1 SNMP Release Notes
1.1 SNMP Development Toolkit 4.5
Version 4.5 supports code replacement in runtime from/to
version 4.4.1 and 4.4.
1.1.1 Improvements and new features
-
[manager] Introduced the
inform request behaviour
configuration option to allow the user to specify
how/when the manager shall acknowledge inform-request's.
Own Id: OTP-5733
-
[manager] In order to improve application behaviour,
all callback function (see the
snmpm_user behaviour)
calls
are now done by spawned processes (and not as previously
by the SNMP manager server process).
Own Id: OTP-5726
-
[manager] In order to present the various error
reason's returned by the manager, a
format_reason
function has been added.
The error reasons this function handles are those
returned by the (sync and async) get, get-next,
get-bulk and set-functions
(see the snmpm module)
as well as the
Reason
argument of the
handle_error
function of the
user callback module.
Own Id: OTP-5581
Aux Id: Seq 9870
1.1.2 Reported Fixed Bugs and Malfunctions
-
[manager] The (error) report according to RFC 2572, chapter
7.2 point 6) was never sent.
Own Id: OTP-5742
-
[agent] Check of notification name collision
could fail due to incorrect record name (assumed to
be
#trap
, but could also be #notification
).
This only cases a problem when the application is
compiled with the strict_record_tests option.
Own Id: OTP-5740
-
[agent] Table get-request failure in some cases.
Own Id: OTP-5732
Aux Id: Seq 10087
-

Version 4.4.1 supports code replacement in runtime from/to
version 4.4.
1.2.1 Improvements and new features
-
[manager] Add monitoring of the SNMP manager.
The SNMP application consists of two different
runtime parts, the agent and the manager. They are
independent of each other. The agent is "permanent"
and the manager "transient". In order to handle
manager crashes a simple
monitor
(and demonitor)
function has been added.
Own Id: OTP-5720
1.2.2 Reported Fixed Bugs and Malfunctions
-
[manager] If sending a set-request containing an
'OCTET STRING' with an invalid integer (valid integer
are 0-255), the encoding will fail and cause the
net_if process to crash.

[manager] The out packet counter was not incremented for
sent v1/v2 messages.

Own Id: OTP-5678
-
Bad handling of error cases (corrupt log file) when
converting log files (i.e. when calling the function
log_to_txt).
Own Id: OTP-5703

This argument is passed on to the net-if process. The net-if

[manager]
report
message with incorrect security info
(e.g. securtyModel and/or securityLevel) was ignored (dropped,

situation, the user will be informed, either via the
