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.
