GETBULK command

async pysnmp.hlapi.asyncio.bulkCmd(snmpEngine: Any, authData: Any, transportTarget: Any, contextData: Any, nonRepeaters: Any, maxRepetitions: Any, *varBinds: Any, **options: Any) → SnmpResponse

Perform SNMP GETBULK.

(RFC 1905 Section 4.2.3)

Parameters:

  • snmpEngine (SnmpEngine) – Class instance representing SNMP engine.

  • authData (CommunityData or UsmUserData) – Class instance representing SNMP credentials.

  • transportTarget (UdpTransportTarget or Udp6TransportTarget) – Class instance representing transport type along with SNMP peer address.

  • contextData (ContextData) – Class instance representing SNMP ContextEngineId and ContextName values.

  • nonRepeaters (int) – One MIB variable is requested in response for the first nonRepeaters MIB variables in request.

  • maxRepetitions (int) – maxRepetitions MIB variables are requested in response for each of the remaining MIB variables in the request (e.g. excluding nonRepeaters). Remote SNMP engine may choose lesser value than requested.

  • *varBinds (ObjectType) – One or more class instances representing MIB variables to place into SNMP request.

Other Parameters:

**options –

Request options:

  • lookupMib - load MIB and resolve response MIB variables at the cost of slightly reduced performance. Default is True.

Returns:

  • errorIndication (str) – True value indicates SNMP engine error.

  • errorStatus (str) – True value indicates SNMP PDU error.

  • errorIndex (int) – Non-zero value refers to varBinds[errorIndex-1]

  • varBindTable (tuple) – A sequence of sequences (e.g. 2-D array) of ObjectType class instances representing a table of MIB variables returned in SNMP response, with up to maxRepetitions rows, i.e. len(varBindTable) <= maxRepetitions.

    For 0 <= i < len(varBindTable) and 0 <= j < len(varBinds), varBindTable[i][j] represents:

    • For non-repeaters (j < nonRepeaters), the first lexicographic successor of varBinds[j], regardless the value of i, or an ObjectType instance with the endOfMibView value if no such successor exists;

    • For repeaters (j >= nonRepeaters), the i-th lexicographic successor of varBinds[j], or an ObjectType instance with the endOfMibView value if no such successor exists.

    See RFC 3416 Section 4.2.3 for details on the underlying GetBulkRequest-PDU and the associated GetResponse-PDU, such as specific conditions under which the server may truncate the response, causing varBindTable to have less than maxRepetitions rows.

Raises:

pysnmp.error.PySnmpError – Or its derivative indicating that an error occurred while performing SNMP operation.
