• My modem (Arris SB8200) firmware was recently updated to allow link aggregation, so I created a LACP on the WAN side. The first thing I noticed was either 6 or 7 Errors Out immediately upon startup of pfSense and approximately 300 errors a day. I can go back to one port in and everything is fine, but before I do, I was just wondering if there is anything I can do to troubleshoot to correct these to make this work?

    Switch out the cables is the first thing to try.

    So you see any interface 'events' in the system log? Does the modem give any useful data?


  • Yeah, I've tried several sets of cables.

    No corrected or uncorrectable errors. I've had nothing in the Events for the past couple days, but just checked and found a

    "Dynamic Range Window violation" RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW

    That might have something to do with it.

    Hmm, that seems more like something on the cable side.

    You could try setting at the command line:
    sysctl net.link.lagg.lacp.debug=1

    That will give you a lot more LACP logs on the pfSense side which might show something.
