Many parameters are described by existing MIB documents. The
meanings of those parameters are not always implemented exactly;
instead, the parameters are treated as best as can be correlated. In
addition to SNMP and TFTP, the switch 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 IP addresses have not been assigned
SNMP Primitives
The major software interface 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:
1.
All datagrams must obey SNMP format.
2.
All datagrams must be sent via UDP and IP. Thus, all datagrams will
have UDP and IP headers.
3.
Datagrams may be sent over 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.
4.
The NMS must rely on IP, rather than MAC addressing for all
datagrams.
5.
All datagrams from the switch are addressed to either an NMS or the
broadcast IP address.
