Airfiber 11X & 2X reported port speed resorting to 10Mbps

Arrived at work to find port utilisation alerts on all our Ubiquiti Airfiber 11X and 2X. LibrenMS is reporting all their port speeds as now being 10Mbps. I’m not seeing this on any of our other Ubiquti gear (AF5x, AF5XHD, Airmax) or other vendor (Cambium, Mikrotik, Netonix etc) equipment.

Can anyone point me in the right direction as to why LibreNMS is suddenly doing this? The ports are definitely not 10Mbps. Setting them back to 1Gbps manually just gets overridden.

Hmm. Today it’s done similar with one of our SAF Luminas. Appreciate if anyone can shed light on what’s going on?
