SNMP Trap Types
The SNMP agent generates traps to notify the administrator of events such as
configuration changes, component failures, and disconnection of Access Points.
Administrators can configure the Agent and the Controller, defining the level of trap to
receive. The following trap types are supported by ExtremeWireless Controllers:
- Interfaces MIB (IF-MIB) linkDown (.1.3.6.1.6.3.1.1.5.3)
- Interfaces MIB (IF-MIB) linkUp (.1.3.6.1.6.3.1.1.5.4)
- HIPATH-WIRELESS-HWC-MIB apTunnelAlarm (.1.3.6.1.4.1.4329.15.3.19.4)
- Sent by the controller when it detects that it has lost the connection to an AP. The
trap identifies the AP that the controller can no longer contact.
- HIPATH-WIRELESS-HWC-MIB hiPathWirelessLogAlarm (.1.3.6.1.4.1.4329.15.3.9.6)
- A generic trap that contains specific information relevant to the event. The
information is carried in the trap, and the information varies from event to
event.
- The trap contains the trap severity, the component on the controller that raised the
event, and the text string associated with the event, as it appears in the controller
GUI.
- A trap containing one event that also is displayed in the controller‘s Event / Log
report page. The trap is sent when the event is raised and recorded on the
controller.
- This trap accounts for the vast majority of traps messages sent by the controller at
most sites.
