MIBs Overview

This chapterprovides information about Management Information Base (MIBs)supported in Dell Networking W- Series Instant 6.4.0.2-4.1 software release.

MIBs

A MIB is a virtual database that contains information used fornetwork management. Each managed device contains MIBs that define its properties. A separate MIB is provided foreach defined property, such as the group of physical ports assigned to a VLAN orthe statistical data of packets transferred at a specific rate.

MIB objects, such as a MIB table ora specific object in a MIB table, are identified with Object identifiers (OIDs). The OIDs are designated by text strings and integersequences. Forexample, Dell and 1.3.6.1.4.1.674 both represent the private enterprise node Dell.

Figure 1 illustrates the high-level hierarchy of the Enterprise MIBs.

Figure 1 High-Level MIB Hierarchy

The hardware MIBs are assigned underthe Dell organization code, while all otherMIBs are underthe Aruba organization code.

MIBsOverview | 22

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

Table 4: MIB Node Identification - Enterprise Nodes

		Name
1	1	OSI

3	1.3	ORG

6	1.3.6	DOD

1	1.3.6.1	Internet

4	1.3.6.1.4	Private

1	1.3.6.1.4.1	Enterprise

674	1.3.6.1.4.1.674	Dell

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. Forinformation about reading MIB text files, see Reading MIB Files on page 26.

SNMP

MIB objects can be accessed through the Simple Network Management Protocol (SNMP). To deliverinformation 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 forSNMP managers and SNMP agents to exchange.

The significant elements of SNMP are Managers, Agents, and MIBs:

•SNMP Managers (software application)are used forcommunicating and managing the devices that support SNMP Agents. SNMP Managers can also be used forsending configuration updates orcontrolling 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 othernetwork components.

•MIBs are used forcommunication 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. Forinformation on configuring SNMP through the Instant UI, see Dell Networking W-Series Instant Access Point 6.4.0.2-4.1 UserGuide.

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

•The OID of the MIB object

Table 5: 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-	Defines the object accessibility:
Access	• 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 userin locating desired OID values formonitoring.

It is assumed that the workstation is connected to the Instant and a MIB browseris available. Formost 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:

•snmpget -v1 -c <community name> <Instant IP address> <MIB OID/MIB name>

•snmpget -v2c -c <community name> <Instant IP address> <MIB OID/ MIB name>

•snmpget -v3 -c <community name> <Instant IP address> <MIB OID/ MIB name>

The MIB objects can also be viewed from a MIB BrowserGUI.

Reporting WLAN Health

SNMP MIBs are frequently used forrunning health checks on Dell Networking W-Series Instant devices, through a MIB browserapplication.

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 Controllerand 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 userin locating desired OID values for monitoring. Formost 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 controlleraddress is configured on management station, the following MIBs are specific to a particularW-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 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.

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. Formore 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 compilerof the SNMP manager. A word processorortext editorcan be used to open the ASCII file. The contents of an example Dell enterprise MIB file are as follows:

Opening Line

Following is the opening line, the beginning of the MIB file.

The Imports section lists the objects that are defined in external ASN.1 files and are used in the current MIB file.

Inheritance

This section shows the vendorof the MIB and the inheritance, and provides an overall description.

A significant part of inheritance is the OID. The entire OID is not listed foreach 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 theirrelated OIDs are listed in the snmp file. Formore 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 globalobject ortable. 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 ControllerTransport 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.

{ "iso",	HASHNEXT("1") },

{ "org",	HASHNEXT("1.3") },

{ "dod",	HASHNEXT("1.3.6") },

{ "internet",	HASHNEXT("1.3.6.1") },
