Connect a port on the SonicWall Switch to an available port on the firewall. Use a CAT5e or CAT6 cable (that is, RJ45 to RJ45) when connecting to an RJ45 port, or use a fiber optic cable when connecting to a supported SFP interface.
When adding a Switch manually, first check that it is configured to factory defaults. This can be ensured by depressing the reset switch button for 10 seconds or more. The Switch can also be factory defaulted from the Switch Local UI, or the Command Line Interface accessible through the console port.
To change the Reserved VLAN range on the firewall, do so before adding the SonicWall Switch. If the Reserved VLAN range changes after connecting the Switch, then the Switch must be removed and re-added.
Log into the SonicOS management interface and navigate to DEVICE > Switch Network > Overview> List View. Click on Add Switch as shown below.
The ADD SWITCH dialog appears:
In the Add Switch dialog box, populate the following fields:
Switch Uplink: Select the number of the Switch port that is connected to the firewall.
The Firewall Uplink interface and the Switch Uplink port are physically connected to each other. Refer to About Uplink Interfaces in the Configuring Basic Topologies section.
Under ADVANCED SETTINGS, configure Spanning Tree and Jumbo Frame size settings:
Go to Overview > Physical View, the new Switch will appear graphically with the ports linking the Switch and the firewall indicated.
