H3CICG2000網速限制方法
H3C ICG2000的網速限制方法，你知道嗎?下面yjbys小編為大家分享的就是H3C ICG2000的網速限制方法，希望對大家有所幫助!
通過基于網段的CAR規則可以限制整個網段內每臺主機的速率或者是整個網段的速率，也可以對某一IP地址范圍內的每臺主機的速率或者整個網段的速率進行限制。
5.10.1 對整個網段的速率進行限制
[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 對整個網段的每個IP的速率進行限制
[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 對某一IP地址范圍內的速率進行限制
[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 對某一IP地址范圍內每個IP的速率進行限制
[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
漏了單一IP限速。
還有就是限速會帶來負面影響，舉個例子游戲延時過高，必須解決內外網帶寬不均衡的問題，將內網限速值和外網流量整形值設置成一樣!
舉一個例子：網吧帶寬只有8M，內網PC機有200多臺，很可能就是因為有人在下載或者用QQ live等軟件導致內網流量過大，遠遠超過8M。
所以一般情況下面都需要做速率的限制，對每臺PC機都做。我們處理得很多掉線問題，就是因為沒有做限制速度而導致的。通過dis int e1/0看一下內網流量，如果有Overruns，則多半說明內網流量太大，路由器處理不過來了。

AR18-2X在升級到F1707之后，可以實現基于每個IP地址的限速。1863-1最新版本也支持該功能，命令一樣。
網吧中限制內網PC的速率，上傳速度200K，下載速率300K。
