Chapter 1: IntroductionPage 1-8Fast Network 100 MIB Reference GuideTo distribute the new software to the FN100, the TFTP procedure is as follows:1. Start TFTP on the NMS, or on any other device which can provide TFTPservices. (Typically, TFTP must be started from the same directory thatcontains the files to be transferred.) TFTP must be told the IP address of theremote host (the IP address of the FN100), and the file transfer mode (whichmust be “binary”).2. Tell TFTP to transfer (“put”) the first file, (dnld_hdr).3. Wait one minute.4. Tell TFTP to transfer the second file, (dnld_software). This transfer shouldtake approximately one minute.The initial one minute waiting may be omitted and this second transfer maybe initiated immediately following the first transfer; however, that causes thesecond transfer to take approximately two minutes, and creates a slightlyheavier network load during the file transfer.1.8 ADDITIONAL INTERFACESIn addition to SNMP and TFTP, the FN100 employs the following protocols, aspart of its software interface with an NMS:• UDP - User Datagram Protocol, RFC 768.• IP - Internet Protocol, RFC 791.• ARP - Ethernet Address Resolution Protocol, RFC 826.• RARP - Reverse Address Resolution Protocol, RFC 903. RARP is only usedwhen no IP addresses have been assigned to the FN100.NOTEIf the above TFTP sequence is abnormally terminated, there isno cause for alarm, since the FN100 maintains a back-up set ofsoftware, and the FN100 will not use the incomplete newsoftware.
