In order to perform interVLAN routing on the Cisco SG-300 switch, you must change the mode to Layer 3. I’ve been told in the new firmware, you can do this within the GUI however, I had issues with the latest firmware not showing my static routes.
WARNING: Changing the switch mode will erase any configuration on the switch. Perform a backup if needed.
After you connect to your switch to your network, it will obtain a IP. Log onto the switch using the default username and password (cisco, access). Enable SSH under services:
Establish a SSH session to the switch.
Hit enter at the log on prompt. Type in the default username and password.
Type in menu.
Tab to System Mode After Reset. Use the space bar to change your selection.
Tab to Save and Quit.
The switch will reboot a couple of times. It removes any previous configuration, so you start from scratch or restore from your backup.
Next post will be on how to setup the VLANs and routing.
