Interface Configuration (Ethernet, Port Channel)

Command Usage

• The precedence for priority mapping is IP DSCP, and default switchport

priority.

• DSCP priority values are mapped to default Class of Service values according

to recommendations in the IEEE 802.1p standard, and then subsequently
mapped to the four hardware priority queues.

• This command sets the IP DSCP priority for all interfaces.
