      @Jimbohello said in Urgent Lan Dropping:

      even static in my pc, no network

      If even static devices lose the network, it has nothing to do with pfSense. Perhaps a little more info would help.

      PfSense running on Qotom mini PC
      i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
      UniFi AC-Lite access point

      I haven't lost my mind. It's around here...somewhere...

        Maybe switch need to be to autoselect like pfsense !!

        Or both on static setting like 10gbe full duplex?

        Hard to diagnostic when nothing as Failed on 1 gig lan for almost 5 years

        Switch lenovo ce0152tb campus

        Thankโ€™s ๐Ÿ˜€

          First off, always use autoconfig, unless you have some specific reason to not use it. However, do some testing. If you have 2 computers with static addresses, can you ping between them? If not, it's likely a switch issue, as pfSense is not used between devices on the same LAN. Even with DHCP, it should take some time for a failure to be noticeable, as devices retain their address, until the lease expires. Break the problem into byte size pieces, so that you can see what's failing. What you're doing is like calling up a mechanic and sayimg "My car doesn't work, what's wrong?"

              If the switch port is set to fixed speed/duplex then the pfSense end should also be.

              On some 10G/1G dual speed ports we do see it is sometimes necessary to set 1G fixed to get a link.

              None of that should fail after some time though, it would either link or not. Something like an mbuf exhaustion would usually prevent traffic on all interfaces.
              Checking the logs for clues would be my first step here.

                  The main System log in pfSense. I'd also check the switch log for link failure on the port.

                    Master crash today all network down .
                    So i find out that all packet on the lan where getting error in or out donโ€™t remember ! Like million of error

                    I put back my intel 1000 pro
                    And everything look fine

                    So i thinโ€™k 3 possibility is possible
                    Failed nic
                    Failed fiber
                    Failed transceiver

                    Iโ€™ll let you know in the future

                      told you ill get back to you

                      after more than 2-3 month, no more crash

                      i did change both transceiver and fiber!

                      but i think the issue was witthing the switch

                      i realise that does switch work in tandem port 49/50
                      51/52

                      i believe that the fact that a server was attach in port 49 the issue was cause by having the pfsense lan (dhcp/server) port plug into 50. so i put both server on 49/50 and add the lan fsense to 51.

                      crash never occur since then!

                        Huh? Switches don't care what ports you plug stuff into.. Sure you could have a bad port.. But sure doesn't care what you plug into ports that are next to each other ;)

                          your absolutelly right ! but !
                          SINCE TECHNOLOGY INS'T ALWAYS PERFECT ! THIS SCENARIO IS POSSIBLE !

                          maybe it's a bug inside the swith ! inside the software or firmware or whatever !

                          anyway my problem is fix since 2-3 month

                          The 10G ports may be configured as stacking or as Ethernet in pairs. Configuring a
                          10G Ethernet port as stacking will also configure the paired link as stacking.
                          Likewise, configuring a 10G stack port as Ethernet will configure the paired link as
                          Ethernet. On the CE0152XB, ports 49/50 and 51/52 are paired. On the CE0128XB,
                          ports 25/26 and 27/28 are paired.

                              So combo ports? Yeah you might wanted to mention such details off the top..

                              Guess should of assumed they were combo from the numbers.. But without details of the special ports your dealing with. They are not your typical common ports on a switch, which don't give 2 shits if server or whatever is next to each other.

                                  Tandem is not the term have ever heard used.. Been in the business 30 some years, before there there were even switches. Never heard the term used to describe a combo port sorry..

                                  Do a google for tandem port switch, nothing.. do a google for combo port switch.. Gazillion hits..

                                  Tandem how would define it just means next to each other, one behind the other, etc.
