different vendor's ether-channel technology

 

Different vendors ether-channel tech：

Cisco call it	Port-channel
Huawei call it	e-trunk
H3c call it	Bridge-aggregation
什么是链路聚合	简而言之就是这个功能可以让sw在逻辑上将多条物理线缆视为一条线缆！
为什么需要	2个sw如果用一根线连，它可以工作ok 如果你需要怎加2个sw之间的通信带宽，你一般会增加多条网线 这时就需要链路聚合，因为没有链路聚合交换机的生成树会block掉一些端口，导致增加的网线无效
How:
Topology
Cisco	Layer2 ======== interface range FastEthernet0/1-2 switchport trunk encapsulation dot1q switchport mode trunk channel-group 1 mode active  //there is five mode you need to learn about //upon above command sw will auto gen  a port-channel ineterface   Layer3========== interface range FastEthernet0/1-2 no switchport channel-group 1 mode active   interface Port-channel1   //auto generate ip address 1.1.1.2 255.255.255.252 //you can only config ip on port-channel1
Huawei	Layer2============= interface Eth-Trunk1  port link-type trunk  port trunk allow-pass vlan 2 to 4094 trunkport g0/0/1to gi0/0/2  Mode lacp-static //two mode  learn yourself   Layer3==================== int eth-trunk 2 undo portswitch                ip add 10.1.1.1 24             trunkport g0/0/1to gi0/0/2
H3c	Layer2================== interface Bridge-Aggregation1  port link-type trunk  port trunk permit vlan all  Mode dynamic //two mode //该配置将被自动同步到聚合组1内的所有成员端口上   interface GigabitEthernet1/0/1  port link-aggregation group 1   Layer3======================== interface route-aggregation 1  ip address 192.168.1.1 24  quit   interface gigabitethernet 1/0/1  port link-aggregation group 1  quit  interface gigabitethernet 1/0/2  port link-aggregation group 1  quit
Comment	If you going  to build  between two  vendors device  you should mind to choose the right mode
