SNMP reference
This appendix describes the Simple Network Management Protocol (SNMP) capabilities that Dell EMC storage systems support.
This includes standard MIB-II, the FibreAlliance SNMP Management Information Base (MIB) version 2.2 objects, and enterprise
traps.
The storage systems can report their status through SNMP. SNMP provides basic discovery using MIB-II, more detailed status
with the FA MIB 2.2, and asynchronous notification using enterprise traps.
SNMP is a widely used network monitoring and control protocol. It is an application layer protocol that facilitates the exchange
of management information between network devices. It is part of the Transmission Control Protocol/Internet Protocol
(TCP/IP) protocol suite.
SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network
growth. Data is passed from SNMP agents reporting activity on each network device to the workstation console used to
oversee the network. The agents return information contained in a Management Information Base (MIB), which is a data
structure that defines what is obtainable from the device and what can be controlled (turned on and off, etc.).
Supported SNMP versions
The storage systems allow use of SNMPv2c or SNMPv3. SNMPv2c uses a community-based security scheme. For improved
security, SNMPv3 provides authentication of the network management system that is accessing the storage system, and
encryption of the information transferred between the storage system and the network management system.
When SNMPv3 is disabled, SNMPv2c will be active. When SNMPv3 is enabled, SNMPv2c will only have access to the MIB-II
common system information. This allows device discovery.
Whether you use SNMPv2c or v3, note that the only SNMP-writable information is the system contact, name, and location.
System data, configuration, and state cannot be changed via SNMP.
Standard MIB-II behavior
MIB-II is implemented to support basic discovery and status.
An SNMP object identifier (OID) is a number assigned to devices in a network for identification purposes. OID numbering is
hierarchical. Using the IETF notation of digits and dots resembling very long IP addresses, various registries such as ANSI assign
high-level numbers to vendors and organizations. They, in turn, append digits to the number to identify individual devices or
software processes.
The system object identifier (sysObjectID) for Dell EMC storage systems is 1.3.6.1.4.1.674. System uptime is an offset from
the first time this object is read.
In the system group, all objects can be read. The contact, name, and location objects can be set.
In the interfaces group, an internal PPP interface is documented, but it is not reachable from external to the device.
The address translation (at) and external gateway protocol (egp) groups are not supported.
