I have a Cisco Switch Catalyst 2950, nevertheless it does not have the option "crypto" in order for me to ssh to it. Any suggestion?

The image you have on your switch does not support crypto, if you want to use ssh to access it you will need to load a crypto image on it.

I have downloaded this: 1518  Mar 01 1993 00:40:55 +00:00  c2950-i6k2l2q4-mz.121-22.EA14.bin.

It looks like it is far smaller than the original 3132319  Mar 01 1993 00:02:42 +00:00  c2950-i6q4l2-mz.121-22.EA14.bin,

 

Now switch's flash shows:  2  -rwx     3132319  Mar 01 1993 00:02:42 +00:00  c2950-i6q4l2-mz.121-22.EA14.bin

When I was trying to boot from the new IOS version I went into great problems bring the switch back to it's function. I would appreciate any assistance on how to install the crypto image.

Kindest Regards.

 

What does that mean, great problems?

could u pls. Paste a show boot?

 

did u try to update it via "archive download-sw...."

 

 

Ok,here I go.

I've downloaded and installed the new " IOS (tm) C2950 Software (C2950-I6K2L2Q4-M), Version 12.1(22)EA14, RELEASE SOFTWARE (fc1)" to get the "ssh" option. Used TFTP.

I did the boot system flash pointing to the new IOS version.

switch: boot
Loading "flash:c2950-i6k2l2q4-mz.121-22.EA14.bin"...#######

It rebooted normally with the new IOS version, nevertheless I got the "switch:" prompt nevertheless I don't have the command "enable". I got stuck with "switch:"

Now all the commands I have available are as below:

switch: ?
           ? -- Present list of available commands
        boot -- Load and boot an executable image
         cat -- Concatenate (type) file(s)
        copy -- Copy a file
      delete -- Delete file(s)
         dir -- List files in directories
  flash_init -- Initialize flash filesystem(s)
      format -- Format a filesystem
        fsck -- Check filesystem consistency
        help -- Present list of available commands
 load_helper -- Load and initialize a helper image
      memory -- Present memory heap utilization information
       mkdir -- Create dir(s)
        more -- Concatenate (display) file(s)
      rename -- Rename a file
       reset -- Reset the system
       rmdir -- Delete empty dir(s)
         set -- Set or display environment variables
   set_param -- Set system parameters in flash
        trap -- Cause a software breakpoint to occur
        type -- Concatenate (type) file(s)
 -- MORE --
       unset -- Unset one or more environment variables
     version -- Display boot loader version
switch:

Please, any idea?

Post the entire bootup process. I want to see why you're always going to ROMmon. I am suspecting the IOS you've uploaded to the switch is corrupt.

Actually I had not followed the upgrade process correctly. Thank you.

Did u check the RN for compatibility and requirements?

It seems u need to recover the Switch IOS..I don't have much experience with the 2950 but u should be able to reload the old imag via tftp via ROMON mode (switch:)

I had lost my switch configuration and IOS, fortunately I had the image on my computer and was able to restore it using xmodem option. Now everything is working fine. Thank you all.
