Upgrading Procedure
Trivial File Transfer Protocol (TFTP), a protocol in the TCP/IP protocol suite, is used to transfer trivial files
between clients and the server. It provides not-so-complex and low-cost file transfer services. TFTP
provides unreliable data transfer services over UDP and does not provide any access authorization and
authentication mechanism. It employs timeout and retransmission to guarantee the successful delivery of
data. The TFTP software is much smaller than the FTP software in size:
File Transfer Protocol (FTP) is an application-layer protocol in the TCP/IP protocol suite. It mainly transfers
files among remote hosts. Over TCP, FTP provides reliable and connection-oriented data transfer service
but does not provide access authorization and authentication mechanism.
Step1
Set up an upgrade environment.

Set up a TFTP/FTP upgrade environment
Connect Ethernet 0/0 to a PC with a crossover cable. Start the TFTP/FTP program on the PC, and set the
path of TFTP/FTP server to directory of the application program. You need to set username and password
if FTP server is used.
