Hello, When I test multichannel. I don't know how to verify if it works. I just catch network packages to see if server and client communicate with multiple IP. But from my test, it doesn't. Does any one know how to verify multichannel? Setup: server is samba server in linux upstream. client is linux upstream. smb.conf is: [global] interfaces = eth1, eth2, team0 server multi channel support = yes vfs objects = recycle aio_pthread aio read size = 1 aio write size = 1 [cifs] path=/mnt/cifs writeable=yes Create network team in server and client. eth1 and eth2 work as team slave. Mount with multichannel option(use one of team ip to mount). Then use "dd" to create 1G file. The used time are the same for multichannel and no multichannel. Compare the time for copying 1G file. The result are also the same. By the way, network team running mode is round-robin. Thanks. -- Best regards! XiaoLi Feng 冯小丽
