Hello,
Need some help with a SonicWALL to Cisco switch module configuration.  The Cisco switch module is a 20-port switch module in an IBM Bladecenter.

Currently, the SonicWALL firewall has WAN X1 connected to the upstream provider.  It's IP address is 64.xx.xx.21.  LAN XO is IP 192.168.6.1 and connected to Cisco switch module port GigabitEthernet0/17.  The configuration of GE0/17 is as follows (it's the default config):

interface GigabitEthernet0/17
description extern1
switchport access vlan 2
switchport trunk native vlan 2

I have a server blade connected to GE0/2, and I would like to have it's traffic separated to a different VLAN.  I do have traffic on VLAN2 however from GE0/1 that is on the 192.168.6.x class and that needs to stay functional.  GE0/2 configuration is here (again, default):

interface GigabitEthernet0/2
description blade2
switchport access vlan 2
switchport trunk native vlan 2
switchport trunk allowed vlan 2-4094
switchport mode trunk
spanning-tree portfast trunk
spanning-tree bpdufilter enable

I can create a VLAN interface on the SonicWALL X0 Port and give it an IP address of 192.168.7.1, tagging packets as VLAN 3, but I cannot get the packets to flow over to GE0/2.  I would like all traffic going to/from GE0/2 to be VLAN 3.  How can I achieve this?

You need a device to route the packets.    Either a Router on a stick scenario, or (if this switch is capable) use the switch itself to route.  

IF you want to use the switch, Create the vlans and assign the switch an IP in each vlan,

interface vlan2
192.168.6.2

interface vlan3
192.168.7.1


and enable IP routing

ip routing



Devices on vlan 3 use 192.168.7.1 as the gateway, devices on vlan 2 use 192.168.6.2 as the gateway.   The switch must have a default route pointing out to the next hop gateway at 192.168.6.1

The firewall should be capable of routing the packets, shouldn't it?

"ip routing" is not a valid command on this switch.

Can you send the output of a SHOW VER.  

Oh and 1 thing I forgot.  You'd need to add a static route on the Sonicwall for destination 192.168.7.0/24 to 192.168.6.2.

Fixed it myself.  Just had to change GE0/17 to switchport mode trunk.
