Hi,


I am not experienced at all with Huawei switches.

I am facing some problems to establish a stack between two CE5855 and dac cables in 40 GE interfaces.

Following instructions I configure stack parameters in both members and when I add ports to stack-port I have some errors:


[*SWitch-A-Stack-Port1/1]port member-group interface 40GE 1/0/1 to 1/0/2

Error: 40GE1/0/1 and 40GE1/0/2 can not join the same Stack-Port


Both switches are running same version:

CE5855EI V200R005C10SPC800


But, according to the configuration guide, it should be ok.


Any idea?


Thanks in advance

Hello@ TFM,

The wissal documentation above also mentioned. To use 10GE optical ports of a CE5855-48T4S2Q-EI switch for stack connection, you can only add 10GE1/0/1 to 10GE1/0/2 and 10GE ports split from 40GE1/0/2 (40GE1/0/2:1 to 40GE1/0/2:4) to the same logical stack port or add 10GE1/0/3 to 10GE1/0/4 and 10GE ports split from 40GE1/0/1 (40GE1/0/1:1 to 40GE1/0/1:4) to the same logical stack port. To use 40GE optical ports of a CE5855-48T4S2Q-EI switch for stack connection, do not add 40GE1/0/1 and 40GE1/0/2 to the same logical stack port. Please follow the operation document for the stack configuration.

Many thanks for your help.

It is working now, creating different logical stack ports.
