I have a brand new MX84 which deployed in my company branch, but when i try to connect MX84 Internet port to ISP modem, the interface is up but in red LED. Dashboard also showing WAN 1 is in failed condition. I've already try to change interface speed from auto to every option & also trying to swap cable but still no luck. When i try to directly plug modem to my laptop there is no issue at all. Does anyone know what red interface LED mean within MX product ?
So our existing setup is using Mikrotik RB which will be replaced by this MX84. For workaround, I decide to connect MX84 WAN 1 port to this Mikrotik and making some sort of bridge mode and this is works.
I can talk to my ISP to see whether they see some traffic or not, but i'm more curious about the red interface LED mean, do you ever seen this before ?
Also i think this is related to MDIX problem since the modem itself is fairly old but i am not sure
