snmpa_network_interface
(snmp)Behaviour module for the SNMP agent network interface.
This module defines the behaviour of the agent network
interface. A snmpa_network_interface
compliant module
must export the following functions:
The semantics of them and their exact signatures are explained below.
But this is not enough. There is also a set of mandatory messages which the network interface entity must be able to receive and be able to send. This is described in chapter snmp_agent_netif.
Functions
start_link(Prio, NoteStore, MasterAgent, Opts) -> {ok, Pid} | {error, Reason}
Prio = priority()
NoteStore = pid()
MasterAgent = pid()
Opts = [opt()]
opt() = {verbosity, verbosity()} | {versions, versions()} | term()
versions() = [version()]
version() = v1 | v2 | v3
Start-link the network interface process.
NoteStore
is the pid of the note-store process and
MasterAgent
is the pid of the master-agent process.
Opts
is an (basically) implementation dependent list of
options to the network interface process. There are however
a number of options which must be handled:
versions
and verbosity
.
info(Pid) -> [{Key, Value}]
Pid = pid()
The info returned is basically up to the implementer to decide. This implementation provided by the application provides info about memory allocation and various socket information.
The info returned by this function is returned together with other
info collected by the agent when the
info function is called
(tagged with with the key net_if
).
verbosity(Pid, Verbosity) -> void()
Pid = pid()
Verbosity = verbosity()
Change the verbosity of a running network interface process.
get_log_type(Pid) -> {ok, LogType} | {error, Reason}
Pid = pid()
LogType = atl_type()
Reason = term()
The Audit Trail Log is managed by the network interface process. So, it is this process that has to retrieve the actual log-type.
set_log_type(Pid, NewType) -> {ok, OldType} | {error, Reason}
Pid = pid()
NewType = OldType = atl_type()
Reason = term()
The Audit Trail Log is managed by the network interface process. So, it is this process that has to do the actual changing of the type.
See set_log_type for more info.
