UCD-SNMP Tutorial -- snmpwalk

Note: Much of this tutorial requires ucd-snmp-4.2.2!, so make sure you get it before running the commands found in this tutorial.

Note: A new tutorial for net-snmp 5.0 and above is available as well. The commands is the ucd-snmp specific tutorial will not work as expected if you are using net-snmp and not ucd-snmp.

The snmpwalk command essentially performs a whole series of getnexts automatically for you, and stops when it returns results that are no longer inside the range of the OID that you originally specified. If you wanted to get all of the information stored on a machine in the system MIB group, for instance, you could use this command to do so:
