Upgrade Cisco IOS and Backup

The next step is to upgrade iOS, where a good TFTP server software is used.

How to use it I won't say, go down

First to download to the corresponding iOS package, I use the official tar package here, so the process is a little different

# Debug The local tftp SERVER, and put iOS bag together enable# dir First look at the remaining space enough to put, if not enough, first erase flash: empty flash to continue, pay attention to the first backup! # Unzip the tar package into Flash archive tar/xtract tftp://local IP address/tar package name flash:# dir look at the full folder with the bin file name # View the configuration under boot show bootconfigure terminal# Modify boot boot to the new Iosboot System/folder name/bin file name exit# Check if the boot configuration is new Iosshow boot# write it in the "writing memory#" restart reload

By the way, backup

# Adjust local tftp serverenable# view iOS or profile paths dircopy Flash tftp# Source filename: Fill in the things that need to be backed up to the local path # Address or name of the remote host: fill in Local TFTP server address
