My question is how to configure QoS on 3750/6509/7206  ?

A: First you need to find in addition to all applications other than voice, and network design for a QOS protocol. Voices are of course a top priority. And you can configure the switches on the agreement. You can follow the steps below to operate.

Step One: Create a directory to connect to the traffic classification applications using MAC address or port number used for sorting.

Use the command:

access-list (access-list-number) permit (protocol) (source) (source-wildcard) (port) (destination) (destination-wildcard) (port)

Step two: create a category map

Use the command:

class-map class-map-name

The third step: the definition of a matching condition:

Use the command:

Match access-group (the number given to access-list in step 2)

Step four: create a map to define the protocol to the management protocol was previously created by the identification of categories of traffic.

Use the command:

policy-map (name)

Step five: paste-type

Use the command:

Class (class map name as given in step 2)

Sixth step: the definition of the environment for such.

Use the command:

bandwidth 128

Seventh step: at the application protocol interface on the map.

Use the command:

service policy output (class-name)

I hope the above steps to help you.
