4000 Router Series ACL and QoS Configuration Guide

Configuration example

Network requirements

As shown in Figure 21, redirect the traffic that GigabitEthernet 1/1 receives from the network segments

2.2.2.0/24 and 3.3.3.0/24 to GigabitEthernet 1/2 and GigabitEthernet 1/3, respectively.

Configuration procedure

# Create basic ACL 2000, and configure a rule to match packets from the network segment 2.2.2.0/24.

<RouterA> system-view

[RouterA] acl number 2000

[RouterA-acl-basic-2000] rule permit source 2.2.2.0 0.0.0.255

[RouterA-acl-basic-2000] quit

# Create basic ACL 2001, and configure a rule to match packets from the network segment 3.3.3.0/24.

[RouterA] acl number 2001

[RouterA-acl-basic-2001] rule permit source 3.3.3.0 0.0.0.255

[RouterA-acl-basic-2001] quit

# Create a traffic class named classifier_1, and use ACL 2000 as the match criterion in the traffic class.

[RouterA] traffic classifier classifier_1

[RouterA-classifier-classifier_1] if-match acl 2000

[RouterA-classifier-classifier_1] quit

# Create a traffic class named classifier_2, and use ACL 2001 as the match criterion in the traffic class.

[RouterA] traffic classifier classifier_2

[RouterA-classifier-classifier_2] if-match acl 2001

[RouterA-classifier-classifier_2] quit

# Create a traffic behavior named behavior_1, and configure the action of redirecting traffic to

GigabitEthernet 1/2.

[RouterA] traffic behavior behavior_1

[RouterA-behavior-behavior_1] redirect interface GigabitEthernet 1/2

[RouterA-behavior-behavior_1] quit

# Create a traffic behavior named behavior_2, and configure the action of redirecting traffic to

GigabitEthernet 1/3.

[RouterA] traffic behavior behavior_2

[RouterA-behavior-behavior_2] redirect interface GigabitEthernet 1/3

[RouterA-behavior-behavior_2] quit

# Create a QoS policy named policy, and associate the traffic classes classifier_1 and classifier_2 with

the traffic behaviors behavior_1 and behavior_2, respectively.
