Does the 2960 support tftp when it rommon mode? Can you set a 2960 to download it's image from a tftp server? If not is there any other way to get he bin file on the switch without waiting for xmodem?


Thanks

not possible by tftp you need to download image via xmodem if switch has corrupted image or deleted image.


switch: copy xmodem: flash:image_filename.bin



Go over this link - using xmodem

Unfortunately TFTP is not supported in rommon on the 2960 switch. You will have to use xmodem to load an IOS to the switch. There is a much faster way to upload the IOS. It will take minutes instead of hours.

Two years ago when I was a technician an engineer showed me how to unbrick a 2960 and I never used xmodem. I only used tftp so their is a way. In fact I installed a 3750 ios on a 2960 and all I had was Romon mode. I'm trying to duplicate what I did on my 2960 but its been two years and I can't remember all the steps. I've never used xmodem in my life. I'll update this post if I figure it out.

There is no way other than XModem on a 2960/2960G and/or 3750/3750G because these models neither have a USB port nor "tftpdnld" command.  With the newer switch that come with a USB port, it is as simple as plugging a valid USB thumb drive with the IOS BIN file.

I just read a post where someone booted an IOS from a tftp server and then installed the image. Their comment was why does cisco only put in the documentation one way of doing things (Xmodem) when their are three ways. and they pick the most conveluted way. He was working with a 2960.


I'm telling you I unbricked several 2960 switches and I never used xmodem.

Does anyone know why this feature isn't available? It gives you the options to set an ip address, gateway and an tftp server but not the tftpdnld command. I guess it is just as bad to not have enough space for two images at the same time...


Thanks guys.

If you change the console speed to 115200 a 2960 image will take maybe 5-6 minutes , its a big difference from 9600 .

Not the same.  2960/2960G does NOT have a USB port while the 2960S/X have.  If a 2960S/X boots up in ROMmon because of a failure of the IOS, use a USB thumb drive to boot the IOS works very well.
