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).
do show
Executes all
show commands while in Configuration mode.

Syntax Description
do show
Usage Guidelines
Use this command to
run all Exec mode
show commands while in Configuration mode. It
is not necessary to exit the Config mode to run a
show command.
The pipe character
| is only
available if the command is valid in the Exec mode.
 Caution |
There are some
Exec mode
show commands which are too resource
intensive to run from Config mode. These include:
do show support
collection,
do show support
details,
do show support
record and
do show support
summary. If there is a restriction on a specific
show command, the following error message
is displayed:
Failure: Cannot execute 'do show support' command from Config mode.
|
end
Exits the current configuration mode and returns to the Exec mode.

Usage Guidelines
Use this command to return to the Exec mode.
exit
Exits the current mode and returns to the parent configuration mode.

Entering the above command sequence results in the following prompt:

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