Usage Guidelines You can only use this form of the set cos (policy map type queuing) command for ingress default type
queuing classes. For a table of system-defined queuing class maps, see
The CoS values that you set by using the set cos command apply to all packets that ingress the specified
Note
interfaces (not just to the class-default packets that ingress the interfaces).
If you set the CoS value, the device modifies the value before ingress queuing and scheduling so that the
CoS-modified packets are classified differently.
This command does not require a license.
