NAME

       snmpbulkget - communicates with a network entity using SNMP GETBULK requests.

SYNOPSIS

       snmpbulkget [COMMON OPTIONS] [-Cn <num>] [-Cr <NUM>] AGENT OID [OID]...

DESCRIPTION

       snmpbulkget  is	an SNMP application that uses the SNMP GETBULK request to query a network entity efficiently for information.  One or more
       object identifiers (OIDs) may be given as arguments on the command line.  Each variable name is given in  the  format  specified  in  vari-
       ables(5).

       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.

OPTIONS

       -Cn<NUM>
	       Set the non-repeaters field in the GETBULK PDU.	This specifies the number of supplied variables that should not be iterated  over.
	       The default is 0.

       -Cr<NUM>
	       Set  the  max-repetitions  field in the GETBULK PDU.  This specifies the maximum number of iterations over the repeating variables.
	       The default is 10.

       In addition to these options, snmpbulkget takes the common options described in the snmpcmd(1) manual page.  Note that snmpbulkget REQUIRES
       an argument specifying the agent to query and at least one OID argument, as described there.

EXAMPLE

       The command:

       snmpbulkget -v2c -Cn1 -Cr5 -Os -c public zeus system ifTable

       will retrieve the variable system.sysDescr.0 (which is the lexicographically next object to system) and the first 5 objects in the ifTable:

       sysDescr.0 = STRING: "SunOS zeus.net.cmu.edu 4.1.3_U1 1 sun4m"
       ifIndex.1 = INTEGER: 1
       ifIndex.2 = INTEGER: 2
       ifDescr.1 = STRING: "lo0"
       et cetera.

NOTE

       As the name implies, snmpbulkget utilizes the SNMP GETBULK message, which is not available in SNMPv1.

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.
