The module snmpm_mpd implements the version independent
Message Processing and Dispatch functionality in SNMP for the manager.
It is supposed to be used from a Network Interface process
(Definition of Manager Net if).
Types:
Vsns = [Vsn]
Vsn = v1 | v2 | v3
This function can be called from the net_if process at startup. The options list defines which versions to use.
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. Thes value is received from the
process_msg
function.
