Priority Commands

map ip precedence (Interface Configuration)

This command sets IP precedence priority (i.e., IP Type of Service priority). Use the no form to restore the default table.

Syntax

map ip precedence ip-precedence-value cos cos-value no map ip precedence

precedence-value- 3-bit precedence value. (Range: 0-7)

cos-value- Class-of-Service value (Range: 0-7)

Default Setting

The list below shows the default priority mapping.

Command Mode

Interface Configuration (Ethernet, Port Channel)

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 eight 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)#

map ip dscp (Global Configuration)

This command enables IP DSCP mapping (i.e., Differentiated Services Code Point mapping). Use the no form to disable IP DSCP mapping.

Syntax

[no] map ip dscp

Default Setting

Disabled

Command Mode

Global Configuration

4-153
