The objective requires you to configure the IP address on the Ethernet interface connected to the PC. For this lab, we’ll use 10.1.1.1/24 for the PC and 10.1.1.2/24 for the Cisco device. Ensure that the IP Address you’re assigning to the Cisco device is in the same subnet as the PC. To complete the 3rd objective of this lab you’ll need a console session to a Cisco router or Switch.

Upgrading the Internetwork Operating System (IOS) on a Cisco device is a pretty common procedure as updated IOS images are released at least once every three months to fix bugs and provide new features and enable new device hardware.įirst off you’ll need a TFTP server installed and running on your PC with a crossover cable running from your PC to a router, or a regular patch cable running from the PC to a switch. You can however perform this procedure on GNS3 but you will not be able to reboot the device and verify a successful upgrade. Please note that this lab requires a REAL Cisco Router or Switch to perform as GNS3 does not load images from flash memory.

Once the new Cisco IOS Image is copied to the device flash memory, reboot the device and verify the upgrade was successful.Copy the new image file from the tftp server to your Cisco device, you will be prompted to erase the flash memory.Ensure you have Ethernet connectivity from your TFTP server to the Cisco device which you’re upgrading.Configure your TFTP Server and Cisco device to be within the same ip subnet, ie 10.1.1.1/24 & 10.1.1.2/24.Place the New Cisco IOS Image file in the TFTP Server Root Directory.
