To interact with a SNMP device, deviceWISE needs a copy of the device’s MIB file. The MIB file describes SNMP network elements as a list of data objects. The purpose of the MIB is to translate numerical strings into human-readable text.
When an SNMP device sends a trap or other message, it identifies each data object in the message with a number string called an object identifier, or OID. The MIB associates a text label to each OID. deviceWISE can then use the MIB as a codebook for translating the OID numbers into a human-readable display. Without the MIB, the message is just a meaningless string of numbers.
Importing the MIB file
Each SNMP device has its own MIB file that describes the elements unique to it. To interact with a device, deviceWISE needs a copy of the device’s MIB file. The following steps show where the MIB files are stored on the deviceWISE node and how you can copy the files to that location.
- From the Workbench left pane, expand the deviceWISE
node you want to verify and select the Administration
icon.
- Select the Staging Browser tab.
- Select the Create Directory button
to create a directory named mibs.
- Select the mibs directory so that it is
highlighted.
- Select the Put button to copy the
MIB file into the mib directory.
- Once you press the Select button, you will be asked
if you want to upload the file to the /mibs/ directory.
Select the Yes button and the MIB file will be copied
to the deviceWISE node.
