There is no non-IP traffic, and I did a sh arp/verified the interface IP's in the ACL. I'm going to try it for the sake of it, though if I've got arp entries that aren't showing that might be a bigger problem ;-0
I guess if that fails I will be trying another version over the weekend, and I'll see if that helps.
I would also like rate-limiting to work, because according to
http://www.cisco.com/en/US/products/hw/switches/ps646/ps3816/index.html
"For the first time, customers can deploy network-wide intelligent services, such as advanced quality of service (QoS), **rate-limiting**, Cisco security access control lists, multicast management, and high-performance IP routing-while maintaining the simplicity of traditional LAN switching."
...it should, but I've been unable to find how, and the usual command set doesn't seem to work. Am I missing something here? My immediate thoughts are that perhaps something other than traditional rate-limiting commands is implied?
Thanks,
Tim

Sorry, you don't _have_to use aggregate policer. You could.
Is there any non-ip traffic ? If so, You can create an extra match, and then use an aggregate policer to police it at 3MB. I would also change the IP ACL 102 to match ip any any, just to test it.
mls qos aggregate-policer fas0-01-ipolicer 3000000 8000 exceed-action drop
class-map match-all MATCH-MAC match access-group name MAC-ACL
mac access-list extended MAC-ACL permit any any
policy-map customerA class customerA police aggregate fas0-01-ipolicer class MATCH-MAC police aggregate fas0-01-ipolicer

--------------------------------------------------------------- Well, this is my current config:
Mls qos ! class-map match-all customerA match access-group 102 ! ! policy-map customerA class customerA police 3000000 8000 exceed-action drop ! ! ! interface FastEthernet0/1 description CustomerA - 3MB/s switchport access vlan 4 switchport mode access switchport protected bandwidth 3000 mls qos monitor packets service-policy history service-policy input customerA no cdp enable spanning-tree portfast ! access-list 102 permit ip x.x.x.x 0.0.0.15 any
I made some changes through the day like applying it ingress w/ access-list etc., however, it still spikes up to 5-6Mb. In all of the documentation I've read, I didn't see anything regarding the aggregate as being a necessary configuration step. I guess I'm wondering if it should work without an aggregate policer, because at least with this IOS version and my current configuration it doesn't.
When I do a
Colo-3550#sh mls qos int fa0/1 stat FastEthernet0/1 Ingress dscp: incoming no_change classified policed dropped (in pkts) Others: 38469779 38379716 90063 0 190138 Egress dscp: incoming no_change classified policed dropped (in pkts) Others: 33285081 n/a n/a 0 0
Colo-3550#
I see packets being dropped, but in my monitoring software I still see it spiking up to 5-6Mb.
Thanks,
Tim
