Simple Network Management Protocol (SNMP)
Simple network management protocol (SNMP) is supported on the MXL switch platform.
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 identiers to address managed objects, but managed objects also have a textual
name called an object descriptor.
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).
Implementation Information
The following describes SNMP implementation information.
• The Dell Networking OS supports SNMP version 1 as dened by RFC 1155, 1157, and 1212, SNMP version 2c as dened by RFC
1901, and SNMP version 3 as dened by RFC 2571.
• The Dell Networking OS supports up to 16 trap receivers.
• The Dell Networking OS implementation of the sFlow MIB supports sFlow conguration via SNMP sets.
• SNMP traps for the spanning tree protocol (STP) and multiple spanning tree protocol (MSTP) state changes are based on
BRIDGE MIB (RFC 1483) for STP and IEEE 802.1 draft ruzin-mstp-mib-02 for MSTP.
• All objects in the LLDP-EXT-DOT1-DCBX-MIB and IEEE8021-PFC-MIB tables are read-only.
• In the LLDP-EXT-DOT1-DCBX-MIB, lldpXdot1dcbxRemoteData tables are not supported.
Conguration Task List for SNMP
Conguring SNMP version 1 or version 2 requires a single step.
NOTE: The congurations in this chapter use a UNIX environment with net-snmp version 5.4. This environment is only
one of many RFC-compliant SNMP utilities you can use to manage your Dell Networking system using SNMP. Also, these
congurations use SNMP version 2c.
• Creating a Community
Conguring SNMP version 3 requires conguring SNMP users in one of three methods. Refer to Setting Up User-Based Security
(SNMPv3).
