pfsense 2.7.2 and IOCREST 4 port 2.5gb NIC (Intel I225-v)
-
Hello everyone!
I seem to be running into a strange problem with a NIC that should be working. I purchased an IOCREST 4 port 2.5gb NIC which is based on Intel I225-V chips. The system did see it when it was installed, and after some strange behavoir when it didn't recognize a link plugged into it, it appeared to be working as intended.
The problem I just noticed is one of the ports is connected to my Spectrum Modem which has a 2.5gb ethernet port, and it was showing that the interface auto negotiated 2.5gb. When I went into the dashboard this morning, it was showing that it had changed the speed to 1gb. So I went into the WAN config and changed the speed and duplex to autoselect from default. It did not like that, and the interface started bouncing up down... so I went back in and changed it to default... and it once again auto negotiated 2.5gb and the link has been up for the last several hours.
My question is, any idea what would make this interface unstable? My understanding was this card was now supported?
Appreciate any and all thoughts and suggestions.
Thanks!

The igc driver/hardware can only be autoselect. For some reason setting it to that specifically can cause it to go into a loop of some sort as your saw.
You could try setting it to 2.5G which will prevent it linking at 1G. It still negotiates that though so if the modem for some reason stops allowing 2.5G it will just fail to link.
