xg-7100 to and from intel nuc ethernet not working

erasedhammer

I just plugged in my intel nuc to eth5 on my xg-7100 and the connection between them does not appear to be working, despite the physical connection being up.

Items checked on nuc (running debian 10):

ifconfig shows correct IP and subnet - shows almost 1MB of transmit, 0 receive bytes
netstat -rn shows correct routes
arp -a hangs and eventually shows incomplete on mac addr for gateway
resolv.conf and network/interfaces both have correct ip addr for device and gateway.
ufw firewall disabled
packet capture shows the nuc attempting to contact the internet for dns and ntp, no responses
Port LED shows blinking green, and amber (for nuc, amber means 1000base-t)
Device has been restarted a couple times

Items checked on pfsense:

Firewall rules allowing traffic into and out of subnet to/from the nuc.
ARP for the nuc not showing up, I added static arp entry and still no communication
test port and ping from pfsense itself times out
clients going to the nuc (ssh & https) time out
Packet capture on the interface of the nuc shows traffic attempting to contact it and no responses
Tried different ethernet cables, checked with a rj45 cable tester. Cables are good straight through
in pfsense under switch / ports, eth5 is configured with correct port VID and shows as Active 1000baseT <full-duplex>
Port LED shows green
Firewall has been restarted

How do I solve this?

This is definitely not the first time the marvell switch and its ports have conducted black magic on new connections. In the past problems have just solved themselves over time, I have no clue why.

I'm just spitballing here...

Do you have a dumb network switch that you can plug in to the middle of this setup? NUC to dumb switch, dumb switch to pfsense. I know it doesn't make much sense, but sometimes it works. It typically shows that there's a network card problem, or the 2 network ports on the devices can't sync successfully.

Thats what I originally had to connect the nuc up to the firewall.
It was connected to a dumb cisco 5 port switch and that switch connected to pfsense. That worked just fine.

The dumb cisco switch is in a different room, and I wanted to move the nuc to the rack where pfsense is.

Resolved. I keep forgetting to check the vlan tab under switch...
I keep getting thrown off by the xg-7100 have two places for vlans...
Added the port to that and it works now.
