I've run into an issue with LLDP and I was hoping somebody could explain to me why on my edgerouter I only see Device ID and no Platform, Cap or Port ID from the router side. On the switch side (to the router) I see the Port ID (eth0 and eth2) and the system name. For now, please ignore the failover uplink (I'm also working on setting that up but am running into some issues).
