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.

Example

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)#
