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 use in a policy map by several classes.

Apply QoS to the ports or the VLAN interfaces

Configure 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.

The policy may be bound to the specific VLAN.

It is not recommended to synchronously use policy map on VLAN and its port.

Configure queue management algorithm

Configure queue management algorithm, such as sp,wrr,wdrr,sp+wrr,sp+wdrr, and so on.

1. Configure class map.

Command

Explanation

Global Mode

class-map <class-map-name>

no class-map <class-map-name>

Create a class map and enter 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>| ipv6 access-group <acl-

index-or-name> | ipv6 dscp <dscp-list>| ipv6

flowlabel <flowlabel-list>|vlan <vlan-list> | cos

<cos-list> | c-vlan <vlan-list>}

no match {access-group | ip dscp | ip

precedence | ipv6 access-group | ipv6 dscp |

ipv6 flowlabel | vlan | cos | c-vlan}

Set matching criterion (classify data

stream by ACL, CoS, VLAN ID, IPv4

Precedent, IPv6 FL or DSCP, etc) for the

class map; the no command deletes

specified matching criterion.

2. Configure a policy map
