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.

Example GET commands:
---------------------
//Get the module name
snmpget -v1 -c read 192.168.1.100 .1.3.6.1.4.1.42505.6.1.1.0
DENKOVI-MIB::Denkovi.6.1.1.0 = STRING: "smartDEN IP-16R Module"

//Get SmartDEN IP-16R system date
snmpget -v1 -c read 192.168.1.100 .1.3.6.1.4.1.42505.6.2.1.0
DENKOVI-MIB::Denkovi.6.2.1.0 = STRING: "15/09/2014"

//Get SmartDEN IP-16R system time
snmpget -v1 -c read 192.168.1.100 .1.3.6.1.4.1.42505.6.2.2.0
DENKOVI-MIB::Denkovi.6.2.2.0 = STRING: "07:19"

//Get all the 16 relays state
snmpget -v1 -c read 192.168.1.100 .1.3.6.1.4.1.42505.6.3.1.0
DENKOVI-MIB::Denkovi.6.3.1.0 = INTEGER: 4

//Get the relay 1
snmpget -v1 -c read 192.168.1.100 .1.3.6.1.4.1.42505.6.2.3.1.3.0
DENKOVI-MIB::Denkovi.6.2.3.1.3.0 = INTEGER: 0

//Get the relay 16
snmpget -v1 -c read 192.168.1.100 .1.3.6.1.4.1.42505.6.2.3.1.3.15
DENKOVI-MIB::Denkovi.6.2.3.1.3.15 = INTEGER: 1

Example SET commands:
---------------------
//Set all the 16 relays ON
snmpset -v1 -c write 192.168.1.100 .1.3.6.1.4.1.42505.6.3.1.0 i 65535
DENKOVI-MIB::Denkovi.6.3.1.0.0 = INTEGER: 65535

//Set all the 16 relays OFF
snmpset -v1 -c write 192.168.1.100 .1.3.6.1.4.1.42505.6.3.1.0 i 0
DENKOVI-MIB::Denkovi.6.3.1.0.0 = INTEGER: 0

//Set relay 1 ON
snmpset -v1 -c write 192.168.1.100 .1.3.6.1.4.1.42505.6.2.3.1.3.0 i 1
DENKOVI-MIB::Denkovi.6.2.3.1.3.0 = INTEGER: 1

//Set relay 1 OFF
snmpset -v1 -c write 192.168.1.100 .1.3.6.1.4.1.42505.6.2.3.1.3.0 i 0
DENKOVI-MIB::Denkovi.6.2.3.1.3.0 = INTEGER: 0

//Set relay 16 ON
snmpset -v1 -c write 192.168.1.100 .1.3.6.1.4.1.42505.6.2.3.1.3.15 i 1
DENKOVI-MIB::Denkovi.6.2.3.1.3.15 = INTEGER: 1

//Set relay 16 OFF
snmpset -v1 -c write 192.168.1.100 .1.3.6.1.4.1.42505.6.2.3.1.3.15 i 0
DENKOVI-MIB::Denkovi.6.2.3.1.3.15 = INTEGER: 0
