SnmpWalk (Command-line Tool)

Overview

SNMP is a unified protocol of network monitoring and network device management. All active network devices support SNMP. Besides that, SNMP is supported by major operational systems and a large number of network applications.

SnmpWalk allows you to detect a set of variables that are available for reading on an individual device. You can obtain a full list or just part. By analyzing the results of a network device scan obtained with SnmpWalk, you can develop a list of supported MIBs and, in this way, obtain full descriptions of variables and possible values. Besides that, MIB documents contain information about SNMP variables that are available only for writing. After analyzing information retrieved with SnmpWalk from hardware or software SNMP sources, you can use SnmpSet and SnmpGet tools to change and obtain values.

The value of SnmpWalk is not limited to only the SNMP analysis of supported features. This tool can efficiently get SNMP tables and read whole sections of variables. This mainly refers to tables that are often used for presenting statistical and status information.

SnmpWalk is a command-line tool, which makes possible its use in scripts. This tool supports modern IPv6 in addition to the standard IPv4. Moreover, SnmpWalk allows you to use a simple version of SNMPv1/SNMPv2c and also supports a safe version of SNMPv3.
