I have two Dell enterprise servers connected via CAT over Link Local that would work fine initially but eventually all of the ports become unreachable, especially if i reboot one of the servers.
I then I unplug all of the network cables and toggle the ports in the UI then reconnect all the cables, it comes back… but then it eventually becomes unreachable again.
I am not quit sure I understand your problem. Or not familiar with the setup.
Are the two servers directly connected using a ethernet cable?
And you want to access the servers by and other network adapter?
I fixed the problem by converting them to static IP . I guess I was used to the way a different distro handled this by default and AlmaLinux handles it differently
