Enabling and Configuring SNMP Monitoring
To configure SNMP to gather system status information for the appliance, use the

SNMP Traps
SNMP provides the ability to send traps, or notifications, to advise an administration application when one
or more conditions have been met. Traps are network packets that contain data relating to a component of
the system sending the trap. Traps are generated when a condition has been met on the SNMP agent (in this
case, the Cisco Web Security Appliance appliance). After the condition has been met, the SNMP agent
then forms an SNMP packet and sends it to the host running the SNMP management console software.
