1.4 SNMP PRIMITIVES

The major software interface between the NMS and ATX consists of one simple
mechanism – the exchange of SNMP (Simple Network Management Protocol,
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
unit 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 the unit.

•

All datagrams from the unit 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.
