       snmpbulkwalk - communicates with a network entity using SNMP BULK Requests.


       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 vari-
       ables 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.

       -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 indef-
	       initely.   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.

	       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.

	       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.

       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 transac-
       tion 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.

       As the name implies, snmpbulkwalk utilizes the SNMP GETBULK message, which is  not  avail-
       able in SNMP v1.
