SNMP Traps
SNMP traps are network-management notifications of an event occurring at a
managed network node. These events can identify problems in the network,
machines up or down, and so on. These servers use traps to signal conditions related
to the server’s health, including critical conditions related to physical components,
the return to a normal state for these components, and other situations related to the
state of the software running on the SP (for example, network settings being
reconfigured).
Traps are defined in the MIB files and are generated, received, and processed by an
SNMP management station. SNMP trap data is uniquely identified by the MIB. Each
SNMP trap contains information identifying the server's name, IP address, and other
relevant data about the event.
Within the server event MIB, each trap has the following variables and event
bindings; see
TABLE 3-1.
