I guess this belongs in this category.
A new card is now available on HACS to show the status of your switch ports called switch-port-card. It features port status, speed, Rx/Tx, Vlan and given port names as well CPU and RAM load. It needs some entities to be set and the code on github gives some entity files that you can copy paste and adjust where needed. GitHub - partach/switch_port_card: This Home Assistant card shows the status of your switch ports. See readme for details.
While making this i found it a bit much regarding all entities that needed to be created per port. So working on switch-port-card-pro integration (with card included) to do all that heavy lifting. Work in progress…
Could be a good next extension. Need to think how from a UX perspective it remains not too bulky. Adding it to information on hoover will be quite easy to add (but again needs some entities).
