The ONS 15310-MA SDH use SNMP traps to generate all alarms and events, such as raises and clears.
The traps contain the following information:

the slot or port, synchronous transport signal (VC high-order path), and Virtual Tributary (VC
low-order path).
• Severity of the alarm (critical, major, minor, or event) and service effect (service-affecting or
non-service-affecting).
• Date and time stamp when the alarm occurred.
12.6.1 Generic and IETF Traps
The ONS 15310-MA SDH support the generic and IETF traps listed in Table 12-4.
