Chapter 5
Configuring Simple Network Management Protocol (SNMP)
SNMP Overview
An agent can send an unsolicited message to the manager at any time if a
•
significant, predetermined event takes place on the agent. This message is
called a trap. For details on SNMP traps (and associated MIB objects)
supported by the CSS software, see the
"CSS SNMP Traps"
section.
When a trap condition occurs, the SNMP agent sends an SNMP trap message
to the device specified as the trap receiver or trap host. The SNMP
Administrator configures the trap host (usually the SNMP management
station) to perform the action needed when a trap is detected.
