A ligação Debian LACP não está funcionando bem?

Question

Eu estou configurado ifenslave LACP no meu Debian 8.5. Duas portas conectadas a um switch Cisco SLM2024. Se eu desconectar 1 link, tudo está ok, o outro link funcionando. Mas quando eu reconectar o primeiro link, não consigo pingar o servidor, a rede não funciona. Quando eu dou ifdown bond0 e ifup bond0 , a rede está funcionando novamente. É normal? Se não, qual é a solução?
