Here's a sample configuration that I have used with some success.
PC--vlan4---(2/11)cat6k(5/13)---vlan5----INTERNET
PC--vlan4---(2/12)
PC--vlan4---(2/13)
rate-limit combined traffic from PC's on vlan4 to Internet to 3MB.
PortBased
---------
set qos enable
set qos policer aggregate threeMeg rate 3000 burst 32 drop
set qos acl ip toInternet trust-ipprec aggregate threeMeg ip 10.10.10.0
0.0.0.255 8.0.0.0 1.255.255.255

0.0.0.255 12.0.0.0 3.255.255.255

0.0.0.255 128.0.0.0 63.255.255.255
set qos acl ip toInternet trust-ipprec aggregate threeMeg ip 10.10.10.0
0.0.0.255 192.0.0.0 31.255.255.255
set qos acl ip fromInternet trust-ipprec aggregate threeMeg ip any
10.10.10.0 0.255.255.255
commit qos acl toInternet
commit qos acl fromInternet
set qos acl map toInternet 2/11
set qos acl map toInternet 2/12
set qos acl map fromInternet 5/13
OR VLAN Based
-------------
(just diffs here)
set port qos 2/11-12 vlan-based
set qos acl map toInternet 4
(map to 5/13 would stay same).
I haven't had a chance to test this.

Importance: Low
6509 Running IOS, and I think I had the burst rates wrong in my example
below. I want 9MB of burst, therefore 1125000 bytes of burst (not 1250000).
Am I using the correct logic here?
