Re: [c-nsp] Any one ever worked on Cisco 6500 QOS specifically 6503 or 6524(help) needed
You have “mls qos trust cos”, which would maintain the L2 COS parameter, but set the DSCP values to 0. You’ll either need to map COS to DSCP values or trust dscp values. ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
Re: [c-nsp] Any one ever worked on Cisco 6500 QOS specifically 6503 or 6524(help) needed
Hi Andrew, Matthew & others, I would like to thanks for your guidance & help.I checked that PFC qos document but my config still not working. I am still having issue on 6503 Cisco Switch. *" Can any one give me any sample of 6524 or 6503 QOS working configuration, i would be really thankful "* As i have mentioned in my 1st post of configuration of 6503. I am unable to match mpls exp 5 packet on 6503. My qos configuration on PE1(2811 router) is working perfectly. I am unable to classify mpls ex5 or mpls exp3 on 6503 switch. Am i missing something on configuration?

Re: [c-nsp] Any one ever worked on Cisco 6500 QOS specifically 6503 or 6524(help) needed
Hi Ashan, Read the link that Matthew sent you (see below). You will need to understand this to make any changes safely on this platform. You can do QOS on the 6500s - but as the others have said, it is very different to the routers. Each line card is slightly different, so when you have read up on how to do what you want to do - check that it is supported on your chosen line cards! WARNING: Enabling QOS on the 6500s will reconfigure/ split up the buffers on your line cards - so make sure you are aware of this before you start.

Re: [c-nsp] Any one ever worked on Cisco 6500 QOS specifically 6503 or 6524(help) needed
I would like to say thanks both of you who replied. Is there any other solution. Can i use any other IOS. Can i use hierarchical QOS?. What is the solution of this issue. Because we are using majority 6503 Cisco switches on our border in our company. i can not change these switches, not in my control. can i use queuing on 6503 interfaces. Is there any way to prioritize voip traffic on these switches if MQC is not possible can i do priority Queuing for voip traffic? I would be thankful & appreciated on solutions & replies.

6748 is a switch based line card. It has limited qos features supported as compared to a routed platform such as ISR router.

[c-nsp] Any one ever worked on Cisco 6500 QOS specifically 6503 or 6524(help) needed
Hi All, I am having issue specifically doing QOS configuration on 6503 or 6524 or 6509 switches. I am unable to match any EF(voice) traffic for eompls(vlan based) on 6503 cisco switch. If i use any other router as 2811 or 2821 my QOS configuration works perfect but if i put 6503 as PE2 it does not work.i am using vlan based eompls. Below is the scenario & configuration which i am having issue. CE1(2821 router)(dot1Q)->PE1(2821 router)--->P(6524 switch)>PE2(6503 switch)--->(dot1Q)(2821 switch)CE2. On CE1 i can match ip-precedence 5 traffic and mark that traffic to cos5 on outbound port.On PE1 i can match cos5 packet and mark with mpls exp top5 on inbound port, on outbound port i can match mpls exp 5. On PE2(6503) i am unable to match that mpls exp5 packet on inbound port. none of the configuration worked on 6500 series switches with mls qos, ,mls qos trust dscp,mls qos trust cos etc. Although i can match cos5 traffic on CE2 on inbound interface.i can not match mpls exp 5 traffic on 6503 and all i can see traffic as default-class on 6503 switch. I tried many things and many configurations on 6503 but nothing worked.If i put 2821 router as PE2 instead of 6503 my qos configuration works. but why if i put 6503 my same qos configuration does not work? ---match means=classification or classify Can anyone tell me how qos works on 6500 series switches or where i am having issue in my scenario. i am using this ios on 6503: s72033-advipservicesk9_wan-mz.122-33.SXI3.bin. below r my questions for 6503 qos: 1.do i need to use some other map tables,am i using correct map tables on 6503 as cos-dscp,dscp-cos,exp-dscp etc. 2.any other configuration of qos needed on 6503? 3.i am unable to match anything on outbound port of 6503. 4.on 6503 i am using sup720 and PFC3BXL.any specific configuration needed for PFC3bxl. 5. 6503 not allowing me to match qos-group on inbound interface, not allowing me to set cos5 on outbound interface. not allowing me to set cos5 as an inbound interface.
