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.
