SNMP Traps
VBrick supports SNMP v2 and SNMP v3 traps. SNMP traps are a subset of the SNMP
management component of the VBrick. Use of any element of the SNMP management
system requires use of an SNMP browser or SNMP manager application (not supplied). The
SNMP MIB, which formally defines the SNMP interface to the VBrick, is contained within
the install directory of the VBrick release or from the Downloads
page on the VBrick
website. The SNMP MIB is located in vbrickSystem.mib and the default installation
directory is:
Program Files\VBrick\VBrick 7000-8000-9000\download\ReleaseVx_x_xx
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.
Trap Destination (1–4) 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 3.
