NAME

       snmpm_mpd - Message Processing and Dispatch module for the SNMP manager

DESCRIPTION

       The  module  snmpm_mpd implements the version independent Message Processing and Dispatch functionality in SNMP for the manager. It is sup-
       posed to be used from a Network Interface process ( Definition of Manager Net if ).

EXPORTS

       init_mpd(Vsns) -> mpd_state()

	      Types  Vsns = [Vsn]
		     Vsn = v1 | v2 | v3

	      This function can be called from the net_if process at start-up. The options list defines which versions to use.

	      It also initializes some SNMP counters.

       process_msg(Msg, TDomain, Addr, Port, State, NoteStore, Logger) -> {ok, Vsn, Pdu, PduMS, MsgData} | {discarded, Reason}

	      Types  Msg = binary()
		     TDomain = snmpUDPDomain
		     Addr = {integer(), integer(), integer(), integer()}
		     Port = integer()
		     State = mpd_state()
		     NoteStore = pid()
		     Logger = function()
		     Vsn = 'version-1' | 'version-2' | 'version-3'
		     Pdu = #pdu
		     PduMs = integer()
		     MsgData = term()

	      Processes an incoming message. Performs authentication and decryption as necessary. The return values should be passed  the  manager
	      server.

	      NoteStore is the pid() of the note-store process.

	      Logger is the function used for audit trail logging.

	      In the case when the pdu type is report , MsgData is either ok or {error, ReqId, Reason} .

       generate_msg(Vsn, NoteStore, Pdu, MsgData, Logger) -> {ok, Packet} | {discarded, Reason}

	      Types  Vsn = 'version-1' | 'version-2' | 'version-3'
		     NoteStore = pid()
		     Pdu = #pdu
		     MsgData = term()
		     Logger = function()
		     Packet = binary()
		     Reason = term()

	      Generates a possibly encrypted packet to be sent to the network.

	      NoteStore is the pid() of the note-store process.

	      MsgData  is the message specific data used in the SNMP message. In SNMPv1 and SNMPv2c, this message data is the community string. In
	      SNMPv3, it is the context information.

	      Logger is the function used for audit trail logging.

       generate_response_msg(Vsn, Pdu, MsgData, Logger) -> {ok, Packet} | {discarded, Reason}

	      Types  Vsn = 'version-1' | 'version-2' | 'version-3'
		     Pdu = #pdu
		     MsgData = term()
		     Logger = function()
		     Packet = binary()
		     Reason = term()

	      Generates a possibly encrypted response packet to be sent to the network.

	      MsgData is the message specific data used in the SNMP message. This value is received from the process_msg function.
