VLan not working
I have:
Switch 1 connected to a PC with that port configured with Vlan2.
Connected to switch2 via a standart port that is also on Vlan2
Switch 2 connected to switch1 via a standard port configured for Vlan2 (same cable as listed above, only one connection between the 2 switches)
Connected to a firewall with the port configured for Vlan 2
Firewall connected to the internet
connected to switch2 via a port that is configured with the default Vlan0 and a subinterface with Vlan2.
I cannot ping from my PC on switch 1 to the lan interface of the firewall.
What is the best way to diagnose this?

thats if i have understood your configuration :)

Only the firewall is configured with a subinterface, the Switches are not.
When you say a trunk, do you mean 2 network cables to the switch, one on Vlan0 and one on Vlan2?

It's a mid range Sonicwall.
make the port (connecting the switches) on both the switches as trunk rather than access (currently on vlan2).
i.e. :inter-switch connectivity to be done through trunk port

you do not require to trunk the ports connecting the switches. As long as only one vlan is to travel over the links your setup is fine if you remove to subinterface on the firewall. However if you are going to use sub-interfaces on the firewall then the link between the firewall and the switch will need to be trunked. Otherwise you can remove the subinterface and place the main interface into vlan 2 on the firewall.
If you are going to be adding more vlans to your network in the future then trunking all the interswitch links and the link to the firewall would be the way to go as it will save you a lot of config and headache in the future.
Trunking is not done by adding an extra cable for the other vlan but instead it is a configuration to allow more than one vlan over the link.

If your firewall doesnt have any specific interface configuration then VLAN 0 will be the VLAN and thus it wont work.
