h3c m-lag简单配置案例

#SWA配置
 [SWA]m-lag system-mac a08e-80d2-0100 #相同，建议选主设备为系统MAC
 [SWA]m-lag system-number 1 #主设备为1，备设备为2

 本实验中，SWB的配置与SWA相比较，仅以下不同
 （1）系统编号不同
 （2）Keepalive配置不同，如接口IP和源目IP#SWC配置
 [SWC]int br 100
 [SWC-Bridge-Aggregation100]link mo dy
 [SWC-Bridge-Aggregation100]int rang g1/0/1 g1/0/2#如果HCL模拟器的M-LAG起不来，两边配置以下命令，忽略一致性检查
 #仅实验目的，生产环境需谨慎
 m-lag consistency-check disable#看状态
