DiffServ
DiffServ addresses the clear need for relatively simple and coarse methods of categorizing traffic into
different classes and applying QoS parameters to those classes. DiffServ supports class-based marking.
Cisco Express Forwarding (CEF) mode is required for DiffServ support. To enable CEF, enter the ip cef
command.
Configuration Example
The following example shows a Cisco 1751 router configured with DiffServ:
access-list 102 permit udp host 16.0.0.4 host 15.0.0.5
access-list 103 permit udp host 16.0.0.4 host 13.0.0.5
ip cef
