6.4 Is it possible to upgrade the firmwares of our devices at once?
Yes. Use Command Runner tool (Sec. 3.6.1, p.80) to run the command for upgrading the firmware on the target devices. For Cisco devices, Change → IOS Software Distribution (Sec. 3.6.10, p.85) is convenient. Note that FTP and TFTP servers are required.
For Cisco devices : Change → IOS Software Distribution
