        Thanks for trying to shake the trees johnpoz!
        Started vlan config from scratch. Cleared all vlan config using GUI and only worked in the cli.
        Clearing the vlan config using the GUI appears to leave remnant config information when doing the config via cli. Is there a way in cli to clear all vlan config for a particular vlan?

        This is what I have so far:

        Roth-SG250-50P-1(config)#do sho vlan
        Created by: D-Default, S-Static, G-GVRP, R-Radius Assigned VLAN, V-Voice VLAN

        The one thing that looks odd to me is:
        do sho run int gi1 shows: Trunking Native Mode VLAN: 1 (Inactive)

        Does this output look correct?

          no not really..

          What does your sho tech show for port gi24?

          Name: gi24
          Switchport: enable
          Administrative Mode: access
          Operational Mode: up
          Access Mode VLAN: 10
          Trunking Native Mode VLAN: 1
          Trunking VLANs: 1,10
                                  2-9,11-4094 (Inactive)
          General PVID: 1
          

          For an access port - the native vlan should be the same as the vlan.

          It is never going to work if inbound traffic into the port that is not tagged does not get put into vlan 10.

              Nope - this switch seems worse then the shit tplink when they wouldn't let you remove vlan 1..

              Well time to start moving up the firmware releases from the one your on now - maybe they had one that wasn't broken..

                LOL

                I flashed the firmware back to the latest version before starting the cli-based config.
                I’m thinking it time to move on from this switch. Not worth the many hours invested for such a simple task!
                I always thought highly of Cisco switches but this one has caused me to sour on the brand a bit!
                Is there another bland / model smart poe switch that you would suggest I research?

                  @cannondale yeah I could see that, but I love my sg350's they have been rock freaking solid that is for sure..

                  how many ports you need/want.. How many of those poe? I have been keeping an eye for my unicorn switch.. No luck as of yet..

                  What poe are you looking for, I assume poe+, 802.3at, but there is the new 802.3bt in 60w and 100w options as well.

                    Something similar to what I have now would be great!

                    Capacity (mpps): 74
                    Switching Capacity (Gbps): 100
                    PoE: 802.3at PoE+, 802.3af
                    PoE Ports: 48
                    PoE Power (Watts): 375

                      Just for fun, as a comparison, here's the config from my CBS250 switch, looks almost identical in format/command wise as Cannondale's SG250
                      Everything is working as it should, pfSense interface has only VLANS configured.

                      pfSense Plus 24.11-RELEASE (amd64)

                      HPE 561T (X540-AT2), 2-port 10Gb RJ45

                        @mvikman Hey could you post the output of your show tech so we can see what it says the pvid is..

                        say ports 4 and 5 that have vlan 20 and 2000 on them.

                        Where his was showing..

                        Ingress UnTagged VLAN ( NATIVE ): 1

                        When the lan was suppose to be 10.

                                      Well, everything works even if it looks borked...

                                      Hmm... looking at the CBS-series CLI guide, "switchport mode" has these parameters
                                      • access—Specifies an untagged layer 2 VLAN port.
                                      • trunk—Specifies a trunking layer 2 VLAN port.
                                      • general—Specifies a full 802-1q-supported VLAN port.
                                      • customer—Specifies that an edge port connected to customer equipment. Traffic received from this port
                                      will be tunneled with the additional 802.1q VLAN tag (Q-in-Q VLAN tunneling).

                                      Also seems that those Ingress VLAN and PVID values are only used when the port is in General mode

                                        hmmm lets asume that the switch is working properly.

                                        if we set the workstation manually to the desired ip address/mask and gateway, there
                                        should be a ping answer from the gateway on the pfsense.
                                        just an idea to check this out.

                                        next : change the workstation port to lets say port 23 and try to set the vlan there

                                        and maybe : reboot pfsense and change the cables

                                          @pete35 all of that has already been done. Sniff on port going to pfsense no vlan tags - which has nothing to do with pfense

                                            we are using a lot of these switches and i never saw such problems. There are other problems with this switches but not within those basic vlan stuff. As these switches have a lifetime warranty from cisco, maybe a return and exchange will solve this issue. Otherwise im out of ideas what is wrong here.
