Does the policer is done over the vlan aggregated traffic or it will be compute over the traffic coming in from individual vlan member port ?
Aggregated but you can deploy Microflow policers:
We have a 6509 aith 8x48 ports. I was thinking putting a service-policy by port to rate limit and mark the trafic.
After 112 ports where the policy are applied, I reached 1022 aggregated policy used (sh platform hardware capacity qos)!! Starting at port 3/17 I have a message saying Counter not installed ... when I do a show policy-map interface
I thought that Vlan-based QOS could help but microflow policer capacity is less so I don't know ?
We ran into that issue on a recent customer deployment. The problem is that each policy applied to a port will use an agg-id and the hardware limit is 1023.
I covered that scenario on this thread http://tinyurl.com/c6j73c
Ok that my problem, so if I do microflow Vlan-Based QOS - I should be able to simulate the port policer without that agg-id problem ??
It seem that Vlan-Based QOS does not use AGG-ID like Port-Based QOS do ?
I have implemented vlan-based QOS putting Microflow policer on vlan.
I am able to remark (dscp) the traffic with the policer command, but I have no statistics from the command sh policy-map interface vlan and
worst then that no packet are being drop !
Have any ideas ?
You are dealing with switches, so you need to use show mls qos ip command for output.
Does this tell you microflow policing is acting ok (check the attach file)?
Note : When I was doing policer without microflow the command sh policy-map interface was giving the statistics !
show mls ip detail will help you on the microflow policing information.

Thanks for all the answers - it is coming good for me
I have activate Netflow to see the stats.
I am using a policer on ip-src-only. From the doc it seem that we can have 64000 flow by policer.
I suppose that the Netflow table size will limit the number total of flows. have you an idea of how the Netflow table can get ?
