[manager] When the net_if process failed to send a message, for

it will return with a proper reason
(see snmpm:g,
snmpm:gn and

was asynchroneous, the new callback function,
handle_error
(see snmpm_user) is
called.

1.5.3 Incompatibilities
-
New sys configuration format.
Allthough the old configuration format still
works (if only the agent is used), it is no
longer documented and will eventually be
eliminated.
See application configuration or
configuration params for more info.
-
Three new interface modules have been introduced. One
for each of the individual parts of the application:
-
[agent]
snmpa
-
[manager]
snmpm
-
[compiler]
snmpc
The primary interface module, snmp
, still exist.
It contains the application generic functions. The
agent specific stuff still exist (for backward
compatibillity reasons), but has been deprecated and will
eventually be removed.
Some previously already deprecated functions has been
removed (since they in turn was dependent on deprecated
functions, see calendar).
-
[agent] The agent network interface api has changed.
See snmp agent net if,
-
[agent] The default agent audit trail log name has changed.
-
[compiler] Mib format has changed (see OTP-5053 above).
