2950 IOS SWITCH ISSUE

I have another Cisco 2950 24 Layer 2 switch, even though it must have some funtionality to allow 'ip addresses' on each interface!!

the tftp server located on the pc can ping the switch and vice versa.


After doing a 'sh flash' it confirmed that the new ios of 3mb that needed to be copied to the switch, meant that I had to 'delete' the current ios.  Ive also rebooted the switch and it is the prompt: (I know I shouldn't have)

switch:

I have nothing on the switch I want to keep!!!!!!!!!
how can i install a fresh ios as not sure how to get out of prompt 'switch'?

After doing a 'sh flash' the ios is now not in the list, but on trying to do:

copy tftp flash
ip address of the  tftp: x.x.x.x etc etc, it keeps saying error!!

does anyone know why?

If you are are at the switch prompt and can ping, you have IOS loaded and running on this switch.  When attempting to TFTP the file, are you sure the name of the file is correct (including capitalization)?

Before rebooting I was able to ping.
Although I know I shouldn't have rebooted, but because the switch was not allowing me to:
'copy tftp flash' - even though everything was pingable im not sure why.  As i 'cut and paste' the ios and typed manually the 'tftp ip address', but it kept showing error, hence reboot!!!:((

so now stuck at:

switch:

Ok....   Looks like you will need to console onto the switch and use xmodem to copy the file (this will take several minutes.

Here are the steps from Cisco:

http://www.cisco.com/en/US/products/hw/switches/ps628/products_tech_note09186a0080169696.shtml?referring_site=bodynav

Enter the commands flash_init and load_helper.

Copy the image to the Flash using HyperTerminal for Microsoft Windows, or another terminal software program. The command on the switch is copy xmodem: flash:filename , where filename is the name of file that you downloaded. With HyperTerminal, use the TRANSFER -- SEND FILE option using the XMODEM protocol. Start the XMODEM download within three seconds. Otherwise, the switch times out the XMODEM copy.

When the XMODEM request appears, issue the appropriate command on the terminal-emulation software to start the transfer. Copy the software image into Flash memory. The command to issue is switch: copy xmodem: flash:image_filename .

An example is shown here.

    switch:
    switch: copy xmodem: flash:c3500XL-c3h2s-mz.120-5.1.XP.bin

    CCC..........................................................................          

    (BEGIN XMODEM DOWNLOAD ON TERMINAL SOFTWARE NOW)

    File "xmodem:" successfully copied to "flash:c3500XL-c3h2s-mz.120-5.1.XP.bin"


This should reload the IOS for you after a reboot.

yes tried that:

switch: copy xmodem: flash:c3500XL-c3h2s-mz.120-5.1.XP.bin

on both baud rate 9600 & 115000, did not respond it says!
jlindlerCommented:
Did you load flash_init and load_helper?    Also, you have to start the file transfer on the client machine for the file to be sent.
mikey250Author Commented:
im doing it again, it looks like its working, will let you know.
mikey250Author Commented:
yes ran the flash_init & load_helper again!

Ok....

Make sure you have the bin file on your computer.  

    Issue the copy xmodem: flash:filename command on the switch.  Filename here and below should be change to the file name of the IOS file you are trying to send.

    Here is an example:

        switch: copy xmodem: flash:c2955-i6q4l2-mz.121-13.EA1.bin
        Begin the Xmodem or Xmodem-1K transfer now...
        CCC

    From the top of the HyperTerminal window, choose Transfer > Send File.


    Choose the Xmodem protocol in the Send File dialog box and click Browse in order to select the Cisco IOS image (.bin file) that you downloaded previously.


    Click Send in order to begin the Xmodem transfer.


    The Xmodem file transfer begins. This transfer can take up to 2 hours, which depends on the size of the image.

        File "xmodem:" successfully copied to "flash:c2955-i6q4l2-mz.121-13.EA1.bin"

        !--- If the Xmodem file transfer fails for some reason, restart the process.
        !--- If the Xmodem file transfer is successful, you return to the
        !--- switch: prompt.

        switch:

Boot the new image that you just copied over with the Xmodem procedure.

Issue the boot flash:filename command, as this example shows:

    switch: boot flash:c2955-i6q4l2-mz.121-13.EA1.bin
    Loading "flash:c2955-i6q4l2-mz.121-13.EA1.bin"...###############################
    ################################################################################

    !--- Output suppressed.

    Press RETURN to get started!
    Switch>

    !--- The bootup was successful.
