Yesterday, we moved from a stack of x440-48t switches to a stack of X440G2-48t-10G4 switches and a large number of systems are unable to connect to the network. They are a mix of IPs set statically via DHCP reservations and others that just use whatever address they pull. They cannot be woken up via a WoL broadcast. The systems that don't wake up can be manually powered on and then need to have the IP address set in Windows to what it is statically set to in DHCP, rebooted, then set to use DHCP again and they can then connect to the network. The switches are running 22.4.1.4 patch1-2. All systems with issues are running Windows 10 and are on a mix of hardware.
We also replaced the core switch that this stack is connected to with a X460G2-24t-10G4 22.4.1.4 patch1-2. A number of months ago, we had attempted to replace just the core switch and we saw this same behavior with systems not being able to connect, so we went back to the old hardware and hoped that replacing the core and the desktop switch would avoid the issue but it did not.
Has anyone heard of this? Is there some setting that we are missing? We do have a policy in place to send traffic on port 4000 (used to WoL) to the correct VLAN which is working, since most systems wake.
