H3C交换机端口限速技巧全攻略

H3C华为交换机端口限速有以下方法：

line-rate(lr)

speed

traffic-limit

qos car

二层较为准确（如：lr,speed),三层不准确（如：traffic-linit,qos car)

lr :

E050：(可信度100%)

[Quidway-Ethernet0/1]line-rate ?

INTEGER<1-100> Target rate(Mbps

S5500：(可信度100%)

[S5500-GigabitEthernet1/0/1]qos lr outbound cir ?

INTEGER<64-1000000> Committed Information Rate(kbps), it must be a multIPle of 64

speed : (可信度100%)

[S5500-GigabitEthernet1/0/1]speed ?

10 Specify speed of current port 10Mb/s

100 Specify speed of current port 100Mb/s

1000 Specify speed of current port 1000Mb/s

auto Enable port’s speed negotiation automatically

traffic-limit : (可信度50%,当设定50M时，带宽为7M左右；当设定10M时，带宽为1M左右)

[Quidway E050-Ethernet0/1]traffic-limit inbound ip-group 2000 ?

INTEGER<1-100> Target rate(Mbps)

link-group Apply the link-based acl

rule Specify the ID of acl rule

qos car :(s5500)(可信度50%,当设定9.6M时，带宽为5M左右)
