Introduction

 

The major software interface between the NMS and FN100 consists of one 
simple mechanism – the exchange of SNMP (

 

l, RFC 1157) datagrams over any available physical media. The 

following restrictions apply: 

•

All datagrams must obey SNMP format. 

•

All datagrams must be sent via UDP and IP. Thus, all datagrams will have 
UDP and IP headers. 

•

Datagrams may be sent over any of the following physical media:

-

Ethernet/802.3 LAN - the datagram must have an Ethernet MAC header, 
with an Ethernet frame type of IP; or, the datagram must be in 802.3 
format with IP-encapsulation as defined by RFC 1042. 

-

UART (out-of-band management port) - the datagram must have a PPP 
header, which indicates that the datagram contains an IP packet. (The 
FN100 automatically detects the presence of a PPP connection versus 
being connected to a non-intelligent terminal.) 

•

The NMS must rely on IP, rather than MAC addressing for all datagrams sent 
to a FN100. 

•

All datagrams from the FN100 are addressed to either an NMS or the 
broadcast IP address. 

Within the context of this document, the terms “datagram”, “packet”, and “PDU” 
are synonymous.
