LLW stands for Limited Lifetime Warranty. LLW is for the Hardware so if there is a physical issue it will be replaced. I would recommend Sumit's suggestion first.

Thanks

we have seen on EXOS 15.1 and EXOS 15.2 base software version for X440 switch, some ports stops forwarding the traffic at random interval of time. those port never learn mac address. I would suggest to upgrade the switch to EXOS 15.,3.1.4 patch 1-33 and see if you are facing the similar issue.

So, are you think that my equipment have a hardware problem? Why the diagnostic extended can't find nothing?
What I need to do?
Thank you again!!
