I don't know if version 6.2 will do this because I use version 7.1. I recommend to you to upgrade to version 7.x any way. For not so experienced persons the version 7.x web interface is a lot better to understand.
To limit the bandwidth for specific traffic you must use a policy class.
First define a access-list with permit statements to include the traffic that you want to limit.
Then use an otherwise empty class-map with just this access-list
Finally create a policy map that will police (limit) the bandwidth for this class-map.
In this example mebo is a local machine that will talk to a machine named mserver. I have limited the traffic from mebo to mserver to 256kbit.
access-list aclpm_mebo extended permit ip host mebo host mserver
class-map class_mebo
match access-list aclpm_mebo
!
policy-map policy_outbound
class class_mebo
police 256000 150000
Please notice the line police 256000 150000, where 256000 is bit per second, 150000 is burst rate in byte per second. I don't know why Cisco puts byte per second and bit per second in one line. This access-list will be used only for this class-map, it is not used at any interface.
You will need thee policy maps to achieve what you want.
