华为交换机用流策略根据IP限速

在华为交换机上做基于IP段的流量限速

根据 IP 地址进行限速

对IP地址为192.168.1.10的PC限速，带宽限制为4M。

=============================================

企业网用户的IP为10.0.0.2/24，通过Switch连接Internet。Switch为运营商设备。企业网用户只租用了1Mbps的上行带宽和2Mbps的下行带宽。

配置思路
流量监管功能是通过QoS命令行实现。本案例中，用户采用固定IP，因此可以通过匹配用户IP地址的方法匹配用户流量，并对其做流量监管。

配置步骤

# 配置ACL规则匹配源IP为10.0.0.2的流量
    <H3C> system-view
    [H3C] acl number 3001
    [H3C-acl-adv-3001] rule permit ip source 10.0.0.2 0
    [H3C-acl-adv-3001] quit

# 配置ACL规则匹配目的IP为10.0.0.2的流量
    [H3C] acl number 3002
    [H3C-acl-adv-3002] rule permit ip destination 10.0.0.2 0
   [H3C-acl-adv-3002] quit

# 配置流分类，匹配ACL规则3001，即匹配源IP为10.0.0.2的流量
    [H3C] traffic classifier source_hostA
    [H3C-classifier-source_hostA] if-match acl 3001
    [H3C-classifier-source_hostA] quit

# 配置流分类，匹配ACL规则3002，即匹配目的IP为10.0.0.2的流量
    [H3C] traffic classifier destination_hostA
    [H3C-classifier-destination_hostA] if-match acl 3002
    [H3C-classifier-destination_hostA] quit

# 配置流行为，用于对上行流量进行流量监管，速率为1000kbps
    [H3C] traffic behavior uplink
    [H3C-behavior-uplink] car cir 1000
    [H3C-behavior-uplink] quit

# 配置流行为，用于对下行流量进行流量监管，速率为2000kbps
    [H3C] traffic behavior downlink
    [H3C-behavior-downlink] car cir 2000
    [H3C-behavior-downlink] quit

# 配置QoS策略，用于端口入方向，即用户的上行方向
    [H3C] qos policy uplink
    [H3C-qospolicy-uplink] classifier source_hostA behavior uplink
    [H3C-qospolicy-uplink] quit

# 配置QoS策略，用于端口出方向，即用户的下行方向
    [H3C] qos policy downlink
    [H3C-qospolicy-downlink] classifier destination_hostA behavior downlink
    [H3C-qospolicy-downlink] quit

# 在端口上下发QoS策略，匹配出入方向的流量
    [H3C] interface GigabitEthernet 3/0/1
    [H3C-GigabitEthernet3/0/1] qos apply policy uplink inbound
    [H3C-GigabitEthernet3/0/1] qos apply policy downlink outbound

S系列交换机（S1700除外）和E系列交换机基于IP网段配置限速

是通过ACL和MQC实现的，关键配置如下：

基于源地址

system-view //进入系统视图

[HUAWEI] acl 3000 //创建ACL

[HUAWEI-acl-adv-3000] rule permit ip source 192.168.1.0 0.0.0.255 //通过配置规则（rule）匹配数据流

[HUAWEI-acl-adv-3000] quit

[HUAWEI] traffic classifier c1 //创建流分类

[HUAWEI-classifier-c1] if-match acl 3000 //匹配ACL

[HUAWEI-classifier-c1] quit //退出

[HUAWEI] traffic behavior b1 //创建流行为

[HUAWEI-behavior-b1] car cir 4000 pir 10000 green pass //配置流策略做限速

[HUAWEI-behavior-b1] quit

[HUAWEI] traffic policy p1 //创建流策略

[HUAWEI-trafficpolicy-p1] classifier c1 behavior b1 //匹配流分类和流行为

[HUAWEI-trafficpolicy-p1]quit

[HUAWEI] interface ethernet 0/0/2

[HUAWEI-Ethernet0/0/2] traffic-policy p1 inbound //在接口Eth/0/2(数据流进入设备的接口）入方向上调用流策略p1

[HUAWEI-Ethernet0/0/2] quit

基于目的地址

acl number 3200

rule 5 permit ip destination 192.168.0.0 0.0.255.255

rule 10 permit ip source 192.168.0.0 0.0.255.255

traffic classifier cvpn operator or

if-match acl 3200

traffic behavior bvpn
