To 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 TFTP
services. (Typically, TFTP must be started from the same directory that
contains the files to be transferred.) TFTP must be told the IP address of the
remote host (the IP address of the FN100), and the file transfer mode (which
must 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 should
take approximately one minute.
The initial one minute waiting may be omitted and this second transfer may
be initiated immediately following the first transfer; however, that causes the
second transfer to take approximately two minutes, and creates a slightly
heavier network load during the file transfer.
1.8 ADDITIONAL INTERFACES
In addition to SNMP and TFTP, the FN100 employs the following protocols, as
part 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 used
when no IP addresses have been assigned to the FN100
.
NOTE
If the above TFTP sequence is abnormally terminated, there is
no cause for alarm, since the FN100 maintains a back-up set of
software, and the FN100 will not use the incomplete new
software.
