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 identiers 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.

The Dell Networking OS supports SNMP version 1 as dened by RFC 1155, 1157, and 1212, SNMP version 2c as dened by RFC 1901.
Conguring the Simple Network Management
Protocol
NOTE
: The congurations in this chapter use a UNIX environment with net-snmp version 5.4. This is only one of many RFC-
compliant SNMP utilities you can use to manage the Aggregator using SNMP. Also, these congurations use SNMP version 2c.
Conguring SNMP version 1 or version 2 requires only a single step:
1 Create a community.
