Network dropout when adding new VLANS to Lagg?



  • Hi all, I have noticed an issue that never used to be present going back a couple of versions. Whenever I add a new VLAN with my LAN side (lagg0) interface as the parent, I experience a loss of comms on that lagg for around 15 seconds.

    I just updated to the latest version hoping that this would fix it. However it hasn't.

    Has anyone else experienced this? Network card is a quad port Intel and I never used to have this problem in the past, I can't remember the version back then.

    This is a major, crippling bug. Help!

    Do you recall what version this did not happen on?

    I just did this and noticed no packet loss pinging the pfSense interface on another VLAN on the same lag. 0% loss pinging at 0.5 second intervals.

    192.168.223.1 is the pfSense interface address on lagg0.223

    Throughout this ping I created VLAN 1501 on lagg0, OPT17 on lagg0.1501, and enabled/numbered/applied OPT17.

    --- 192.168.223.1 ping statistics ---
    444 packets transmitted, 444 packets received, 0.0% packet loss
    round-trip min/avg/max/stddev = 0.169/0.664/159.686/7.556 ms
    

    At what point does the loss occur?

    When you add the VLAN?
    When you create the new interface using that VLAN?
    When you enable, number, and apply the new interface?

    What does the system log show when you add an interface?
    Does your switch log show anything interesting?

    ETA: No loss pinging through the firewall on removal of the same.
