Usage Guidelines
CoS packet marking is supported only in the Cisco Express Forwarding switching path.
The set cos command should be used by a router if a user wants to mark a packet that is being sent to a
switch. Switches can leverage Layer 2 header information, including a CoS value marking.
The set cos command can be used only in service policies that are attached in the output direction of an
interface. Packets entering an interface cannot be set with a CoS value.
