Configuring, Modifying, and Monitoring the Unit

SNMP Traps

Traps are notices that the switch sends to an SNMP manager indicating that a specific event has occurred, or that the condition of a unit has changed significantly. SNMP Traps are disabled by default.

NOTE: Trap messages do not provide an entirely reliable event notification mechanism; they can get dropped, and are not acknowledged or retransmitted once dropped.

When the Switch detects an extraordinary event, it generates a trap. A trap is a notification message that may be sent to predefine Network Management Stations. A trap event may be a reset (cold or warm), detection of an interface link status change, an SNMP authentication failure due to an incorrect community string, and so.

The SNMP trap commands let you manage whether or not the device issues an authentication trap to the list of selected SNMP Management Stations. The list has a maximum of five entries.

get-auth	shows the traps authentication mode
set-auth	modifies	the traps authentication			mode
get-traps	show destination stations		in the		trap list
add-trap	add a destination station		to	the	trap list
del-trap	delete a	destination station		from	the trap list
