Yesterday was working on my datacenter cabling my new proxmox network interfaces. I connected a network port to my mikrotik router. Before coming home I checked network linked condition and physically was ok , both leds blinking on both side , router and server nic. (eno1) Now , working remotely can see that server interface has no link. Very strange since interface at router is up. Any idea ? I never seen something similar (one side link ok and the other is down). Here can I share some outputs: root@pve2:~# ip link 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: ens2f0: mtu 1500 qdisc mq master vmbr0 state UP mode DEFAULT group default qlen 1000 link/ether a0:d3:c1:f5:37:08 brd ff:ff:ff:ff:ff:ff 3: ens2f1: mtu 1500 qdisc mq master vmbr1 state UP mode DEFAULT group default qlen 1000 link/ether a0:d3:c1:f5:37:09 brd ff:ff:ff:ff:ff:ff 4: eno1: mtu 1500 qdisc mq master vmbr2 state DOWN mode DEFAULT group default qlen 1000 link/ether 40:a8:f0:2a:18:80 brd ff:ff:ff:ff:ff:ff 5: eno2: mtu 1500 qdisc mq master vmbr3 state DOWN mode DEFAULT group default qlen 1000 as you can see eno1 is down ... while can see link up on the other connected side. I will change cable tomorrow, but wanted to share this experience with you. BTW , already tryed autonegociation , and fixed 100, 1000Mb. Regards. Leandro.
