      I will try to find a description of this switch, but in the meantime...

      the following:

      HP switch to Unifi switch, a trunk must be created
      (between two switches are usually required to pass through any VLAN later)

      • the trunk also (cleverly) gets a LACP (LAG)
        (because the VLANs consumes bandwidth)

      everything on the trunk except VLAN1 is tagged, VLAN1 is untagged, because it is native

      as I wrote, to Cisco it is not enough to have only ports associated with a VLAN
      but it is also necessary to assign the LAG (with LACP) on the trunk itself to a VLAN (of course, to which the ports are also assigned)

      Cats bury it so they can't see it!

        This is interesting.. on the Unifi AP, what gets assign to vlan 1? The IP for the AP? The APs are all connected to the Unifi switch

          Vlan 1 is use for Switch Management, my internal Clients, SSID 1 and Switch, AP Management.

          But you can set SSIDs to Tagged Vlan only, it is your decision.

            SSIDs are tagged appropriately with vlan ids.
            Plan is to config the mgmt vlan last.
            My main issue is trying to get HP switch VLANs setup properly

              AP Management VLAN always untagged.

              Management VLAN can be tagged to pfsense if there is the GW or to the Unify Switch and there is the pfsense with the GW.
              The default GW is idependet from tagging.

              Set operator pw first, then manager.

                This is the vlan port config. (Pic1 & 2). if I set the LACP 24 to PVID 20 and Tagged only. Unifi switch and APs loses connection to pfsense. Which make sense because it is only allow vlan 20 tags to go through.. vlan 1 is blocked.

                Making LACP 24 a member of vlan 20 should allow vlan 20 tags to pass through. (Pic 3 & 4).However, devices cant access internet.
                pfsense rules allow vlan20 net to dest any.. what is blocking internet access? Disabling vlan20 on Unifi. fixes internet issue.

                  Switch to Switch Uplinks use normaly untagged vlan 1, this is important if you use STP Mode MST.

                  The Vlan 20 tagging look good.

                    I think i know why vlan20 traffic is not getting to pfsense vm. The port which ESXi is connected to HP switch needs to be a member of vlan 20. vswitch is already set to 4095. All traffic is just passthrough.

                      Making LACP port member of vlan20 did not resolve DHCP issue. How do i trace where the request is being dropped?

                            I usually use Wireshark on Cisco systems with the following method.
                            If your HP switch knows the SPAN protocol, your life may be easier.

                              Any managed switch should be able to do that. Even my crappo TP-Link can. I first did it with Adtran switches several years ago.

                                TP-Link...hmmmm, though I wouldn't use it for letter weights either (hahaha)

                                  Some TP-Link switches have problems with tagged VLANs. Mine doesn't seem to have a problem with port based VLANs though, though it likely would with tagged VLANs. I have it configured to use as a data tap, so I can monitor Ethernet connections with Wireshark.

                                    Is there a big price difference in your country between the Cisco SMB series (SG350, SG350X, etc.) and the TP-Link devices?

                                    Pls don't think that, I hate TP-Link so much, but we haven't used it in a long time, so I only have experience up to the TL-SG series

                                    BTW:
                                    we deal with AoIP stuff a lot (DANTE protocol) TP-Link is totally dead on the IGMP and DSCP QoS themes

                                      I paid about $100 for a Cisco SG 200-08 switch, but that TP-Link TL-SG105E was only around $35.

                                      BTW, my early experience with managed switches was with Adtran, as my employer was their Canadian distributor. Adtran's AOS was pretty much a clone of Cisco's IOS.

                                        I understand...

                                        just a story:
                                        for me, TP-Link customer service answered a simple question for three months...
                                        the question is was the factory SFP modules know DOM / DDM?

                                        then I gave up and tried no further
                                        (of course, there was no reference in the description)

                                        -there was an SFP diag menu in the GUI of the switches
                                        didn't give any info about any DOM / DDM capable SFP, so we thought it only works with his own...

                                        the joke is that as it turned out they don't produce SFP modules with DDM / DOM capabilities

                                        then what is that menu for in the GUI?

                                          My experience with them was in regards to that VLAN problem, but with my access point rather than a switch. The problem is that multicasts would leak from the native LAN to the VLANs, which meant that devices on the VLAN/2nd SSID would get config info from the native LAN. When I called support, they insisted that that was how VLANs were supposed to work. Eventually, I talked to 2nd level support, who agreed it was a flaw. However, there was no fix forthcoming for my AP.

                                            HP 1800 do support port mirroring. tried wireshark but monitor mode option is greyed out.
                                            airmon-ng needs to be installed before trying to enable monitor mode.

                                            BTW, does ingress filtering needs to be enabled on the LACP port on the HP switch connecting to the Unifi switch? I left it disabled.
