of SNMPv2p and SNMPv2u. (It is
also called SNMPv2star.) The
documents defing this version were
never published as RFCs.
SNMPv3 (proposed): This version of
the protocol is a combination of
user-based security and the protocol
operations and data types from
SNMPv2p and support for proxies.
The security is based on that found
in SNMPv2u and SNMPv2*, and
updated after much review. The
documents defing this protocol will
soon be published as RFCs.

Trivial File Transfer Protocol.
TFTP is a simple form of the File
Transfer Protocol (FTP). TFTP uses
the User Datagram Protocol (UDP, a
direct protocol used to communicate
datagrams over a network with little
error recovery) and provides no
security features. It is often used by
servers to boot diskless
workstations, X-terminals, and
routers.
Trunking. The process of combing
a set of trunks that are traffic-
engineered as a unit for the
establishment of connections
between switching systems in which
all of the communications paths are
interchangeable.

Machine.
UPMA. The first of two UPMs in
Motorola's MPC855T processor.
