华为交换机如何实现共享带宽(MQC & SuperVlan)

原理：

    1:创建单独的vlan，
    2:并将所需要共享带宽主机的交换机连接端口加入该vlan,
    3:对该vlan进行限速
    4:对共享的口子进行traffic policy的应用
    5:将该vlan作为subvlan加入网关vlan(supervlan)

交换机配置如下

#创建一个超级vlan,并将vlan100加入该supervlan
vlan 3501
 description Gateway
 aggregate-vlan
 access-vlan 100
#
vlan 100

#网关配置在supervlan上，（supervlan能合理利用IP地址）
interface Vlanif3501
 ip address 103.59.42.1 255.255.255.128
 ip address 103.59.42.129 255.255.255.128 sub

#创建流分类，应用到vlan100上
traffic classifier vlan100 operator and
 if-match vlan-id 100
traffic classifier all operator and
 if-match any

#创建流行为
traffic behavior P100M

#创建流策略，匹配流行为流分类
