[c-nsp] Rate limiting VLANs on Cisco 6500

[Ed Butler - RapidSwitch]

This is my first post to this list so please be gentle. :)

We've got a Cisco 6500 with Sup720 (version 12.2(18)SXD5) and WS-X6816
modules (and DFC3a daughtercards.) We have 3 VLANs that we want to rate
limit in an incoming direction, eg they can send up to x mbits of content to
us which we will then route onto the web. Additionally, we're using a port
channel to give redundancy.

However, this is causing problems! The config I'm using is this:

=================================
class-map match-any rsall
match protocol ip
!
policy-map rs1
class rsall
police 320000000 10000000 10000000 conform-action transmit exceed-action
drop
!
interface gi4/16.228
encapsulation dot1Q 228
ip address 1.2.3.4 255.255.255.248
no cdp enable
service-policy input rs1
service-policy output rs1
=================================

When applying the service policies to the subinterface I get errors:
=================================
QoS: Cannot have more than one Match protocol filter in class rsall on
GigabitEthernet4/16.228
QoS: policy rs1 actions for class rsall are not supported on
GigabitEthernet4/16.228
QoS: Cannot have more than one Match protocol filter in class rsall on
GigabitEthernet4/16.228
QoS: Cannot have more than one Match protocol filter in class rsall on
GigabitEthernet4/16.228
=================================


Now, am I barking up the wrong tree here? What is the best way of
implementing rate limiting on our configuration? I've tried quite a few
other config examples, but all seem to have failures or errors. Something
I'm concious of is whether the WS-X6816 card actually supports rate limiting
in hardware at all, I've had a look through and can't find a concise spec
sheet for it.

Anyone with experience or suggestions is greatly apprecaited, thanks!
