Turn CISCO SG 300 into a Layer 3 switch

By | March 18, 2014

If you would like to turn the Cisco SG 300 into a Layer 3 switch the following are my notes on how to do just that.

Please know that if you plug this switch into a network that has DHCP running the default IP address will change from 192.168.1.254 to something else. Be ready to have an IP scanner utility such as AngryIP to search out what the IP address was changed to; or log into the system/device that is providing DHCP services and look it up.

Step 1 – Log into the CISCO SG 300-20 switch

You should be connected via the console cable using either HyperTerminal or Putty. The default username and password for the switch is “cisco” when you first log in you’ll be prompted to change the password. When you convert the switch over to Layer 3 this password change will be lost so be ready to set it again.

Step 2 -Menu

Once logged into the switch you will want to type “menu” at the prompt.

Arrow over to “Save” and press ENTER. You will now be prompted with a Y/N question. Answer as you see fit, knowing when you answer yes to resetting all of your settings will be lost.
