Stack Port link down発生原因について

[n__o_]

Thank you very much for your help.

I would like to discuss a problem with a device in use.

The stack configuration consisting of the following two SWs is suddenly stopping at Stack Port link down due to an error, and although there is no fatal impact from the stacking, it is happening once a month. If you have any idea about the cause, please let us know. We are considering requesting send-back maintenance if we suspect equipment failure.

Stack components：

①M4300-12X12F(sw1-1)　Management　　 ②M4300-12X12F(sw1-2)　StackMember

Firmware：

12.0.13.8　B1.0.0.15

Be informed that a new firmware has been released for the M4300 switch models which is v12.0.15.7.  If your M4300 switch is not yet in the latest version, I suggest you to update it.  Kindly read the new features & bug fixes as well as you can download it here.
