HP UX 11i v2 Networking Software manual Snmp, 225

SM	The Subnet Manager (SM) configures and manages routers, switches, and channel adapters.
	Multiple subnet managers per subnet are supported.
SMP	Subnet Management Packet (SMP) on the fabric.
SNMP	Simple Network Management Protocol (SMNP) lets a user define management information
	base (MIB) extensions. SNMP agents access MIB objects when requested by an SNMP Manager.
Target Channel	The Target Channel Adapter (TCA) is the complement to HCA. It is the end node component
Adapter	of an I/O device that connects it to the fabric.
TCA	See Target Channel Adapter (TCA).
TCP	Transmission Control Protocol (TCP).
TFTP	Trivial File Transfer Protocol (TFTP) is a simplified version of FTP that allows files to be
	transferred from one computer to another over a network, usually without the use of client
	authentication (for example, username and password).
Traps	Unsolicted reports sent by SNMP agents to interested clients. Trap messages are used to report
	significant TCP/IP events asynchronously.
UDP	An Internet protocol that provides connectionless datagram delivery service to applications.
	UDP over IP adds the ability to address multiple endpoints to IP within a single network node.
Unicast	Analogous to PPP, unicast is a communication link between a one sender and one receiver.
	Unlike multicast, unicast is the serial transmission of data between a sender and receiver.
Upper Layer	Any protocol residing in OSI Layers five or above. Standard ULPs supported by InfiniBand
Protocol (ULP)	include Internet Protocol (IPoIB) and Message Passing Interface (MPI).
VLAN	Virtual LAN. Unlike conventional LANs, a VLAN uses methods other than geographic location
	to map workstations. This allows the administrator to more easily manage load-balancing,
	band-width allocation, and add new users.
