SET command

pysnmp.hlapi.v1arch.setCmd(snmpDispatcher, authData, transportTarget, *varBinds, **options)

Creates a generator to perform one or more SNMP SET queries.

On each iteration, new SNMP SET request is send (RFC 1905#section-4.2.5). The iterator blocks waiting for response to arrive or error to occur.

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


Request options:

  • lookupMib - load MIB and resolve response MIB variables at the cost of slightly reduced performance. Default is True. Default is True.
  • 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]
  • varBinds (tuple) – A sequence of ObjectType class instances representing MIB variables returned in SNMP response.

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


The setCmd generator will be exhausted immediately unless a new sequence of varBinds are send back into running generator (supported since Python 2.6).
