MIBs Overview
This chapter provides information about Management Information Base (MIBs) supported in Dell Networking WSeries Instant 6.4.0.2-4.1 software release.
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. For example,
private enterprise node
Figure 1 illustrates the high-level hierarchy of the Enterprise MIBs.

and 1.3.6.1.4.1.674 both represent the
The hardware MIBs are assigned under the Dell organization code, while all other MIBs are under the Aruba
organization code.

Table 4 indicates the numerical string that lists the nodes of the enterprise MIB hierarchy.

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

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:
l 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.
l 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.
l 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.
Instant MIBs support SNMPv1, SNMPv2, and SNMPv3. For information on configuring SNMP through the Instant
UI, see
Dell Networking W-Series Instant Access Point 6.4.0.2-4.1 User Guide
.
To retrieve information from a MIB, the following information is required:
l SNMP version
l SNMP community name—
l The IP Address of the virtual controller
l The OID of the MIB object

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,
MaxAccess
Defines the object accessibility:
l
read-only
l
read-write:
l
not-accessible
l
accessible-for-notify
: Can be retrieved but not modified
Can be retrieved and modified
: Cannot be retrieved; it is for internal (device) use only
: Can be retrieved when a trap message (notification) is sent
Integer32
.
Status Defines the status of the object:
l
current
: Indicates that the object status is up-to-date and valid.
l
deprecated
: Indicates an obsolete definition. It permits new or continued implementation
to maintain interoperability with existing implementations.
l
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, you can use the following commands shown as
examples:
l snmpget -v1 -c <community name> <Instant IP address> <MIB OID/MIB name>
l snmpget -v2c -c <community name> <Instant IP address> <MIB OID/ MIB name>
l snmpget -v3 -c <community name> <Instant IP address> <MIB OID/ MIB name>
The MIB objects can also be viewed from a MIB Browser GUI.

Reporting WLAN Health
SNMP MIBs are frequently used for running health checks on Dell Networking W-Series Instant devices, through a
MIB browser application.
To retrieve information from a MIB, the following information is required:
l SNMP version
l SNMP community name—
l The IP Address of the Virtual Controller and the slave W-IAPs
l 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
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.
l ifTable
l ifXTable
l dot1qTpFdbTable
publicorprivate
root
of the MIB must be included in the OID—the OID begins with a decimal
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 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.

The following is an example of snmpget command to obtain information.
Figure 2 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 page 29.

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 Dell enterprise MIB file are as follows:

Inheritance
This section shows the vendor of the MIB and the inheritance, and provides an overall description.
A significant part of inheritance is the OID. The entire OID is not listed for each MIB object—instead, the parent of the
object is shown. The OID can be determined from the parent object as follows.
aiEnterpriseMibModules is the parent object —its OID is 1.3.6.1.4.1.14823.2.3.3.
aiStateGroup OBJECT IDENTIFIER ::= { aiMIB 2 }, the OID is 1.3.6.1.4.1.14823.2.3.3.1.2.
aiVirtualControllerKey OBJECT-TYPE, the OID is 1.3.6.1.4.1.14823.2.3.3.1.1.1.0.
All MIBs and their related OIDs are listed in the snmp file. For more information, see SNMP File on page 29.

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.

SNMP File
The snmp.h file lists the OIDs of all MIBs. Following are sections from snmp.h that show the complete OID of each
of the Controller Transport Service (CTS) MIB elements. The list starts from the ancestral parent
iso
.
The SNMP file with all Dell MIBs is listed in Standard SNMP MIBs on page 49.
All Instant MIBs inherit their OIDs from the Dell MIB node. The following rows list the MIBs that precede CTS,
starting from
{ "iso", HASHNEXT("1") },
{ "org", HASHNEXT("1.3") },
{ "dod", HASHNEXT("1.3.6") },
{ "internet", HASHNEXT("1.3.6.1") },
