Simple Network Management Protocol
(SNMP)
The Simple Network Management Protocol (SNMP) is designed to manage devices on IP networks by monitoring device
operation, which might require administrator intervention.
NOTE: On Dell Networking routers, standard and private SNMP management information bases (MIBs) are supported,
including all Get and a limited number of Set operations (such as set vlan and copy cmd).

Protocol Overview
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.
