qos command confusion

[jalaluldeen]

Hi everyone;

i was going through some of the configs on our service provider managed cpe device.

policy-map CUSTOMER_POLICY_IN

class class-default

police cir <EF policing rate in bps>bc <Policing Burst Parameters, in Bytes>

conform-action set-dscp-transmit ef

conform-action set-qos-transmit 6

exceed-action drop

I am not able to understand the command marked as red. Can some body please help me understand as to what is happening there. What does 6 mean in this command?

regards

Hello Jalal,

set-qos-transmit

Sets the QoS group internal label to specified value and transmits the

packet. This action can be used only in input policies and is available

only when the packet conforms to the parameters

Hi Jalal,

Packet Marking could be done Through IP Precedence, QoS Group, and DSCP Value Setting

A user can assign up to 8 IP precedence markings, 64 IP DSCP markings, and 100 QoS group markings.

Associating a packet with a QoS group allows users to associate a group ID with a packet. The group ID can be used to classify packets into QoS groups based on prefix, autonomous system, and community string.

Use QoS packet marking to assign packets to a QoS group. The router uses the QoS group to determine how to prioritize packets for transmission.

The following example sets the QoS group to 1 for all packets that match the class 1 class map. These packets are then rate limited based on the QoS group ID.

Router(config)# policy-map policy1
Router(config-pmap)# class class1
Router(config-pmap-c)# set qos-group 1

To display QoS group information, use the show ip cef command.

This command you marked in red (set-qos-transmit ) is used to set the QoS group before sending a packet just like set qos-group , but specifically in a control statement.

Regards.
