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)

@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.

Fresh run of show text attached.

Well yours is showing borked as well..
How is that suppose to work if untagged traffic comes into that port onto vlan 1

I would say this is pretty normal.
look at this sg350X :

@pete35 not talking about trunk port
-
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
-
@johnpoz
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 switchportNote: Switch port 1 is the pfSense Trunk port.

Searched the sniffer output for "vlan" and did not find that string. -
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.

Thanks for the suggestion pete35!
Configured switch port 23 to be a member of vlan 10 via GUI.
copied running-config to startup-configShow output below.

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. -
@cannondale said in No DHCP on pfSense VLAN with Cisco Smart Switch:

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..
-
johnpoz, thanks for continuing to hang in there!
The Interface Settings page in the GUI only shows two options for a port. Access and Trunk.
But the Port VLAN Membership page in the GUI shows Access, Trunk, General and Customer.
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?
-
Update:
Tried configuring port 20 (VLAN20) via cli to general mode.

Just a thought... the CBS-series GUI has a dropdown menu on the top right that switches between Basic and Advanced views, the Basic hides some stuff on the menus. Does the SG250 have that?
