Problem with DHCP and a Cisco nexus 5020 10GB siwtch Not gettings ip addresses.
-
How is the switchport connnected to cxgb0 currently configured?
What, specifically, isn't working.
You are going to have to be very specific to overcome this language barrier.
The csgb0 port is connect to the trunk port on the switch ethernet 1/40.
Whats not working is i cant ping the router from the switch and the switch is not getting a ip address from pfsense.
Now i just did a test about hardware problem. The 10gb nic i have is a Chelsio T320-CO-SR.
If i'm correct if i connect cxgb0 directly into one of my hosts that port should get a ip address from pfsense.
I did that and i got no ip address.
I tried the same thing and igb2 which is opt2 on my router and connected it into my host and i got a ip address.Could this because of a hardware fault?
-
It could be a hardware fault but there is really no way to know with the information being provided.

What could i post to help this out?
I'm i correct on how dchp should work when directly connecting a end device?

I will ask one question at a time so we don't get lost…
What pfSense interface are you talking about? LAN, OPT1, or OPT2?
-
Opt1 is the interface I'm having problems with.@Derelict:

Please post a current screenshot of Interfaces > Assignments

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

interface Ethernet1/40
switchport mode trunk
switchport trunk allowed vlan 1-10 -
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!
