Cisco Nexus OS MIB OID Environment Temperature

Hello,

I was wondering, if someone could please advise on the MIB OIDs required to install on NMS to receive and process SNMP Ennv Temp Traps of NXOS [9k,5k, and 2k].

 

Thanks,

Martin

Thank you Sergiu.

However, I was looking into NX-OS specific MIBs as suggested here:

 

sing Passive FTP to Access and Download the MIB Files

To access MIB files using passive FTP, you must know the names of the MIB files that you want to download. See the MIB support list for the names of supported MIBs. This procedure assumes that your passive FTP utility has UNIX-like commands.

Procedure
Step 1  Access ftp.cisco.com using passive FTP.
Step 2  Log in with your Cisco.com username and password, or as anonymous, with your e-mail address.
Step 3  Enter cd /pub/mibs/v2/ to change directories.
Step 4  Use the get command to copy the desired files to your local system.
Step 5  Use the quit command to exit passive FTP.

Understanding the ENTITY-MIB and Extensions

The ENTITY-MIB provides basic management and identification of physical and logical entities within a network device. Cisco NX-OS support for the ENTITY-MIB focuses on the physical entities within a device. This MIB provides details about each module, power supply, and fan tray within a switch chassis. It gives enough information to correctly map the containment of these entities within the switch, building up a chassis view.

Cisco has developed a number of private extensions to the ENTITY-MIB to provide more details for these physical entities. Each MIB extension shares the common index value, entPhysicalIndex, which allows the management application developer to link information across multiple MIBs.

This table lists the Cisco MIB extensions that are linked to the ENTITY-MIB by entPhysical Index.Table 2 ENTITY-MIB ExtensionsMIBDescription

CISCO-ENTITY-ASSET-MIB

Provides manufacturing asset number and revision information per physical entity in the switch.

CISCO-ENTITY-EXT-MIB

Extends the entityPhysicalTable for modules with processors. For each of these modules, this MIB provides memory statistics and LED information.

CISCO-ENTITY-FRU-CONTROL-MIB

Manages field-replaceable units, such as power supplies, fans, and modules.

CISCO-ENTITY-SENSOR-MIB

Provides sensor data for environmental monitors such as temperature gauges.

CISCO-IMAGE-UPGRADE-MIB

Provides module image management based on entPhysicalIndex.

Hi @Netmart 

You can search for OIDs here: https://github.com/cisco/cisco-mibs/blob/main/oid/CISCO-ENVMON-MIB.oid

Once you found the OID, double check the details of it on SNMP Object Navigator: https://snmp.cloudapps.cisco.com/Support/SNMP/do/BrowseOID.do?local=en

 

Take care,

Sergiu
