Hi ShuiCheng, I so glad to receive your email again. I solve my trouble by using eth2 instead of eth1000 and having a try with 3.0 Release,instead of 1.0 Relelase. Lantern wish you happiness,good health!

For your environment, with “host-port-list”, there are eth0 ~ eth3, no eth1000. So you should use eth2/eth3, instead of eth1000 as data interface.
