Simple Network Management Protocol (SNMP)

Network management stations use SNMP to retrieve or alter management data from network elements. A datum of management

information is called a managed object; the value of a managed object can be static or variable. Network elements store managed objects

in a database called a management information base (MIB).

MIBs are hierarchically structured and use object identifiers to address managed objects, but managed objects also have a textual name

called an object descriptor.

NOTE: An I/O Aggregator supports standard and private SNMP MIBs, including Get operations in supported MIBs.

NOTE: The system does not support SNMPv3 traps in PMUX mode.
