Trying to upgrade 4506 IOS Image but failed...

Unanswered Question

Hi Experts,

I have tried to upgrade the new IOS Image of 4506 but failed.. well, the IOS image already tftp inside to this switch. What I have done is as below:

1) Tftp to the switch

2) boot system flash:(IOS Image.bin)

3) reload

But seems like after reload, the IOS is still the old one.

Where do I go missing?

Thanks in advanced.

I have this problem too.

Hi Cindy,

Can you paste the output of "sh version" and "dir bootflash:"? Can you check if config reg value is set to 0x2102 from show version?
