QoS 6500 Sup720 3B - Rate limit 100Mb down to 30Mb

Hi

I have a 6500 with Sup 720 3B and would like to limit a port down from 100Mb to 30Mb.

The router is a perimeter device with a northbound ISP interface of 100Mb and a south bound internal interface of 100Mb.

I want the south bound interface to run at 30Mb rather than the full 100.

I have been digging around and the only well documented solution looks like policing, I would prefer to shape.

I have seen suggestions of srr-queue but this is not supported on this device.

Can anyone offer suggestions please?

Thanks

A

Shaping isn't generally supported on most 6500 line cards.  (One of the few exceptions is the FlexWAN cards; don't recall if they support Ethernet.)

If you really want to shape, depending on how complex your shaping need are, your least expensive option might be to place a small (8 port) 2960/3560 series switch, in-line.  They support basic port "shaping".

HiThanks for the response. I

Hi

Thanks for the response. I have found an alternate work around which is to use Aggregate Policing with burst and extended burst rate... not ideal, but testing tomorrow and should hopefully do the trick..... I have shared it below.

! note that the policy on the card i am using can be applied inbound only... not sure if there are other methods or bi-dir cards?
