Manual: snmpwalk
Tutorial: Tutorial
Code: apps/snmpwalk.c

Purpose

Issue a multiple SNMP GETNEXT operations to a remote agent, traversing all the data in an agent's implemented MIB tree below a certain point.

Command Line

The command line options are per the snmpcmd options.

The remaining option is an OID to walk (IE, "get all the data below this"). You can simulate an snmpwalk but issuing a bunch of snmpgetnext commands as well.

To find everything that an agent supports (or and you're allowed to see), try walking the agent with an OID of .1.3, which is the highest level OID that most agents will return data under.
