QCN is a form of end-to-end congestion management defined in IEEE 802.1.Qau. The purpose of QCN is

to ensure that congestion is controlled from the sending device to the receiving device in a dynamic

fashion that can deal with changing bottlenecks.

When an IEEE 802.1p priority is assigned as a CNPV globally, the CNPV configuration for all interfaces

will be created with a default value. When a priority is deleted from CNPV, the CNPV configuration for all

interfaces will be deleted.
