Cisco iOS

Ø  Cisco iOS Use IFS (Integrated file System) To keep track of files and Folders
Ø  IFS give us Differnet Places where we Store and Retrive the Files 

Load the iOS from TFTP Server to Router
First Check the Connectivity with TFTP Server
TFTP Server is nothing But a PC which we install the TFTP software to Copy the Files from the Router}
Ø  Router# ping 192.168.1.50 (tftp Server ip address)
Ø  Router# copy tftp: flash:
Ø  Address or name of remote host []? 192.168.1.50                               {tftp server ip address}
Ø  Source filename []? c2900-universalk9-mz.SPA.151-4.M4.bin           {iOS file name}
Ø  Destination filename [c2900-universalk9-mz.SPA.151-4.M4.bin]             {enter}
  {iOS file name same as above}

{This will take some time}

Ø  Router# show flash:                                      (to check the iOS}

To Boot from this iOS image
Ø  Router(config)#boot system flash c2900-universalk9-mz.SPA.151-4.M4.bin            {new iOS}
Ø  Router(config)#no boot system flash c2600-universalk9-mz.SPA.151-4.M4.bin  
{To Train the router to Boot the system with newly iOS instead of Previous}
