Simple Network Management Protocol
(SNMP)
Simple network management protocol (SNMP) is supported on Dell Networking OS.
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.
Implementation Information
The following describes SNMP implementation information.
● Dell Networking OS supports SNMP version 1 as defined by RFC 1155, 1157, and 1212, SNMP version 2c as defined by RFC
1901, and SNMP version 3 as defined by RFC 2571.
● Dell Networking OS supports up to 16 trap receivers.
● Dell Networking OS implementation of the sFlow MIB supports sFlow configuration via SNMP sets.
