Hello mtchicmen

Hello mtchicmen

As in your output there are two files available in the flash memory i.e. "config.text" and "private-config.text" and there is no such file having an extension of .bin that is the file of IOS. So you have to install the IOS in your switch. You can follow the below process to install IOS in the switch. For installing IOS you can use Hyper Terminal or Tera Term.

First of all increase the console speed by using the command:

switch: set BAUD 115200

Then open the hyper terminal session by setting speed of 115200 instead of 9600.

Then you will get the switch: prompt.

switch: flash_init

switch: load_helper

switch: copy xmodem: flash:c2955-i6q4l2-mz.121-13.EA1.bin

Then click on transfer---- click on send file--- give the file path and select xmodem --- click on send. It will start copying the files from pc to switch. Then after copying it will automatically install IOS into the switch. When installing will complete you have to type "boot" command and you will get the access of switch.

Hello mtchicmen

You have to contact with Cisco to purchase the IOS.

First of all you have to check which features do you require. Then you can check in Cisco Feature Navigator in which IOS image these features are available. Then you can purchase that IOS from Cisco.

Hello mtchicmen

"Xmodem" is a simple file transfer protocol that is used to transfer files. It is used to transfer the IOS files from pc to the router/switch. When we don't have TFTP server then we can use xmodem but pc must be directly connected to the router's console.
