Gateway down for 1 min, up again



  • Hello,

    I have a 2.3.4 system (I know I will upgrade it soon!), with 3 WANs, 2 of them are equal (VDSL 50) and one is ADSL 15. I have created a group with Tier 1 of the 2 equal and Tier 2 of the non-equal ADSL. I keep getting notifications on the WANs when they used heavily (and latency goes up), like this one:
    MONITOR: OPT4_WAN_DHCP_DHCP is down, omitting from routing group MainOut
    8.8.8.8|172.20.20.205|OPT4_WAN_DHCP_DHCP|536.956ms|587.255ms|3%|down
    after one minute, specific WAN goes up again.
    No traffic shaping.
    I guess this is normal, or is there a better approach on this?

    Best regards

    Konstantin



  • I have exactly the same problem on 2.4.4 maybe once or twice a day on both of my WANs. There's nothing in the logs of my actual VDSL-modems besides the daily reconnects at 4 a.m. for the first and 5 a.m. for the second connection. Those reconnects do not trigger a "gateway down" alert, though.

    As I get notify by mail about any gateway down event, I'd really like to sort this out without setting the thresholds so high that a real gateway down event would go unnoticed.

    Best,

    Stephan

    Yea, I'm noticing Gateway down events occasionally since I upgraded to 2.4.4, Never had this issue with 2.4.3. Looks like it was down for about a minute this morning around 9:43 am CDT. System cleared and came back up and is working. I'm using the default gateway that Spectrum supplies on my cable, DHCP, internet. Hope this is not going to be a continuing issue.

    Not sure what to change that would prevent this from happening as I've never had this problem before.



  • I have the same with 2.4.4



  • the same here. occasional disconnects on one of two WAN interfaces since the 2.4.4 update



  • I somehow don't experience this behaviour anymore. No entries in System Logs. I set the thresholds to 300/750, 20/35 and intervals to 5000/2000/15000.

    It may be a coincidence, but I've update squid to the latest version just that day or the day after.



  • @sko Hi,
    Those intervals, what do they represent:
    Probe/Loss/Time?
    What about Alert Interval?



  • @r0sebush
    the order as they appear in the gui, left out Time Periode, this is set to 15k
