Two CE6800s stacked and connected to Huawei server. After Eth-trunk 17 is configured, Eth-trunk17 is always Down, but 10GE 1/0/17 and 10GE 2/0/17 are UP.
1) i checked the configuration for eth-trunk 17 on switch side it is ok
2) we found that CE switch sends LACP pdu packets in both modes ( LACP static & LACP dynamic ) but can’t receive from other side ( server side )
3) When we run the command mode lacp-dynamic or mode lacp-static, to configure the working mode of the Eth-Trunk, CE can Ping server successful only when the mode is lacp-dynamic.
4)Log in the server and change the Load balancing setting from” Route Based on Originating Port ID” to “Route Based on IP Hash”
5)Login the CE, run command undo mode to change the Eth-trunk mode to“load balancing” (this is default setting on CE)
ping is ok
The eth-trunk mode between CE and servers is highly recommended to be "LACP dynamic "
Change the CE Eth-trunk mode setting and the server“Load balancing”mode.
