SNMP Traps and Informs

An SNMP agent sends notifications in the form of traps or informs to identify important system events.
Traps do not receive acknowledgments from the destination whereas informs do receive
acknowledgments.
Cisco Unity Connection does not support SNMP traps.
Note
For all notifications, the system sends traps immediately if the corresponding trap flags are enabled. In
the case of the syslog agent, the Cisco Unified CM alarms and system-level log messages get sent to
syslog daemon for logging. Also, some standard third-party applications send the log messages to syslog
daemon for logging. These log messages get logged locally in the syslog files and also get converted into
SNMP traps/notifications.
The following list contains Cisco Unified CM SNMP trap and inform messages that are sent to a
configured trap destination:

SNMP Trace Configuration

For Cisco Unified CM, you can configure traces for the SNMP agent in the Trace Configuration window
in Cisco Unified Serviceability by choosing the Cisco Unified CM SNMP Service in the Performance
and Monitoring Services service group. A default setting exists for all the agents. For Cisco CDP Agent
and Cisco Syslog Agent, you use the command line interface (CLI) to change trace settings, as described
in the Command Line Interface Reference Guide for Cisco Unified Solutions.
