MODULE
MODULE SUMMARY
DESCRIPTION
The module snmpa_mpd implements the version independent Message Processing and Dispatch functionality in SNMP for the agent. It is supposed to be used from a Network Interface process (Definition of Agent Net if).
EXPORTS
Types:
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.
Types:
Processes an incoming packet. Performs authentication and decryption as necessary. The return values should be passed the agent.
generate_response_msg(Vsn, RePdu, Type, ACMData) -> {ok, Packet} | {discarded, Reason}
Types:
Generates a possibly encrypted response packet to be sent to the network. Type is the #pdu.type of the original request.
generate_msg(Vsn, Pdu, MsgData, To) -> {ok, PacketsAndAddresses} | {discarded, Reason}
Types:
Generates a possibly encrypted request packet to be sent to the network.
MsgData is the message specific data used in the SNMP message. This value is received in a send_pdu or send_pdu_req message from the agent. In SNMPv1 and SNMPv2c, this message data is the community string. In SNMPv3, it is the context information. To is a list of the destination addresses and their corresponding security parameters. This value is also received from the requests mentioned above.
discarded_pdu(Variable) -> void()
Types:
Increments the variable associated with a discarded pdu. This function can be used when the net_if process receives a discarded_pdu message from the agent.
