I am configured ifenslave LACP on my Debian 8.5. Two ports connected to a Cisco SLM2024 switch. If I disconnect 1 link, everything is ok, the another link working. But when I reconnect the 1st link, I can't ping the server, the network does not work. When I give ifdown bond0 and ifup bond0, the network working again. It is normal? If not, what is the solution?
