Configuring SNMP Alerts
Simple network management protocol (SNMP) traps, or event traps, are
similar to email event alerts. They are used by a management station to
receive unsolicited data from the CMC.
You can configure the CMC to generate event traps. Table 11-1 provides an
overview of the events that trigger SNMP and email alerts. For information on
email alerts, see "Configuring Email Alerts" on page 291.
