Then give command similar to ' boot system flash:/.bin' to boot from new bin image.

Copy new IOS image from tftp server using ' copy tftp: flash:.

If still less space is left then take backup of old IOS image and delete it.

(Note that switch must be connected to tftp server through network.) Once you have spent ages configuring your Cisco router, you want to make sure that the configurations.

Then we can use following method to upgrade switch IOS using telnet / console connection to switch and tftp server. Backing Up a Cisco IOS Configuration to a TFTP Server. Normally if the previous image of switch IOS has web interface (flash:/html directory present) then we can use Cisco Network Assistant(CNA) available freely from Cisco website to upgrade switch IOS safely.Д«ut sometimes the web interface would not be there (either to save space or corrupted).

Next, we need to transfer the file from the TFTP server to the flash memory of the switch. We need to place the image file to a TFTP server that is reachable by the switch: 2.

If there are no boot system commands in the configuration, by default, the router loads and runs the first valid Cisco IOS image in flash memory.ДЇinally, as shown in Image, the show version command can be used to verify the software image file. Router (config) # boot system tftp: //3.bin Specify the TFTP server as the source of the Cisco IOS image, with ROMmon as backup.

Router (config) # boot system flash0: //3.bin

Specify the flash device as the source of the Cisco IOS image:.

As shown below, the boot system command is a global configuration command that allows the user to specify the source for the Cisco IOS software image to load.ДЇlash0: //3.binДЄmong the available syntax options are the following:.

Several boot system commands can be entered sequentially to provide a boot plan that has fault tolerance. Once you start the router, use the show version command to verify that the new image was loaded.Дuring boot, the bootstrap code analyzes the boot configuration file in the NVRAM to detect boot system commands that specify the name and location of the Cisco IOS software image to load. Reload the router to boot with the new image. To update the copied IOS image once that image is saved in the router's flash memory, configure the latter to load to a new image during boot using the boot system command.

A new image file ( 3.bin ) will be copied from the TFTP server in 2001: DB8: CAFE: 100 :: 99 to the router.ДЄfter issuing this command with the specified destination and source URLs, the user will be asked to enter the IP address of the remote host, the name of the source file and the name of the destination file. Image illustrates how to copy an image of Cisco IOS software from a TFTP server. In this example, IPv6 is used for transfer, to show that TFTP can also be used over IPv6 networks.

Д¦8831808 bytes copied in 363,468 secs (269058 bytes / sec)ДЄfter issuing the command using the specified source and destination URLs, the user is requested to enter the name of the source file, the IP address of the remote host and the name of the destination file. Source filename ? 3.binДЄddress or name of remote host ? 172.16.1.100Дestination filename ? Copy the image to the TFTP server using the copy source-url destination-url command. The sample file is 68831808 bytes in length. Use the show flash0: command on the router to determine the size of the Cisco IOS image file. Verify that the TFTP server has enough disk space to support the Cisco IOS software image. Ping the TFTP server to test connectivity. Make sure there is access to the network TFTP server. To back up the Cisco IOS image on a TFTP server, follow these three steps: You can learn the Cisco IOS name convention here. In following figure, the network administrator wishes to back up the current image file on the router ( 3.bin ) on the TFTP server at 172.16.
