      @johnpoz said in No DHCP on pfSense VLAN with Cisco Smart Switch:

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

      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)
            Dell Optiplex 7040 SFF

            HPE 561T (X540-AT2), 2-port 10Gb RJ45
            HPE 562SFP+ (X710-DA2), 2-port 10Gb SFP+

              @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.

                        I would say this is pretty normal.

                        look at this sg350X :

                        trunk port with native vlan 2, works perfectly.

                            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.

                                    I plugged in a Linux workstation into switch port 20, which was a normal lan port.
                                    Got an IP from pfSense as expected.
                                    Configured switch port 20 as a vlan using the cli. Note: port 20 was not previously configured as a vlan.

                                    Output below of:
                                    show vlan
                                    sho run int
                                    show interfaces switchport

                                    Note: Switch port 1 is the pfSense Trunk port.

                                      Try to configure another port to vlan 10 from/with the GUI. Save the config and reboot the switch and test afterwards. I just checked one of my switches and it works straightforward.

                                        Configured switch port 23 to be a member of vlan 10 via GUI.

                                        Note: was not able to bounce the switch before the test as several users are using the system.
                                        Can try that later today if it would help.

                                          was not able to bounce the switch before

                                          There is no reason you should have to bounce the switch, the only time you should ever have to reboot a switch is if you are updating its firmware.

                                          Well @mvikman shows his output as showing that vlan 1 as native for ingress and says its working.. Which isn't what the output would express if you ask me.

                                          But yours isn't

                                          My sg300 correctly shows that native ingress on whatever access vlan I put on a port.. See my example output where I change the port 28 to different vlan and then back, etc..

                                          Maybe the sg250 is just crap when it comes to what the cli shows - but then why isnt this working?

                                          For a last hope go to general mode and specifically set the native vlan and the vlan your on..

                                          But sorry if your not seeing tagged coming into pfsense where you have a vlan setup - its never going to work.. That is for sure..

                                            The Interface Settings page in the GUI only shows two options for a port. Access and Trunk.

                                            Screenshot from 2023-05-23 19-01-04.png

                                            But the Port VLAN Membership page in the GUI shows Access, Trunk, General and Customer.

                                            Screenshot from 2023-05-23 19-05-42.png

                                            My question is can I change the port access mode to General in the cli if the General option in not available in the GUI? If so would it appear as General on the Port VLAN Membership page?
