Configuring SNMP Alerts
Simple network management protocol (SNMP) traps, or event traps, are
similar to e-mail 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 e-mail alerts. For information
on e-mail alerts, see "Configuring E-mail Alerts" on page 303.
