I have a Cisco 4506 Switch with a Supervisor Enigine IV that I want to upgrade the IOS on. So I downloaded the IOS from Cisco, used my TFTP server to copy the image to the switch, but now I can't find the image. I did "copy tftp flash" command when copying over the IOS, but there isn't a "show flash" command on this switch so I can't see it. I did a dir: bootflash and can see the old image is there, but no the new image. I tried to tftp the new image to the bootflash dir but it didn't work. Any idea what directory the new image that did successfully copy to the switch is? thanks.
