Examples of events on the Summit WM Controller that generate an alarm message:
Reboot due to failure
●

●
Software upgrade failure on the Wireless AP
●

If SNMP is enabled on the Summit WM Controller, alarm conditions will trigger a trap in SNMP
(Simple Network Management Protocol). An SNMP trap is an event notification sent by the managed
agent (a network device) to the management system to identify the occurrence of conditions.

way.
