I have 2 live ports and one of which has network flapping issue. ethtool -p runs but does not flash my ports. What else can I do without pulling the wrong fiber?

    read the label on the cable, I mean, you did label all your cabling, yes? – mforsetti Jul 13 '21 at 05:06
  • The standard label given there just makes the cable unique for tracing physically from switch to server. Any other workarounds? – peacht Jul 14 '21 at 06:03
  • ID the servers via the labels. OS will have flapping interfaces logged in syslog. – mforsetti Jul 14 '21 at 06:39
  • Yes I have the logs and the interface names already, thing is both are still live observed physically. How do I be sure I’m pulling the flapping port if the ethtool command doesnt work for my server. Basically looking for an alternative for ethtool -p – peacht Jul 14 '21 at 07:00
  • `ethtool -p` requires the driver to be able to control the LEDs, and not all drivers include them. probably try your NIC-specific driver or executable to do that. – mforsetti Jul 14 '21 at 08:27
  • Hmm meaning to say without that there is no other way? – peacht Jul 14 '21 at 09:10
