        Please post the switch port configuration for the port connected to cxgb0.

            OK and a DHCP server is configured on the OPT1 interface in pfSense? Can you post that?

                OK then something connected to an access port on VLAN 10 on the switch should get an IP address.

                If not you have to figure out why not.

                I have found looking at the mac address table on the switch for that VLAN is a good place to start.

                You could also send the output of these commands entered into Diagnostics > Command Prompt (or run from the shell)

                ifconfig cxgb0

                ifconfig cxgb0.10

                  That's the funny thing. I don't a single ip address to the switch.

                  There are those commands ran.

                    That looks fine.

                    You need to look closer at layer 2.

                    What mac addresses are on VLAN 10?

                    Probably something similar to show mac-address-table

                      Vlan 2 is vlan 10 same config. I tried to redo it again.

                        I am pretty limited to what I can do after this. Everything looks fine on the pfSense side.

                        Maybe try to ping something on the 192.168.2.0/24 network from Diagnostics > Ping. That should put the pfSense MAC address in the switch's table. If not you need to figure out why not.

                        That switch certainly supports mirroring. Mirror that port to something else and wireshark it.

                        You are fortunately/unfortunately dealing with a 10G SFP+ port or I'd suggest putting a laptop interface on vlan 10 and plugging in directly.

                        Assign OPT1 to a gig-e port and try that?

                          After all your help i'm just stuck. Right now I'm returning my T320 card and buying a T520 10gb card and see if that was may problem. I'm have a really good feeling it it.

                          Will post when i have tested with the new card!

                          Thanks all for your help so far!
