C H A P T E R 8 Quality of Service (QoS)
To enable the replacement of DiffServ code points you must enable
both 802.1p replacement and DiffServ replacement using the
following commands:
enable dot1p replacement ports [<portlist> | all]
enable diffserv replacement ports [<portlist> |
all]
The default 802.1p priority value to code point mapping is
described in Table 37.

You can change the 802.1p priority to DiffServ code point mapping
to any code point value using the following command:
config diffserv replacement priority <vpri>
code_point <code_point> ports [<portlist> | all]
By doing so, the hardware queue used to transmit a packet
determines the DiffServ value replaced in the IP packet.
To verify the DiffServ configuration, use the command:
show ports <portlist> info {detail}
