Interface Alarms
Table 18-3 provides information on traps that result in alarms raised against interface objects.
Syslog Traps
Note Care should be taken when using the Syslog alarm feature since there are multiple possible severity
levels that can be activated which can result in large trap volumes. This can affect Cisco 12000/10720
Router Manager performance (for example, when opening an Event Browser) and hinder effective
monitoring because of the high numbers of alarms that will be raised. It is advised that only the high
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 categories of Cisco EMF alarm severity. Syslog specific 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:
