No DHCP on pfSense VLAN with Cisco Smart Switch
-
interface GigabitEthernet1 switchport mode trunk switchport trunk allowed vlan 1,10,20I'd remove vlan 1 from the allowed line on your trunk (Gi1).
Too many odd things that aren't adding up. Rolling back the firmware may work, but if it doesn't, I'd still recommend rebuilding the config from scratch from the cli. You'll likely save yourself countless hours of more troubleshooting.

Thanks for the suggestions guys! You both have given me some additional options to try.

He is using that, as the native vlan.. Its just untagged so he wouldn't remove it.

Just an update. Successfully rolled the firmware back to v2.4.0.94.
This scrambled many of the previously configured settings in the switch so had to reconfirm everything to get back to where I was before the roll back. Unfortunately, the roll back did not change the PVID issue.Changed port 24 (VLAN10) and port 22 (VLAN20) from Access to Trunk. Note that those are to only two options!
Ran show tech-support again (output of port 22 and 24 below). Both still show

Thanks again! -
@johnpoz I don't have access to a Cisco SG-series switch.
-
@derelict NP - thanks for chiming in.. It was a shot, you and Steve normally have all kinds of stuff ;)

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:

do sho run int gi1 shows: Trunking Native Mode VLAN: 1 (Inactive)Does this output look correct?

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

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: 1For 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)

@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.
