QoS L2 Mapping Configuration Mode Commands

The QoS Mapping Mode is used to map internal QoS priority with Class of Service (CoS) values.

Mode

Exec > Global Configuration > QoS L2 Mapping Configuration

configure > qos-l2-mapping

Enter the above command sequence results in the following prompt: 

[local] host_name (config-qos-l2-mapping)#

The commands or keywords/variables that are available are dependent on platform type, product version and installed license(s).


Important

For information on common commands available in this configuration mode, refer to the Common Commands chapter.

internal-priority

Maps internal QoS priority with Class of Service (COS) values

Privilege

Administrator

Mode

Exec > Global Configuration > Qos L2 Mapping Configuration

configure > qos l2-mapping-table { name map_table_name | system-default }

Entering the above command sequence results in the following prompt: 

[local] host_name (config-qos-l2-mapping)#

Syntax

internal-priority cos class_of_service_value color color_value [ 802.1p-value 802.1p_value ] [ mpls-tc mpls_tc_value ] 
default internal-priority cos cos_value color color_value

default

Restores default value assigned for specified parameter.

cos class_of_service_value

Maps to the internal QoS priority/COS.

class_of_service_value must be a Hexadecimal number between 0x0 and 0x7.

color color_value

Controls drop precedence of service to map to.

color_value must be a Hexadecimal number between 0x0 and 0x3.

802.1p-value 802.1p_value

Map to a 802.1p value. This also includes both P-bits and DEI/CFI. DEI is the lsb bit.


Caution

Setting an odd value (DEI/CFI to 1) makes some switches drop packets.

802.1p_value must be a Hexadecimal number between 0x0 and 0xF.

mpls-tc mpls_tc_value

Map to an MPLS traffic class.

mpls_tc_value must be a Hexadecimal number between 0x0 and 0x7.

Usage Guidelines

This command is used to map internal QoS priority with COS values.


Important

The internal-priority CLI command also offers the ability to configure both 802.1p priority and setting of DEI/CFI bit. This flexibility installation will treat the bit as DEI (drop eligibility indicator). However, for installations that treat the bit as CFI (canonical format indicator), this should be set to 0. Otherwise, the packet will be dropped.

Example

This command is used to map internal QoS priority with COS values: 
     internal-priority cos 0x2 color 0x1
