Traps are SNMP base messages used by SNMP elements to report changes in status or alarm
conditions to remote SNMP management entities. Traps are generally used to alert network
administrators of potential equipment problems or other noteworthy events. Two types of
information are conveyed in the trap mechanism: Events and Alarms. Events Traps are sent
every time the monitored event occurs. Events have only one state. Alarms are events having
two states, Active and Clear. When the alarm condition is first detected, an alarm active trap
is emitted. Alarms are considered active until the condition cleared and the alarm clear trap is
emitted.
Note VBrick supports SNMPv3 in addition to SNMP v1/v2. SNMP v3 is a "Secure SNMP
implementation" as defined in Section 11.3 of RFC 3414. It provides initial
configuration in accordance with Appendix A.1 of RFC 3414 and also implements the
Privacy Protocol (DES Encryption) as described in RFC 3414.

The IP Addresses of SNMP management stations to which traps
are to be sent. The SNMP management application should be
active on these stations in order to receive a number of SNMP
Traps, which are supported by the VBrick. Enterprise-specific
traps listed in order of trap identification number are shown in
Table 4.
