snmpbulkget - communicate with a network entity using SNMP GETBULK requests SYNOPSIS
snmpbulkget [application options] [common options] oid [oid...] DESCRIPTION
The snmpbulkget utility is an SNMP application that uses the SNMP GETBULK operation to send information to a network manager. You can spec- ify one or more object identifiers (OIDs) on the command line. Each variable name must be entered in the format specified in snmp_vari- ables(4). If the network entity has an error processing the request packet, an error packet is returned and a message displayed, indicating the way in which the request was malformed. OPTIONS
The following options are supported: -Cnnum 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. -Crnum 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 this option, snmpbulkget takes the common options described in the snmpcmd(1M) manual page. EXAMPLES
Example 1: Retrieving Multiple Objects The following snmpbulkget command retrieves the variable system.sysDescr.0 (which is the lexicographically next object to system) and the first five objects in the ifTable: # snmpbulkget -v2c -Cn1 -Cr5 -Os -c public zeus system ifTable This command produces output such as the following: 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" [...] ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWsmcmd | +-----------------------------+-----------------------------+ |Interface Stability |External | +-----------------------------+-----------------------------+ EXIT STATUS
0 Successful completion. 1 A usage syntax error. A usage message is displayed. Also used for timeout errors. 2 An error occurred while executing the command. An error message is displayed. SEE ALSO

snmpbulkwalk - retrieve a subtree of management values using SNMP GETBULK requests SYNOPSIS
snmpbulkwalk [APPLICATION OPTIONS] [COMMON OPTIONS] [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. 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. SEE ALSO
