severity traps are monitored by default, switching on others if more information is required.
Cisco IOS can be configured to send Syslog traps to a designated server. There are eight levels of Syslog
information which are mapped into four ca te gories of Cisco EMF alar m sev er ity. Syslog specif ic data is
inserted into the Message portion of the Cisco EMF alarm. In all cases, alarms are raised against the
Chassis object. Table 18-5 summarizes the severity mapping between trap and alarm:
