Exceptional condition notification sent by SNMP.

In the context of SNMP, an unsolicited message sent by an agent to a management station. The purpose is to notify the management station of some unusual event.

An alert, error, or system message from a server reporting an exception (for example, a device failure or a threshold violation) in a server.

a program interrupt mechanism that automatically updates the state of the network to remote network management hosts. The SNMP agent on the switch supports these SNMP traps.

An old term rather loosely used to designate various dark-colored, heavy igneous rocks, including especially the feldspathic-augitic rocks, basalt, dolerite, amygdaloid, etc., but including also some kinds of diorite. Called also trap rock.

A common name for dark, fine grained igneous rock, especially basalt and diabase.

In a multiple block image, the slight overlap between colors that prevents white lines from appearing on the print.

The removal of small gaps in ink coverage between two or more adjacent, colored objects. When two objects of different color are butted against each other, a small white or other color gap can sometimes appear if the films and plates are in perfect register. To avoid these gaps, an overlap between the objects is sometimes created. The color of the overlap is selected to minimize the visual effect of the overlap, and yet fill the Trap space as necessary.

The overlapping of ink where one color meets another to prevent paper from showing through.

The ability of a printed ink film to properly accept a succeeding ink film (e.g., the ability of a first-down cyan ink to accept or "trap" a film of yellow ink to produce a green).

An exception caused by an A-line instruction.

The suspension of a thread from its normal sequence of execution to handle an exception.

A change in system state that is caused by an exception and that may be detected by the executing program that took the exception. Traps are hardware features that may be enabled or disabled. If traps are enabled, they can change the flow of control in the program that took the exception. In response to a trap, the system may generate a signal (for example, SIGFPE), which the program can detect. Such a program can be designed to handle traps. HP Fortran 90 provides the ON statement to handle traps.

A change in a program's flow of control due to the occurrence of an exception condition.

A wooden instrument shaped somewhat like a shoe, used in the game of trapball. It consists of a pivoted arm on one end of which is placed the ball to be thrown into the air by striking the other end. Also, a machine for throwing into the air glass balls, clay pigeons, etc., to be shot at.

A clay target throwing device.

The tactic of offering the apparent capture of a hanging piece or pawn to get your opponent to make a mistake in his position.

Luring a defender into an area and slamming him out of the play; a prenuptial agreement.

A hidden method of luring the opponent into making an error. The lure or bait must be just enough to entice, without making the opponent suspicious - pawns are usually used. Traps should only be laid if they fit into an overall strategy, so even if the trap fails your position is improved or at least maintained. Always assume an opponent will see the trap: simply playing for traps is bad strategy.

A situation where a superficially tempting move is left available for an unwary opponent. If he takes the bait it usually results in an advantage - even a win - for the player who set the trap.

Fishing by means of devices such as cages that trap fish in a confined environment. Traps are often designed and baited to catch a particular species, as in a crab pot, lobster pot, tuna trap, and fyke net. There is little to no bycatch associated with traps.

A machine or contrivance that shuts suddenly, as with a spring, used for taking game or other animals; as, a trap for foxes.

To catch in a trap or traps; as, to trap foxes.

A device used for catching and holding animals.

Fig.: A snare; an ambush; a stratagem; any device by which one may be caught unawares.

Fig.: To insnare; to take by stratagem; to entrap.

Money is trapped in the pot if it faces the imminent danger of becoming dead money. Typically you're trapped if after putting some money in the pot you're faced with the proposition of calling a raise in order to continue, especially an uncomfortably large raise. A player is also said to be trapped if caught calling (e.g. on a draw) between two other players who keep raising and re-raising each other.

a device in which something (usually an animal) can be caught and penned

An opening in the stage floor. A trap can be used for all kinds of things. The Rep’s stage is fully “trapped” but in fact this facility is rarely used.

A star trap is a set of triangular sprung flaps in the stage floor through which an actor can be propelled from a lift below stage. The Vampire Trap was invented for James Planche's 1820 adaption of Polidori's The Vampyr. It involved two spring leaves that parted under pressure and immediately reclosed. Placed in the floor or stage wall, it could give the impression a figure was passing through solid matter. The Corsican Trap, made for Dion Boucicault's 1852 adaption of Alexandre Dumas' The Corsican Brothers, involved an ascending track, on which a wheeled cart could be run, rising up out of the stage through a 'bristle' trap - a trapdoor covered with bristles painted to match the scenery. Once on the stage and in view, the track was covered by a sliding arrangement reminiscent of that of a roll- top desk; towhit, nothing was seen except the ghost rising up through the floor and gliding across the stage.
