SNMPBULKWALK(1)                               Net-SNMP                               SNMPBULKWALK(1)

NAME
       snmpbulkwalk - retrieve a subtree of management values using SNMP GETBULK requests

SYNOPSIS
       snmpbulkwalk [APPLICATION OPTIONS] [COMMON OPTIONS] AGENT [OID]

DESCRIPTION
       snmpbulkwalk is an SNMP application that uses SNMP GETBULK requests to query a network entity
       efficiently for a tree of information.

       An  object  identifier (OID) may be given on the command line.  This OID specifies which por‐
       tion of the object identifier space will be searched using GETBULK requests.   All  variables
       in  the subtree below the given OID are queried and their values presented to the user.  Each
       variable name is given in the format specified  in  variables(5).   If  no  OID  argument  is
       present, snmpbulkwalk will search MIB-2.

       If the network entity has an error processing the request packet, an error packet will be re‐
       turned and a message will be shown, helping to pinpoint why the request was malformed.

       If  the  tree search causes attempts to search beyond the end of the MIB, the message "End of
       MIB" will be displayed.

OPTIONS
       -Cc     Do not check whether the returned OIDs are increasing.  Some agents (LaserJets are an
               example) return OIDs out of order, but can complete the walk  anyway.   Other  agents
               return  OIDs  that  are out of order and can cause snmpbulkwalk to loop indefinitely.
               By default, snmpbulkwalk tries to detect this behavior and warns you when it hits  an
               agent acting illegally.  Use -Cc to turn off this behaviour.

       -Ci     Include  the  given  OID in the search range.  Normally snmpbulkwalk uses GETBULK re‐
               quests starting with the OID you specified and returns all results in  the  MIB  tree
               after  that OID.  Sometimes, you may wish to include the OID specified on the command
               line in the printed results if it is a valid OID in the  tree  itself.   This  option
               lets you do this.

       -Cn<NUM>
               Set  the  non-repeaters field in the GETBULK PDUs.  This specifies the number of sup‐
               plied variables that should not be iterated over.  The default is 0.

       -Cp     Upon completion of the walk, print the number of variables found.

       -Cr<NUM>
               Set the max-repetitions field in the GETBULK PDUs.  This specifies the maximum number
               of iterations over the repeating variables.  The default is 10.

       In addition to these options, snmpbulkwalk takes the common options  described  in  the  snm‐
       pcmd(1)  manual  page.   Note  that  snmpbulkget REQUIRES an argument specifying the agent to
       query and at most one OID argument, as described above.

EXAMPLE
       The command:

       snmpbulkwalk -v2c -Os -c public zeus system

       will retrieve all of the variables under system:

       sysDescr.0 = STRING: "SunOS zeus.net.cmu.edu 4.1.3_U1 1 sun4m"
       sysObjectID.0 = OID: enterprises.hp.nm.hpsystem.10.1.1
       sysUpTime.0 = Timeticks: (155274552) 17 days, 23:19:05
       sysContact.0 = STRING: ""
       sysName.0 = STRING: "zeus.net.cmu.edu"
       sysLocation.0 = STRING: ""
       sysServices.0 = INTEGER: 72

       In contrast to snmpwalk, this information will typically be gathered in a single  transaction
       with  the  agent,  rather than one transaction per variable found.  snmpbulkwalk is thus more
       efficient in terms of network utilisation, which may be especially important when  retrieving
       large tables.

NOTE
       As  the  name implies, snmpbulkwalk utilizes the SNMP GETBULK message, which is not available
       in SNMP v1.
