Méthodes publiques

Méthode Description
Discovery ( SecureAgentParameters param ) : bool

Perform SNMP version 3 discovery operation. This is the first operation that needs to be performed on a newly accessed agent to retrieve agentId, agentBoots and agentTime values, critical for further authentication and privacy operations.
DiscoveryAsync ( SecureAgentParameters param, SnmpAsyncResponse callback ) : bool

Make an async discovery request for protocol version 3.
Request ( Pdu pdu, IAgentParameters agentParameters ) : SnmpPacket

Make SNMP Request

Make SNMP request. With this method you can make blocked SNMP version 1, 2 and 3 requests of type GET, GET-NEXT, GET-BULK, SET and REPORT (request types have to compatible with the SNMP protocol version you are using). This method will pass through any exceptions thrown by parsing classes/methods so see individual packet classes, ASN.1 type classes, authentication, privacy, etc. classes for exceptions thrown.

RequestAsync ( Pdu pdu, IAgentParameters agentParameters, SnmpAsyncResponse responseCallback ) : bool

Make SNMP request. With this method you can make blocked SNMP version 1, 2 and 3 requests of type GET, GET-NEXT, GET-BULK, SET and REPORT (request types have to compatible with the SNMP protocol version you are using). This method will pass through any exceptions thrown by parsing classes/methods so see individual packet classes, ASN.1 type classes, authentication, privacy, etc. classes for exceptions thrown.
UdpTarget ( IPAddress peer ) : System

Constructor

Initializes the class with defaults for timeout (2000ms = 2 seconds), retry (two) and agent UDP port number (161).

UdpTarget ( IPAddress peer, int port, int timeout, int retry ) : System

Constructor.

Method Details

Discovery() public méthode

Perform SNMP version 3 discovery operation. This is the first operation that needs to be performed on a newly accessed agent to retrieve agentId, agentBoots and agentTime values, critical for further authentication and privacy operations.
public Discovery ( SecureAgentParameters param ) : bool
param SecureAgentParameters class instance that will be updated /// with discovered agent values. This class with be reset to its defaults prior to agent /// discovered values so do not store any critical information in it prior to calling the /// discovery method
Résultat bool

DiscoveryAsync() public méthode

Make an async discovery request for protocol version 3.
public DiscoveryAsync ( SecureAgentParameters param, SnmpAsyncResponse callback ) : bool
param SecureAgentParameters Agent parameters
callback SnmpAsyncResponse Callback method
Résultat bool

Request() public méthode

Make SNMP Request
Make SNMP request. With this method you can make blocked SNMP version 1, 2 and 3 requests of type GET, GET-NEXT, GET-BULK, SET and REPORT (request types have to compatible with the SNMP protocol version you are using). This method will pass through any exceptions thrown by parsing classes/methods so see individual packet classes, ASN.1 type classes, authentication, privacy, etc. classes for exceptions thrown.
Thrown on SNMPv3 requests when authentication password /// is not specified on authNoPriv or authPriv requests in SecureAgentParameters or if incoming packet /// authentication check failed. /// /// With SNMP ver1 and ver2c, authentication check fails when invalid community name is parsed in the reply. Thrown on SNMPv3 requests when privacy password is not /// specified in SecureAgentParameters on authPriv requests. Thrown in following cases: /// /// * IAgentParameters.Valid() returned false. SnmpException.ErrorCode is set to SnmpException.InvalidIAgentParameters /// * No data received on request. SnmpException.ErrorCode is set to SnmpException.NoDataReceived /// * Invalid RequestId in reply. SnmpException.ErrorCode is set to SnmpException.InvalidRequestId ///
public Request ( Pdu pdu, IAgentParameters agentParameters ) : SnmpPacket
pdu Pdu Pdu class (do not pass ScopedPdu)
agentParameters IAgentParameters Security information for the request. Use /// for SNMP versions 1 and 2 requests. Use for SNMP version 3 /// requests.
Résultat SnmpPacket
