I have a RB951G-2HnD with the latest RouterOS v6.43.2 installed. When I connect it at port 2 (or another port, this is not a PoE issue) with a Netgear FVS318N LAN port using a straight or cross-over 8p cable, LED indicates link on both devices, but the connection doesn’t work. It works when I connect MikroTik to an Ubiquiti gigabit switch and then connect the Ubiquiti with the Netgear. It works when I connect MikroTik to the Netgear with a 4p cable forcing it to go down to 100 Mbps.
Is there a known incompatibility with other hardware at 1 Gbps?
