Hello Community, i have a strange problem with my M4300-52G stack. We have a 4xStack and a 2xStack and since the update to the latest FW 12.0.7.17 we have on both stacks problems with LAG. Randomly the server on a LAG lost the connection to the network. Only clients on the same intra-vlan subnetz can access the server. I cannot reproduce it. To solve the problem, we need to make a cable test on one port of the LAG. The support told me that i need to make a downgrade of the firmware and start with an incremental update till the latest firmware 12.0.17.7. That is not practical in a production environment. Has somebody else the same problem? Do you need more information? Thanks!
The company works 24/7 a year, we have only two slots a year for maintenance. Now it has even gotten so bad that every 10 minutes the server goes offline. Luckily, the customer doesn't notice anything because the traffic works in the intra-vlan. My case number -> 46440776. Thanks!
