Set up a classification rule according to ACL, VLAN ID, IP Precedence or DSCP to classify the

data stream. Different classes of data streams will be processed with different policies.

3. Configure a policy map.

After data steam classification, a policy map can be created to associate with the class map

created earlier and enter class mode. Then different policies (such as bandwidth limit, priority

degrading, assigning new DSCP value) can be applied to different data streams. You can also

define a policy set that can be used in a policy map by several classes.

4. Apply QoS to the ports

Configures the trust mode for ports or bind policies to ports. A policy will only take effect on a

port when it is bound to that port.

5. Configure queue out method and weight

Configures queue out to PQ or WRR, sets the proportion of the 8 egress queues bandwidth and

mapping from internal priority to egress queue.

6. Configure QoS mapping

Configures the mapping from CoS to DSCP, DSCP to CoS, DSCP to DSCP mutation, IP

precedence to DSCP, and policed DSCP.

1. Enable QoS

Command Explanation

Global Mode

mls qos

no mls qos

Enables/disables QoS function.

2. Configure class map

Command Explanation

Global Mode

class-map <class-map-name>

no class-map <class-map-name>

Creates a class map and enters class map

mode; the “no class-map

<class-map-name>” command deletes

the specified class map.

match {access-group <acl-index-or-name> | ip

dscp <dscp-list>| ip precedence

<ip-precedence-list>| vlan <vlan-list>}

no match {access-group | ip dscp | ip

precedence | vlan }

Sets matching criterion (classify data

stream by ACL, DSCP, VLAN or priority,

etc) for the class map; the “no match

{access-group | ip dscp | ip precedence |

vlan}” command deletes specified

matching criterion.
