I am trying to upgrade my IOS on a Cisco Catalyst 2960 swtich.

I uploaded the new IOS to the flash directory via tftp, and can confirm via a "dir" command that it does reside there.

When I enter config mode and run the command:

boot system flash c2960-lanbasek9-mz.122-50.SE1.bin

it says invalid input character at ^ c

I tried

boot system flash:c2960-lanbasek9-mz.122-50.SE1.bin

and that did not throw an error, but after reload it still loads the old IOS.

show flash

to see if both the old and new image are present on the flash card.  If they are, copy the old image to your tftp location and then delete it with

delete <old_flash_image.bin>

Reload the switch and it should boot the new image by default.

The current (not new) flash image is in a directory flash:c2960-lanbase-mz.122-35.SE5

I can cd to the directory to see the actual .bin, but do not know the command to transfer this (since it is in the directory) to my tftp location.

I have tried:

copy flash:2960-lanbase-mz.122-35.SE5/2960-lanbase-mz.122-35.SE5.bin tftp://

copy flash:2960-lanbase-mz.122-35.SE5.bin tftp://

copy 2960-lanbase-mz.122-35.SE5.bin tftp://

but it can never find the file.

try changing directory to the image first and then copy.

cd 2960-lanbase-mz.122-35.SE5
copy 2960-lanbase-mz.122.35.SE5.bin tftp

verify that the filename is correct also.  zeros and 'S' often times look like 'O' and fives.

That worked; thanks.

My question is why it it wasn't respecting my boot system flash: command originally?

Was the image at the root of your flash card as indicated by your command or is it located in a directory?  

boot system flash:c2960-lanbasek9-mz.122-50.SE1.bin

Did you save the running config after setting the boot flash command?

The image was on the root of the flash card; I tried both ways (saving running config and not).

It doesn't look like you were doing anything wrong so I'm at a loss to explain why it didn't work.  I'm sorry I couldn't be more helpful on that point.
