Strange Drops

Hi to all,

We have a strange drop packets every one or two ours for about two minutes. From the lan we can't reach any destination on the WAN. Now we have XG 18MR1  and a Swithc layer 3 as Default gateway of the LAN. Also PortE0 ( LAN ) show many dropped packets.

Any idea to the question ?

Thanks Marco

  • Hello Marco,

    Thank you for contacting the Sophos Community!

    Does this happen only in one interface Port?

    Like if you have Port1 and Port 3 sets as LAN does the traffic stops for both Ports or only one?

    Can you please try running the following command and monitor if the issue persists, if it persists please reverse the command by adding default after Port1 (You can use Tab autocomplete)

    console > system diagnostics interface-driver-settings set Port1 offload tso

    Also if you run ifconfing from the Advanced Shell (5>4) does the interface with the issue shows any error?

    Regards,
