The internet is down. Naturally, everyone turns towards the network rack and points at the switch.
Unfortunately, switches are rarely impressed by pointing.
Network problems can originate from damaged cables, loose connections, disabled ports, incorrect configuration, power issues or problems with the connected device itself. Even an illuminated port LED doesn’t necessarily mean the cable or connection is working correctly.
Good troubleshooting is about following the connection from one end to the other: check the cable, verify the link, inspect the port status, test with known-working equipment and then move further into the configuration.
So yes, the problem might be the switch. But pointing harder probably won’t help.
