# Net-SNMP notes

## Getting communication with devices

Once you have a device to talk to with, say, IP 192.168.0.100, use the snmpwalk command to communicate with it, as follows:

\$ snmpwalk -OsS -c public -v 1 192.168.0.100 private


This will query the device for all variables under the "private" node (for the protocol basics, see reference this snmp tutorial page).

To get a value of a specific variable, replace the "private" word for the name (or the SNMP path/code) of the variable. If you are using the name, don't forget to properly install the MIB database so net-snmp can recognize variable names. For installing a MIB database, see net-snmp FAQ.
