In this section:

The SBC, like other Ribbon devices, uses SNMP traps to notify management applications of events. SNMP traps are the messages that notify a management client that an event has occurred on the SBC node. These traps are not displayed in EMA and can be viewed from RAMP or other SNMP manager configured as a trap target. In case of error scenario, a trap is initiated at the device and forwarded to RAMP or another SNMP manager for processing.

You can configure up to 32 trap targets on the SBC.

The supported configurable SNMP trap types are SNMP v1, v2, and v3.

The following command is executed in CLI to configure the SNMP traps:

% set oam snmp trapTarget myTarget ipAddress <ip address> state enabled

The traps are triggered under specific conditions. For detailed information about these traps, refer to the relevant Trap page using the links provided in the table below.
