Unanswered Question
Jan 7th, 2009

Hi all,


I have to upgrade firmware in one of my router 1800 series.


Can somebody guide me how should I proceed to upgrade firmware.


Just small doubt is there any particular difference between firmware & IOS?


If router running with old firmware is it cause to router reboots?



Regards,

Naidu.

The command to upgrade IOS and ROM Monitor differs.


ROM Monitor upgrade from TFTP server

Router# upgrade rom-monitor file tftp://ip_address/image_name


ROM Monitor upgrade from FLASH (if you doownload the image to FLASH from TFTP Server)

Router# upgrade rom-monitor file flash:image_name


You need to reboot the router after successful upgrade - by right, the router will reload automatically.


WARNING: Do not power off the router while the upgrade is in progress.
