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.

security features. It is often used by
servers to boot diskless
workstations, X-terminals, and
routers.

a set of trunks that are traffic-
