Compiling SNMP MIBs

Uploading MIBs

To upload a MIB file:

Select Network Monitoring > Admin.
The Admin page is displayed.
Select SNMP MIB Compiler in the Operations section of the Admin page.
Click Upload MIB.
Browse and upload the MIB file from the appropriate location where the MIB file is stored.
The MIB file you have uploaded is displayed in the pending node of the MIB tree. You can now view and compile this MIB file.
Note:
- The filename must be the same as the MIB being processed.
- Download SRX SNMP MIBs from http://www.juniper.net/techpubs/software/index_mibs.html.
- Zip folders with .tgz extensions are not supported. You must extract the MIB files before uploading.
  
  Files with .txt and .mib extensions are only supported.

Compiling MIBs

Before you compile a MIB file, ensure that you have uploaded the MIB file. The MIB file should be displayed in the pending node of the MIB tree for you to be able to compile the MIB file.

To compile a MIB file:

Select Network Monitoring > Admin.
The Admin page is displayed.
Select SNMP MIB Compiler in the Operations section of the Admin page.
From the pending node of MIB tree, right-click the MIB file you want to compile and select Compile MIB.
You can view the results of the MIB compilation in the MIB Console section of Admin page. If the MIB file is compiled successfully, you will receive a log entry “MIB parsed successfully”. If the MIB file cannot be complied, you will receive an error message.

If a MIB file is compiled successfully, the MIB file will be moved from the pending node to the compiled node in the MIB tree.

Viewing MIBs

You can view MIB files in the compiled state or in the pending state.

To view a MIB file:

Select Network Monitoring > Admin.
The Admin page is displayed.
Select SNMP MIB Compiler in the Operations section of the Admin page.
Right-click the MIB file you want to view and select View MIB.
The View MIB pop-up window displays the MIB file. Use the scroll bar to view the contents of the MIB file.

Deleting MIBs

You can delete MIB files in the compiled state or in the pending state.

To delete a MIB file:

Select Network Monitoring > Admin.
The Admin page is displayed.
Select SNMP MIB Compiler in the Operations section of the Admin page.
Right-click the MIB file you want to delete and select Delete MIB.
Click Yes.
