## 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)](https://www.chedong.com/phpMan.php/man/variables/5/markdown)_.   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     
               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     
               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_
               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     

### -Cr_
               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)](https://www.chedong.com/phpMan.php/man/pcmd/1/markdown)_  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.
