Interface Configuration (Ethernet, Port Channel)

Command Usage

•The precedence for priority mapping is IP Port, IP Precedence or 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.

Example

The following example shows how to map IP DSCP value 1 to CoS value 0:

Console(config)#interface ethernet 1/5

Console(config-if)#map ip dscp 1 cos 0

Console(config-if)#

show map ip port

Use this command to show the IP port priority map.

Syntax

show map ip port [interface]

interface

•ethernet unit/port

-unit - This is device 1.

-port - Port number.

•port-channel channel-id(Range: 1-4)
