H3C ICG2000的网速限制方法，你知道吗?下面yjbys小编为大家分享的就是H3C ICG2000的网速限制方法，希望对大家有所帮助!
通过基于网段的CAR规则可以限制整个网段内每台主机的速率或者是整个网段的速率，也可以对某一IP地址范围内的每台主机的速率或者整个网段的速率进行限制。
5.10.1 对整个网段的速率进行限制
[H3C]qos carl 1 source-ip-address subnet 192.168.1.1 24
[H3C]interface GigabitEthernet 1/0
[H3C-GigabitEthernet1/0]qos car inbound carl 1 cir 10000000 cbs 10000000 ebs 0 green pass red discard
5.10.2 对整个网段的每个IP的速率进行限制
[H3C]qos carl 1 source-ip-address subnet 192.168.1.1 24 per-address
[H3C]interface GigabitEthernet 1/0
[H3C-GigabitEthernet1/0]qos car inbound carl 1 cir 10000000 cbs 10000000 ebs 0 green pass red discard
5.10.3 对某一IP地址范围内的速率进行限制
[H3C]qos carl 1 source-ip-address range 192.168.1.10 to 192.168.1.20
[H3C]interface GigabitEthernet 1/0
[H3C-GigabitEthernet1/0]qos car inbound carl 1 cir 10000000 cbs 10000000 ebs 0 green pass red discard
5.10.4 对某一IP地址范围内每个IP的速率进行限制
[H3C]qos carl 1 source-ip-address range 192.168.1.10 to 192.168.1.20 per-address
[H3C]interface GigabitEthernet 1/0
[H3C-GigabitEthernet1/0]qos car inbound carl 1 cir 10000000 cbs 10000000 ebs 0 green pass red discard
漏了单一IP限速。
还有就是限速会带来负面影响，举个例子游戏延时过高，必须解决内外网带宽不均衡的问题，将内网限速值和外网流量整形值设置成一样!
举一个例子：网吧带宽只有8M，内网PC机有200多台，很可能就是因为有人在下载或者用QQ live等软件导致内网流量过大，远远超过8M。
所以一般情况下面都需要做速率的限制，对每台PC机都做。我们处理得很多掉线问题，就是因为没有做限制速度而导致的。通过dis int e1/0看一下内网流量，如果有Overruns，则多半说明内网流量太大，路由器处理不过来了。

AR18-2X在升级到F1707之后，可以实现基于每个IP地址的限速。1863-1最新版本也支持该功能，命令一样。
