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 portion 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 returned 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 requests 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 supplied 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 snmpcmd(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.
