outSegment—A label on an outgoing packet.

Simple Network Management Protocol—See SNMP.

SNMP—Simple Network Management Protocol. Management protocol used almost exclusively in 
TCP/IP networks. SNMP provides a means for monitoring and controlling network devices, and for 
managing configurations, statistics collection, performance, and security.

trap—Message sent by an SNMP agent to a network management station, console, or terminal, 
indicating that a significant event occurred. Traps are less reliable than notification requests, because the 
receiver does not send an acknowledgment when it receives a trap. The sender cannot determine if the 
trap was received.
