Steps for Install net-snmp library in Windows. In this way you will be able to control the ethernet controller with command line.
- Download the last version net-snmp binary for windows from http://net-snmp.sourceforge.net/download. The file must look like net-snmp-X.X.X.X-X.win32.exe
- Install the downloaded file. Leave the default options. The packet will be install in c:\usr by default.
- Download the MIB file for the device
- Copy the mib file here c:\usr\share\snmp\mibs
- Add new line in the file c:\usr\etc\snmp\snmp.conf with the "mibs all" directive.
- Now you can test different commands for OID access, supported by this module. Their names you may see in the .mib file.

For most Linux OS, there is built in the same snmp tool in the kernel.
