Chapter 1
MIBs Overview
This guide provides information about Management Information Base (MIBs) supported in Dell Networking
W-Series Instant Access Point 6.2.1.0-3.3.0.0. This document is intended for network administrators and
operational personnel responsible for managing the Dell Networking W-Series Instant Access Point APs (WIAPs).
MIBs
A MIB is a virtual database that contains information used for network management. Each managed device
contains MIBs that define its properties. A separate MIB is provided for each defined property, such as the
group of physical ports assigned to a VLAN or the statistical data of packets transferred at a specific rate.
MIB objects, such as a MIB table or a specific object in a MIB table, are identified with Object identifiers
(OIDs). The OIDs are designated by text strings and integer sequences.
The hardware MIBs are assigned under the Dell organization code, while all others are under the Aruba
organization code. For example, Aruba and 1.3.6.1.4.1.14823 both represent the private enterprise node
Aruba. Aruba is the parent of the proprietary MIBs that are supported on Dell W-Instant. Figure 1 illustrates
the high-level hierarchy of the Enterprise MIBs.

Table 5 indicates the numerical string that lists the nodes of the enterprise MIB hierarchy. The hardware
MIBs are assigned under the Aruba organization code, while all others are under the Aruba organization
code.

The information provided by a MIB is a file that describes network elements with numerical strings. This
information is compiled into readable text by the SNMP manager. For information about reading MIB text
files, see “Reading MIB Files” on page23.
SNMP
MIB objects can be accessed through the Simple Network Management Protocol (SNMP). To deliver
information between devices, every object referenced in an SNMP message must be listed in the MIB. A
component of a device that is not described in a MIB cannot be recognized by SNMP as there is no
information for SNMP managers and SNMP agents to exchange.
The significant elements of SNMP are Managers, Agents, and MIBs:
SNMP Managers (software application) are used for communicating and managing the devices that
support SNMP Agents. SNMP Managers can also be used for sending configuration updates or
controlling requests to manage a network device.
SNMP Agents (software application) provide information from the network devices to the SNMP
Managers. Network devices include workstations, routers, microwave radios, and other network
components.
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.
Dell Networking W-Series Instant Access Point MIBs support SNMPv1, SNMPv2, and SNMPv3. For information
on configuring SNMP through the Instant UI, see Dell Networking W-Series Instant Access Point 6.2.1.0-3.3.0.0
6.2.1.0-3.3.0.0 User Guide.
To retrieve information from a MIB, the following information is required:
SNMP version
SNMP community name—public or private
18 | MIBs Overview Dell Networking W-Series Instant Access Point 6.2.1.0-3.3.0.0 | MIB Reference Guide
The IP Address of the virtual controller
The OID of the MIB object
Table 6 MIB Keywords
Keyword Description
Sequence Refers to the sequence of objects of the MIB. This keyword is used with entry
MIB objects to list the MIB objects that exchange information.
Syntax Textual conventions, for example, 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: Indicates that the object status is 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.
In addition, MIB files can be placed in the appropriate disk location to assist the user in locating desired
OID values for monitoring.
It is assumed that the workstation is connected to the Instant and a MIB browser is available. For most
applications, the root of the MIB must be included in the OID—the OID begins with a decimal point as
shown below.
.1.3.6.1.4.1.674.2.2.1.1.2.1
If you are using an application that is run through the Linux shell, the command will be as follows:
snmpget -v 2c -c <community name> <Instant IP address> <MIB OID>
The MIB objects can also be viewed from a MIB Browser GUI.

For assistance to set up an account and access files, contact customer service. See “Contacting Support” on
page15.
Reporting WLAN Health
SNMP MIBs are frequently used for running health checks on Dell W-Instant devices, through a MIB
browser application.
To retrieve information from a MIB, the following information is required:
SNMP version
SNMP community name—public or private
The IP Address of the Virtual Controller and the slave W-IAPs
The OID of the MIB value you want to monitor
MIB files can be placed in the appropriate disk location to assist the user in locating desired OID values for
monitoring. For most applications, the root of the MIB must be included in the OID—the OID begins with a
decimal point as shown in the following example:
.1.3.6.1.4.1.674.2.2.1.1.2.1
SNMP Operations on W-IAPs
Although the virtual controller address is configured on management station, the following MIBs are
specific to a particular W-IAP and therefore cannot be accessed from the Virtual Controller.
ifTable
ifXTable
dot1qTpFdbTable
To enable the management station to access the IF-MIB and Q-BRIDGE-MIB tables and W-IAPs to send
traps, you must configure the IP address of each W-IAP on the management station. The management
station can automatically configure the W-IAP details, by obtaining the IP address of each W-IAP from the
Dell Networking W-Series Instant Access Point 6.2.1.0-3.3.0.0 | MIB Reference Guide Using MIBs | 21
AP MIB (aiAccessPointTable), which lists all the slave W-IAPs in a swarm and is implemented on a virtual
controller.
You do not have to set the SNMP community string and security parameters on each W-IAP as this
configuration is common to all W-IAPs and is inherited from virtual controller.
MIB Browsers
If you are using an application that is run through the Linux shell, the command would be as follows:
snmpget -v 2c -c <community name> <Instant IP address><MIB OID>
Figure 2 shows an example of submitting a command to obtain information.
Figure 2 Running the snmpget Command
Figure 3 shows how information may be obtained through a graphical user interface (GUI). The user
interface and the available features vary by application.

Reading MIB Files
This section describes how to interpret the basic components of a MIB file. To determine the OIDs, view the
file snmp.h. For more information, see “SNMP File” on page25.
MIB files describe a specific component of a network device. The files are numerical strings that are
converted to ASCII text by the compiler of the SNMP manager. A word processor or text editor can be used
to open the ASCII file. The contents of an example ArubaOS enterprise MIB file, aruba-cts.my, are as
follows.

MIB Modules
MIB objects can be placed in logical groups such as Group and Table. A group typically contains at least one
global-object or table. The table lists the MIB objects that contain the information exchanged.
The first object of a table is an Entry. The OIDs of the subsequent objects of this table are appended
increments of the Entry OID.
The keyword SEQUENCE lists the objects of the table that contain device information. Each subsequent
object (Informative MIB Object) inherits the OID of the Entry, and contains information sorted by the
Syntax, Access, Status, and Description keywords.
