[SOLVED] What kind of device should you buy to test both ports and network device?

[Newtonian]

I've lost traffic from a couple of my POE IP cameras, as well as the garage door opener, which are all connected to the home network via ethernet.
I'm suspecting that either my switch is at fault or the ethernet cables that connect these devices to the switch have somehow been severed.

Is there a tester/monitor that can test both the operation of ethernet ports on a switch and the intactness of the ethernet cables that run to network devices?

There are devices like this, but they are expensive. Do you have a laptop? That is the cheaper option for port testing.
For cable testing I recommend this for the low cost option -- https://www.amazon.com/Tester-VXSCAN-Ethernet-Continuity-Loop-Back/dp/B08GK7CGGD/
For higher cost option -- https://www.amazon.com/dp/B097F7NG5D/?th=1
Both of these can check your POE. It is possible power is your problem.
