In this case, please reboot the router tovalidate the reset IP address.z Do not modify the device name of the router; otherwise, the system prompts "Boot device shouldnot be modified" and skips to the next configuration item.z Only FE0 port can be used in MSR 20 series, and GE0 port in MSR 30 and MSR 50 series.Upgrading Application Program Through Ethernet InterfaceTFTP (Trivial File Transfer Protocol) is a protocol of the TCP/IP suit that is used to transfer trivial filesbetween clients and the server. It provides not-so-complex and low-cost file transfer services. Carriedover UDP, TFTP provides unreliable data transfer services and does not provide access authorizationand authentication mechanism. It employs timeout retransmission to guarantee the successfultransferring of data. TFTP takes much smaller size than FTP.FTP (File Transfer Protocol) is an application layer protocol in the TCP/IP suit. It mainly transfers filesamong remote hosts. Carried over TCP, it provides reliable and connection-oriented data transferservice but does not provide access authorization and authentication mechanism.Step 1: Set up an upgrade environment.Figure 5-7 Set up TFTP/FTP upgrade environmentConnect Ethernet port 0/0 to a PC by using a crossover cable. Start TFTP/FTP program on the PC asthe server, and set the path of TFTP/FTP server to point to the address of application program. Youneed to set user name and password if FTP server is used.
