SNMP Three significant elements of SNMP are Managers, Agents, and MIBs.  Managers (software application) are consoles that are used to communicate with and manage devices that support SNMP Agents. Managers collect information by polling Agents. Managers can also be used to send configuration updates or send controlling requests to actively manage a network device.  Agents (software application) provide information from the network devices to the Managers. Network devices include workstations, routers, microwave radios, and other network components. Agents are embedded in the Dell PowerConnect W-Series Mobility Controllers firmware, unlike some devices such as servers that require the agent to be installed separately.  MIBs are used for communication between the Managers and the Agents. The OIDs of the MIBs enable the Managers and Agents to communicate specific data requests and data returns.  To ensure functionality with SNMP, MIB objects must be defined with the proper keywords, as shown in Table 4.

SNMP
Three significant elements of SNMP are Managers, Agents, and MIBs.
Managers (software application) are consoles that are used to communicate with and manage devices that
support SNMP Agents. Managers collect information by polling Agents. Managers can also be used to send
configuration updates or send controlling requests to actively manage a network device.
Agents (software application) provide information from the network devices to the Managers. Network
devices include workstations, routers, microwave radios, and other network components. Agents are
embedded in the Dell PowerConnect W-Series Mobility Controllers firmware, unlike some devices such as
servers that require the agent to be installed separately.
MIBs are used for communication between the Managers and the Agents. The OIDs of the MIBs enable the
Managers and Agents to communicate specific data requests and data returns.
To ensure functionality with SNMP, MIB objects must be defined with the proper
keywords
, as shown in
Table 4
.
ArubaOS Enterprise MIBs support SNMPv1, SNMPv2, and SNMPv3.
Table 4
MIB Keywords
Keyword
Description
Sequence
The sequence of objects of the MIB. This keyword is used mostly with entry MIB objects
to list the MIB objects that exchange information.
Syntax
Textual conventions, such as
Integer32
.
Max-Access
Defines the object accessibility:
read-only
: can be retrieved but not modified
read-write:
can be retrieved and modified
not-accessible
: cannot be retrieved; it is for internal (device) use only
accessible-for-notify
: can be retrieved when a trap message (notification) is sent
Status
Defines the status of the object:
current
: up to date and valid.
deprecated
.: indicates an obsolete definition. It permits new or continued
implementation to maintain interoperability with existing implementations.
obsolete
: obsolete. It should not be implemented and/or can be removed if previously
implemented.
Description
A text string that describes the object.
