Cisco CCNA Exam Tutorial: Using Trivial File Transfer Protocol (FTP)

Among the first things you do when you get started studying for your CCNA examination is memorizing a list of interface numbers as well as the protocols which operate on these ports. If you are a seasoned networker, you understand the majority of the protocols which are cited – DNS, DHCP, FTP, SMTP, and so forth. But there is 1 protocol which you may not have experience with, but is really essential for CCNA test success and achievement in coping with Cisco routers and switches, and that is TFTP – Trivial File Transfer Protocol.

TFTP is essentially FTP’s non-secure comparative. There are no passwords, no authentication plot, nothing! As somebody once explained, “If I am transferring my documents, there is nothing ‘insignificant’ about it.”

Great. So you are thinking, “What the hell do we use TFTP for, anyhow?”

TFTP is used in the Cisco globe to execute IOS updates and also to save configs into a TFTP Server. Cisco routers may serve as TFTP servers, or you may use a workstation to fulfill that function.

In the event that you had to replicate an IOS image to a router, as an instance, you can do this easily by simply linking your PC to the router’s console interface (via a metering cable, right?) . Your PC would have to conduct TFTP server program. There are a number of free TFTP server applications programs that work very nicely – simply enter “freetftp host” to Google or your favorite search engine and you will see exactly what I mean.

Using TFTP in this manner is a superb way to have backup copies of IOS router or images configs directly in your own notebook. And take it away from me, once the day comes that you want these copies, you will be happy you did!

When doing this type of backup, you will want to name the document you are copying, in addition to the IP address of this device you are copying to.

Using TFTP to execute IOS updates takes a bit getting used to, particularly the syntax of this backup control. But understanding that syntax and how to use TFTP will really get one step nearer to the CCNA!
