nagi Posted January 28, 2022 Share Posted January 28, 2022 Just adding my own experiences, sry for the necro, maybe useful for someone else... port flapping With the same X520-DA2 combined with mikrotik S+AO00005 cable to a Mikrotik CRS305-1G-4S+IN used as a switch Jan 28 21:54:04 Storage kernel: bond0: link status definitely down for interface eth0, disabling it Jan 28 21:54:53 Storage kernel: ixgbe 0000:65:00.0 eth0: NIC Link is Up 10 Gbps, Flow Control: RX/TX Jan 28 21:54:53 Storage kernel: bond0: link status definitely up for interface eth0, 10000 Mbps full duplex Jan 28 21:54:55 Storage kernel: ixgbe 0000:65:00.0 eth0: NIC Link is Down Jan 28 21:54:55 Storage kernel: bond0: link status definitely down for interface eth0, disabling it Port flapping occured in one of the ports, the other I think just didn't log it, as it sure wasn't working, and while the switch showed link, unraid reported it as down. fw version: # ethtool -i eth0 driver: ixgbe version: 5.3.6 firmware-version: 0x80000231 expansion-rom-version: bus-info: 0000:65:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: yes Exhibited the same problem in another PC, (old Z79 based) but not in a third (Z99). The unRaid one is a X299 based newer machine. Very weird compatibility issue. Quote Link to comment
