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.
