Step 12 Optional Configure the print variable. Step 13 Use the set command to display the ROM monitor environment variables to verify that you have configured them correctly. Step 14 Download the system image, as specified by the ROM monitor environmental variables, using the tftpdnld [-r] command.
Without the -r option, the command downloads the specified image and saves it in flash memory, deleting all existing data in all partitions in flash memory. Using the -r option downloads and boots the new software but does not save the software to flash memory.
Entering y confirms that you want to continue with the TFTP download. Because the system image is stored on an external CompactFlash memory card, you can use a PC with a compact flash card reader to format the card and copy a new system image file onto the card. However, this upgrade method is not commonly used. Step 1 Remove the compact flash memory card from the router.
Step 2 Insert the card into the compact flash card reader on a PC. Step 3 Use the PC to copy the system image file to the compact flash memory card. Step 4 Remove the card from the compact flash card reader. Step 5 Insert the compact flash memory card into the router. This section describes how to load the new system image that you copied into flash memory.
To load the new system image from the Cisco IOS software, follow these steps. Optional boot system flash0: system-image-filename. Optional Repeat to specify the order in which the router should attempt to load any backup system images. If the last digit in the configuration register is 0 or 1, proceed to Step 9.
However, if the last digit in the configuration register is between 2 and F, proceed to Step When prompted to save the system configuration, enter no. When prompted to confirm the reload, enter y.
Step 1 dir flash Note Determine whether the new system image is the first file or the only file listed in the dir flash0: command output is not required if it is the first file or only file listed.
Step 2 configure terminal. Use this command to enter global configuration mode:. Step 3 no boot system. Use this command to delete all entries in the bootable image list, which specifies the order in which the router attempts to load the system images at the next system reload or power cycle:.
Step 4 If the new system image is the first file or the only file displayed in the dir flash0: command output, you do not need to perform the following step. Use this command to load the new system image after the next system reload or power cycle. Step 5 Optional Repeat to specify the order in which the router should attempt to load any backup system images.
Step 6 exit. Use this command to exit global configuration mode:. Step 7 show version. Use this command to display the configuration register setting:. Step 8 If the last digit in the configuration register is 0 or 1, proceed to Step 9.
Step 9 configure terminal. Step 10 config-register 0x Use this command to set the configuration register so that, after the next system reload or power cycle, the router loads a system image from the boot system commands in the startup configuration file:. Step 11 exit.
Step 12 copy run start. Use this command to copy the running configuration to the startup configuration:. Step 13 reload. Step 14 When prompted to save the system configuration, enter no :. Step 15 When prompted to confirm the reload, enter y :. Step 16 show version. Use this command to verify that the router loaded the proper system image:. To load the new system image from ROM monitor mode, follow these steps.
Step 1 dir flash0: [ partition-number : ]. Note whether the new system image is the first file or the only file listed in the dir flash0: command output. Step 2 confreg 0x Step 3 boot flash0: [ partition-number : ] filename. Use this command to force the router to load the new system image:. Step 5 enable. Use this command to enable privileged EXEC mode, and enter your password if prompted:.
Step 6 configure terminal. Step 7 no boot system. Eliminate all entries in the bootable image list, which specifies the system image that the router loads at startup:. Step 8 If the new system image is the first file or only the file displayed in the dir flash0: command output, this step is not required.
Use this command to load the new system image after the next system reload or power cycle:. Created by Brett Murrell on AM. Created by Dinkar Sharma on PM. ISE 3. Created by deepuvarghese1 on AM.

GNS3 is an open source GNU GPL software that simulates complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches. GNS3 provides an intuitive graphical user interface to design and configure virtual networks, it runs on traditional PC hardware and may be used on multiple operating systems, including Windows, Linux, and Mac OS X.
In order to provide complete and accurate simulations, GNS3 actually uses the following emulators to run the very same operating systems as in real networks:. During our lab exercises, we use iosxrv-demo The only limitation with using this is it has AAA hard coded users and a rate limit of 2 Mbps. You are request to share your experience in case of any problem with this switch IOS image. Thank you for reading this post, have a good day..
