Command Usage
• The precedence for priority mapping is IP Port, IP Precedence or IP
DSCP, and default switchport priority.
• IP Precedence values are mapped to default Class of Service values on
a one-to-one basis according to recommendations in the IEEE 802.1p
standard, and then subsequently mapped to the four hardware priority
queues.
• This command sets the IP Precedence for all interfaces.

value 0:
