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.
