I am trying to do an egress rate-limit on a 6500 Sup720/PFC3B 10/100 port. Everything I read seems to say it supports egress rate-limiting, but it will never let me bind a policy-map "output" on my interface. I am trying to rate-limit a 100Mbps interface to 10mbps/10Mbps. This is what I have so far. My ingress rate-limit seems to be working just fine. Any help would be greatly appreciated! Much Thanks....ahead of time.

Use.
Generic Traffic Shaping or Rate-limit (CAR)on the interface.
Best would be Generic Traffic Shaping.

CAR

I apprecaite your help, but both GTS and CAR in the two links you sent me are for a layer3 interface.
I need to do egress rate limiting on a layer2 interface. Both the "rate-limit" and "traffic-shaping" commands are only allowed on a layer3 interface.
Do you happen to know somthing for layer2?
Thanks!

Hi,
Sorry.
On layer 2 you can implement srr-queue
Its works a bit different:
Switch(config-if)# srr-queue bandwidth ?
limit -Configure bandwidth-limit for this interface
shape -Configure shaping on transmit queues
share -Configure shared bandwidth
below is the link for cisco 2690 switch.

Pravin,
I actually use the "srr-queue bandwidth" command currently on some of my 3560G switch's and it works fine, but my 6500's seem to only support Weighted Round-Robin queuing?
I an running ver 12.2(18)SXF8 on Sup720-3B's?
Do you know if I can do anything with egress rate-limiting and the "wrr-queue bandwidth" command, because it won't let me set a limit and seems to only let me specify a weight to queue ratio.
Thanks for your help!
