iDRAC MIB

The Integrated Dell Remote Access Controller (iDRAC) MIB (filename iDRAC-SMIv1.mib/ iDRAC-SMIv2.mib) is the MIB

supported by the Integrated Dell Remote Access Controller 7 and later versions (iDRAC7, iDRAC8 and iDRAC9). This MIB

provides management data that allows you to monitor devices and software on a system via an out-of-band connection to the

iDRAC7 and later of a system.

NOTE: From iDRAC7 firmware release r1.30.30 or later, the iDRAC7 and later MIB file is published in both types of SMI

(Structure of Managed Information) notations: SMIv1 and SMIv2. The SMIv1 copy of the iDRAC7 and later MIB file is named

iDRAC-SMIv1.mib. And the SMIv2 copy is named iDRAC-SMIv2.mib. Prior to iDRAC7 firmware release r1.30.30, only a SMIv1

copy was published. And the file name of the SMIv1 copy was iDRAC-MIB.txt.

iDRAC Supported SNMP Versions

The following table identifies the SNMP versions that support iDRAC for the given SNMP operations.

Table 324. iDRAC Supported SNMP Versions

SNMP Operations Supported SNMP version

GET, GETNEXT, GETBULK SNMP v1, v2c and v3

TRAP SNMP v1, SNMP v2c and SNMP v3

NOTE: iDRAC does not support the SNMP SET operation for any data.

NOTE: iDRAC7 firmware release r1.30.30 or later supports SNMP query operations (GET, GETNEXT, GETBULK) through

the SNMPv3 protocol. In addition to supporting query operations through the SNMP v1 and SNMP v2c protocols, SNMP

User Security Model (USM) is supported.

iDRAC SNMP Data Security Features

iDRAC firmware supports the following data security features:

● SNMP security lockout feature

○ iDRAC supports a simply, non-configurable SNMP security lockout feature. If more than six SNMPv3 USM authentication

failures occur within a 2-minute window, then the iDRAC SNMP Agent blocks all subsequent SNMPv3 requests/queries

for 10 minutes.

● Restriction of access to sensitive data

○ Some of the MIB data that iDRAC supports can only be accessed via SNMPv3 queries. Access to such data is blocked for

SNMPv1 and SNMPv2c queries.

○ Currently, the following one attribute, and one table, are considered to be “sensitive” data and have this restriction:

￭ numLCLogEntries (which has an SNMP OID of: 1.3.6.1.4.1.674.10892.5.4.300.2.0)

￭ lcLogTable (which has an SNMP OID of: 1.3.6.1.4.1.674.10892.5.4.300.90)
