11.3 SNMP Support

The ONS 15327 supports SNMPv1 and SNMPv2c traps and get requests. The SNMP MIBs in the ONS
15327 define alarms, traps, and status. Through SNMP, NMS applications can query a management
agent using a supported MIB. The functional entities include Ethernet switches and SONET
multiplexers. The ONS 15327 also supports set requests for the System Group in MIB-II and the
Statistics, History and Alarm groups in the Remote Monitoring (RMON) MIB.

11.4 SNMP MIBs

A MIB is a hierarchically-organized collection of information. Network management applications gain
access to MIBs and then the NMSs run SNMP queries on the MIB objects supported by the SNMP agent
to gather management information. MIBs consist of managed objects and are identified by object
identifiers.
The ONS 15327 SNMP agent communicates with an SNMP management application using SNMP
messages.
