If the curr_active_slave fails, its hardware address will be taken over by the newly elected Curr_active_slave.in fact, the difference between mod=6 and mod=0: Mod=6, the first eth0 flow accounted for, and then accounted for Eth1,....ethx, and Mod=0, will find 2 mouth flow is very stable, the basic same

There are many ways to modify the IP address of the network adapter, but there are two types in general. One is temporary modification, which will expire after the network service is restarted. The other is Permanent modification, it takes effect only after the network service is restarted. In general, the temporary modification application is in the temporary action, and we can also know through the classification name, in order to deal with the following temporary problems. The Permanent modif
