ef match mpls experimental topmost 5

policy-map QOS-PE-OUT class PQ priority percent 33 class class-default

AFAIK we need extra command on 6500 to enable Priority Queuing at the interface level but my problem is that interface priority command are only COS based not DSCP nor EXP. I may be wrong.

I would appreciate any 6500 QoS help.

Thanks in advance

As it relates directly to QoS on 6700 series cards, yes those blades do COS based QoS. So if you want to put voice traffic in a priority queue you would do something like this: ! map COS 5 to the priority queue, assuming you want COS 5 in the priority queue priority-queue cos-map 1 5 ! Set the queue limit to the size you want priority-queue queue-limit 10 Jim From: Chris Evans [mailto:chrisccnpspam2@gmail.com] Sent: Wednesday, November 17, 2010 10:59 AM To: Manu Chao Cc: NANOG list; Rampley Jr, Jim F Subject: Re: Cisco 6500 QoS Priority Queuing (DSCP & EXP based) These are lan modules. They have fixed queues that you map traffic into. Research lan qos methods and it should make sense.
