Hi All,

I'm not able to upgrade my 4506 switch.

problem is: my earlier IOS is in inbuilt flash & now I have uploaded my new IOS to Flash0. we have changed the boot sequence to flash 0 & after restart it goes to ROMMON.


Can u please let me know which command I need use or if any document is available.

Hi Ganesh,

Thanks for the reply.

My requirement is simple

I have a new image in my Slot0:XXXX.bin

1. which is the command to change the boot sequence to slot0?

2. Do I need to change anything in config-register?

Hi Ganesh,


Boot process involves two software images: ROM monitor and supervisor engine system code. When the switch is powered up or reset, the ROM-monitor code is executed. Depending on the nonvolatile RAM (NVRAM) configuration, the switch either stays in ROM-monitor mode or loads the supervisor engine system code.
