How to load a save configuration file through Cisco TFTP Server

1.1 Experimental purposes:

Learn to use TFTP Server.

1.2 Experimental contents

• Understand the meaning of TFTP server;

L Learn how to use TFTP server to save configuration files such as Flash and startup-config on the router;

L Learn how to load a saved configuration file via a TFTP server;

1.3 Experiment Steps:

Follow the instructions below to connect the network device

1, first we need to have a TFTP server running in our network;

2. Once we have a TFTP server enabled, we need to ping the router to make sure that the TFTP server arrives and, of course, to record the address of your TFTP server. For example, here we use 192.168.1.25 as our TFTP server address, if the ping of this address is not a problem, you can directly use copy flash TFTP, but if there is a problem, you must first solve the problem and then use copy Flash TFTP command;

3, we should also check the local router on the size of our flash and its iOS operating system file name, you can use the command show flash to view;

4, Router#copy Flash TFTP

IP address or name of remote host[255.255.255.255]?

Here is what you ask for the address of the server where you want to store your flash we enter 192.168.1.25 then press ENTER;

(1) filename to write on the TFTP host?

Here is a question about how to save the Flash file at your destination. We can enter the Lab_b.ios on this;

(2) then you will see:

Writing Lab_b.ios!!!!!!!!!!!! ...... !!!!!!!!!!!!!!!!!!!

5926652 bytes copied in 82.712 secs (71654 bytes/sec)

The above information shows that your save has been successfully completed, copy Flash TFTP has been successfully completed, once the Copy command is completed, the router will tell us, copying the past files occupy the TFTP server how much space, total time consuming;

(3) Then we'll learn how to load iOS backup files that are stored in a TFTP server:

(4) First of all we have to confirm that the TFTP server can be reached, and secondly we will use the show Flash command to confirm that our routers have enough space to load the new iOS software, and finally to the remote server to check our new iOS file is what, Since we are in the experimental environment, so we just have a simple look at it, our file name is Lab_b.ios;

(5) If there is no problem, you can enter:

Router#copy TFTP Flash

Enter 192.168.1.25 under IP address or name of remote host[255.255.255.255];

In name of TFTP filename to copy into flash[]?

Input Lab_b.ios

In the copy Lab_b.ios from 192.168.1.25 into flash memory? [Confirm] Press ENTER later on, if there is no problem, load the work of Flash will be completed.
