Since I have a EX2200, I thought I should at least upgrade its firmware. But JunOS firmware upgrade didn’t go as user-friendly as I thought. Anyways, this is what I did to upgrade from 11.1R3.5 to 12.3R12.4
Key Notes:
- Don’t use the Web Interface to upgrade. It is slow and does not seem to work.
- Upload the firmware to a web server that allows direct linking.
- The reboot process takes more than 15 minutes. Do not be alarmed if the switch seems to be dead during the process.
Steps via Cli
root@JunSwitch:RE:0% cliroot@JunSwitch> request system software add "Web Link here"
Fetching package...

WARNING: A reboot is required to install the software
WARNING: Use the 'request system reboot' command immediatelyroot@JunSwitch> request system reboot
Reboot the system ? [yes,no] (no) yes
Shutdown NOW!
root@JunSwitch> show version
