Explanation / Answer

The snmpwalk command performs a sequence of chained GETNEXT requests automatically. It is a work saving command. Rather than having to issue a series of snmpgetnext requests, one for each object ID, or node, in a sub-tree, you can simply issue one snmpwalk request on the root node of the sub-tree and the command gets the value of every node in the sub-tree.

For example:

  % snmpwalk -mALL -v1 -cpublic snmp_agent_Ip_address system  SNMPv2-MIB::sysDescr.0 = STRING: ILOM machine custom description  SNMPv2-MIB::sysObjectID.0 = OID: SUN-ILOM-SMI-MIB::sunILOMSystems  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (16439826) 1 day, 21:39:58.26  SNMPv2-MIB::sysContact.0 = STRING: set via snmp test  SNMPv2-MIB::sysName.0 = STRING: SUNSPHOSTNAME  SNMPv2-MIB::sysLocation.0 = STRING:  SNMPv2-MIB::sysServices.0 = INTEGER: 72  SNMPv2-MIB::sysORLastChange.0 = Timeticks: (14) 0:00:00.14  SNMPv2-MIB::sysORID.1 = OID: IF-MIB::ifMIB  SNMPv2-MIB::sysORID.2 = OID: SNMPv2-MIB::snmpMIB  SNMPv2-MIB::sysORID.3 = OID: TCP-MIB::tcpMIB  SNMPv2-MIB::sysORID.4 = OID: RFC1213-MIB::ip  SNMPv2-MIB::sysORID.5 = OID: UDP-MIB::udpMIB  SNMPv2-MIB::sysORID.6 = OID: SNMP-VIEW-BASED-ACM-MIB::vacmBasicGroup  SNMPv2-MIB::sysORID.7 = OID: SNMP-FRAMEWORK-MIB::snmpFrameworkMIBCompliance  SNMPv2-MIB::sysORID.8 = OID: SNMP-MPD-MIB::snmpMPDCompliance  SNMPv2-MIB::sysORID.9 = OID: SNMP-USER-BASED-SM-MIB::usmMIBCompliance  SNMPv2-MIB::sysORDescr.1 = STRING: The MIB module to describe generic objects for network interface sub-layers  SNMPv2-MIB::sysORDescr.2 = STRING: The MIB module for SNMPv2 entities  SNMPv2-MIB::sysORDescr.3 = STRING: The MIB module for managing TCP implementations  SNMPv2-MIB::sysORDescr.4 = STRING: The MIB module for managing IP and ICMP implementations  SNMPv2-MIB::sysORDescr.5 = STRING: The MIB module for managing UDP implementations  SNMPv2-MIB::sysORDescr.6 = STRING: View-based Access Control Model for SNMP.
