6509 rate-limit not supported, service-policy help

Unanswered Question
May 20th, 2008

I am attempting to transfer the following config to a 6509. When I try to use the command it says it is not supported by hardware, use service-policy instead. Could someone help me get started? thanks.

rate-limit input 30720000 15360 30720 conform-action transmit exceed-action drop

rate-limit output 30720000 15360 30720 conform-action transmit exceed-action drop

I have this problem too.

You don't say which version of software you have on your 6500 but assuming a version of 12.2SXF. I'm also assuming a PFC3 on a supervisor 720. If any of this is wrong please come back.

You need to use MQC syntax for this. From Cisco configuration docs

Note: Policers can act on ingress traffic per-port or per-VLAN. With a PFC3, for egress traffic, the policers can act per-VLAN only. So is it enough to police the interface ingress only ?

Anyway attached is a link to the doc mentioned above with an example of how to police traffic coming in on an interface. The link i have posted takes you straight to the example but the chapter is on configuring QOS for 6500.


Have a look and please come back if you have further questions.

Sorry Jon, I'm a bit of a noob with this equipment.

(I sure with that these posts took spaces)

Here is what I have tried so far..

policy-map ISP_Inbound

class 30mb

police 30720000 15360 30720 conform-action transmit

exceed-action drop

policy-map ISP_Outbound

class 30mb

police 30720000 15360 30720 conform-action transmit

exceed-action drop

class-map match-all 30mb

match access-group 105

access-list 105 permit ip any any

int Gi2/7

bandwidth 30000

service-policy input ISP_Inbound

service-policy output ISP_Outbound

No problem. Are you saying that the config you have applied is not working or not ?

FYI - you do have a Supervisor 720 with a PFC3.

Honestly, I'm not entirely sure what the config is supposed to do or how to check if it's working. I can do "show mls qos", "show mls qos ip gi2/7" etc. and see counters increasing. A little background info. A client was experiencing Citrix sessions dropping occasionally during periods of congestion. The ISP added the "rate-limit" config I posted before. They then asked if we could put the same thing on the clients end. When I tried, I received the message saying that the hardware does not support it. I then tried to transfer that config to the 6509 and this is what I came up with.
