![]() The snmpwalk command is used because it allows the user to chain GETNEXT requests together without having to enter unique commands for each and every OID or node within a sub-tree. The SNMP GETNEXT request is used to query an enabled device and take SNMP data from a device. ![]() Snmpwalk is the name given to an SNMP application that runs multiple GETNEXT requests automatically. The GET-Next command is a little more advanced and goes through a MIB tree from OID to OID pulling information. The GET command is used to take an Object Identifier ( OID) from the MIB. ![]() The most common ways are through the use of the GET or the GET-Next command. There are many different commands that you can use to query an SNMP agent. When the SNMP Manager queries the SNMP agent, data is taken from the MIB and sent to the SNMP Manager where it can be viewed with a network monitoring tool. On SNMP-enabled devices, an SNMP agent collects information from the device and stores it within a Management Information Base ( MIB) where this data is stored so that it can be accessed whenever the SNMP manager polls the SNMP agent. However, before we look at the snmpwalk command, we first need to look at how SNMP works. ![]() Today SNMP is one of the most popular networking protocols in the world and snmpwalk has become a go-to method for scanning multiple nodes at once. Since then SNMP data has been used to measure the system performance of devices across countless vendors to help ensure that networks stay up and running. In the late 1980’s, SNMP or the Simple Network Management Protocol first emerged as a solution for managing nodes within a network.
