  • Backing up IOS

    Hi

    i have found some threads on backing up IOS via tftp, i was wondering if there another way, i have seem references to using xmodem etc

    i would like to copy one IOS on a cisco cat 3750 to another, as it was deleted by mistake. the switch is fibre and would be tricky to use TFTP as i would have to set up a mini network at home

    if anyone could help that would be great

    Re: Backing up IOS

    Why do you have to setup a mininetwork at home to use a TFTP server???
    Just download 3cdaemon on your client and your good to go.

      would tftp work over hyperterminal?

      the switches are fibre and i have no gbics at hand today

        No. Hyperterminal uses serial communication, TFTP uses TCP\IP communication. HyperTerminal does have file transfer capability so if you connect your computer to the switch with a rollover cable you could transfer the ios file that way.

          Oh I understand you now..
          The switch has only fiber modules and no ethernet modules.

          Hyperterminal is indeed a good option, however be aware it can take some time before the file is copied.
          If you have a CCO account then it's maybe easier to download the right ios from the cisco site?

            Re: Backing up IOS

            Thanks Guys,

            the switches are fairly old so out of support

            i do not have a CCO account and they do try and slap a charge on.

            I think i will give the hyperterminal a go, would the commands be straightfoward?

            thanks
            Stu

              Re: Backing up IOS

              im almost there, i now have the .bin file and....

              hi, im having issues trying to copy across the .bin file using xmodem
              i type in the following on a 3750 with no IOS

              copy xmodem:flash:c3750-i9-mz.121-19.EA1d

              this comes up, which i think is ok:

              usage: copy [-b <buffer_size>] <src_file> <dst_file>


              i then try to copy using xmodem and it errors with

              no response from remote system

              pls can you help?

                      Re: Backing up IOS

                      This thread helped me find some answers so I thought I would share them...

                      At the switch prompt, using hyperterminal...

                      switch: flash_init
                      switch: load_helper
                      switch:
                      switch: copy xmodem: flash:your_file_name.bin

                      you will then see...

                      Begin the Xmodem or Xmodem-1K transfer now...
                      CCC_

                      Now open the pull down menu "Transfer" and select "Send File..."
                      Filename: Browse to and select your_file_name_.bin
                      Protocol: In the drop down menu select Xmodem
                      Click "Send"

                      Since the baud rate is so low you can speed things up for the transfer.

                      In the Hyperterminal window type...
                      Switch: set BAUD 115200

                      Now disconnect and change the baud rate in Hyperterminal to 115200. This will change a 3 hour transfer to 30-40 minutes.

                      Don't forget to set it back though, first in the hyperterminal window then in then in hyperterminal properties

                      Hope this helps!
