About this Guide This manual is for network administrators and operators responsible for managing the controller. NOTE: Beginning with this release, MIB module tables and OIDs are no longer documented in this guide. To view current MIB module tables and OIDs, download the standard mibs tar.gz file from download.dell-pcw.com and view each MIB using a free MIB browser. See section “MIB Browsers” on page 13 for viewing MIBs. Contents This guide provides information about Dell PowerConnect W-Series ArubaOS 6.

Chapter 1 MIB Overview This chapter provides an overview of the ArubaOS Enterprise MIBs in the following sections: “MIB” on page 9 “SNMP” on page 10 “Traps” on page 11 MIB A Management Information Base (MIB) is a virtual database that contains information that is used for network management. Each managed device contains MIBs that define the properties of that device.
Figure 1 High Level MIB Hierarchy MIB is one of the elements of Simple Network Management Protocol (SNMP), which is used to manage network devices. To deliver information between devices, every object referred to in an SNMP message must be listed in the MIB. If a component of a device is not described in a MIB, that component cannot be recognized by SNMP— there is no information for SNMP managers and SNMP agents to exchange.
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 5. ArubaOS Enterprise MIBs support SNMPv1, SNMPv2, and SNMPv3. Table 5 MIB Keywords Keyword Description Sequence The sequence of objects of the MIB.
Terminal Server Function The terminal server function enables connection to remote-site serial devices. For example, device connection to serial ports enables telnet access via LAN. 12 | MIB Overview Dell PowerConnect W-Series ArubaOS 6.

To determine the OIDs, viewing the file snmp.h may be necessary, which is described in “SNMP File” on page 21. For additional information about MIB files, see “MIB” on page 9.
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 tree for the CTS MIB is illustrated in Figure 4 on page 21. The OID can be determined from the parent object as follows. wlsxEnterpriseMibModules is the parent object of the CTS MIB—its OID is 1.3.6.1.4.1.14823.2.2.1. wlsxCtsMIB MODULE-IDENTITY shows wlsxEnterpriseMibModules 11, which indicates 11 is appended to the OID of wlsxEnterpriseMibModules.

Chapter 3 Modules and Traps This chapter provides an overview of the ArubaOS MIB modules and traps. It all includes textual conventions.For information about downloading Dell MIB files, see “Downloading MIB Files” on page 13.
The Authentication MIBs are listed in the file aruba-auth.my. Controller Service Transport NOTE: All MIB tables and MIB OIDs in the Controller Transport Service were deprecated in ArubaOS 5.0 and are no longer supported. This module provides information about the Controller Transport Service. The Controller Transport Service (CTS) is used with the Mobility Manager for synchronizing configuration, database, and data sections.
Signal Noise Ratio (SNR) Module The Signal Noise Ratio (SNR) module provides information about signal quality and packets. One value of SNR is the signal quality during a sample period. The signal quality affects the quality of the transmitted packets. The available SNR values include signal strength (total, maximum, minimum). Additional information is the number of packets that were transmitted during the sample time. The SNR MIBs are listed in the file aruba-snr.my.
Voice Module The Voice module provides information about Voice call status and call detail reporting. The Voice MIBs are listed in the file aruba-voice.my. Wireless Local Area Network Module The wireless local area network (WLAN) module provides information about the Wireless Management System (WMS) in the Dell controller. The WLAN MIBs are listed in the file aruba-wlan.my. 28 | Modules and Traps Dell PowerConnect W-Series ArubaOS 6.
