Hi all,

We want to add 20 ports in an eth-trunk on CE8860-4C-EI. But when adding the 17th port,  the following error message is displayed.

Error: Failed to add the port into the trunk because the members of the trunk reached the upper limit time.

We have created an Eth-Trunk with 20 ports on the CE6870-24S6CQ-EI, but no such error occurs.

Hello,

By default, the CE6870EI and CE6875EI support 512 LAGs and each LAG supports a maximum of 32 member interfaces, other models(include CE8860-4C-EI) support 128 LAGs and each LAG supports a maximum of 16 member interfaces.

If you want to add more interfaces to LAG then you need to reduce device supported LAG by using the assign forward eth-trunk mode 64 command. Then each LAG will support a maximum of 32 member interfaces.

After the command is run to change the number of LAGs supported by the device, restart the device to make the configuration take effect.
