◆
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 eight hardware priority
queues.
◆
This command sets the IP Precedence for all interfaces.

XAMPLE
The following example shows how to map IP precedence value 1 to CoS
value 0:
Console(config)#interface ethernet 1/5
Console(config-if)#map ip precedence 1 cos 0
Console(config-if)#
