Example The following command enables DiffServ examination on selected ports: enable diffserv examination ports 1:1,5:5,6:2 enable diffserv replacement ports enable diffserv replacement ports [ | all] Description Enables the DiffServ code point to be overwritten in IP packets transmitted by the switch. 540 | Chapter 14.
