Introduction

 

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.

 

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

 

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.
