I don't know about other brands, but if you have Cisco Catalyst switches, many have a built in TDR that can help with determining if you have a cable/distance issue. In a building we completed a couple of years ago I found some of the AP runs exceeded 100m (conduit plan not followed), which did limit multigig speeds
If you are having POE and link issues not meeting your needs, did your low-voltage vendor commit any sins such as bundling Cat6a tightly together with zip ties and in long uniform bundles? If they didn't use F/UTP, those very pretty bundles/dressing can be murder on alien crosstalk. Lastly, for POE in particular, did you happen to use reduced size thin or ultrathin Cat6 patch cables? For newer AP's that require 30-60W, those thin Cat6a cables can contribute to power issues.

It looks like (from the description) the LinkRunner G2 and above will do the actual PoE load test I'm looking for (not just repeating what LLDP/CDP is saying the capabilities are). The LinkRunner 10G also appears to test the NBASE-T / 802.3bz standard for M-Gig. I've had some new construction recently where most all APs in a building link up at 5 Gbps, but a couple only link up at 2.5 Gbps. I would like to be able to test for that too. However..... The $6k+ price tag is fairly steep. Hopefully we can catch up again post-pandemic at WLPC soon. Is the domain change from CAD to Viszen a good thing? We can discuss offline if you prefer.

Starting at the LinkRunner AT model and going up, those have various PoE validation capabilities, increasing in capability as you head up to the LinkRunner G2 and then EtherScope nXG (which also does WiFi testing and makes coffee for you). Some of them can also be remotely controlled, so you can throw it to NOC, a tech, intern, whatever - and control it from the Interwebs.

I have some jacks that pass the installer's Category Certification, but are not passing the appropriate PoE to bring the APs online. I would like to be able to load test for 802.3af, 802.3at, and 802.3bt (at both 60W and 90W), as appropriate. I assume I would need to be able to set the load to apply (in Watts) and see the voltage level at the Powered Device. The usual constraints apply. Cheaper, but reliable is best.
