- <p>[manager] A major flaw was discovered with the agent handling. </p>
- <p>First, <c>TargetName</c> was never used as intended, as a unique
- identifier for the target (agent in this case). </p>
- <p>Second, <c>TargetName</c> had a <em>default value</em>, which meant
- that several agents could have the same <c>TargetName</c>, causing
- unpredictable behaviour in the manager. </p>
- <p>Third, <c>EngineID</c> was not a mandatory config option and had
- furthermore also a <em>default value</em>. </p>
-
- <p>These problems has been solved in the following way: </p>
- <p>First, a new set of api functions has been introduced (and documented):
- <seealso marker="snmpm#register_user">register_user/4</seealso>,
- <seealso marker="snmpm#register_user_monitor">register_user_monitor/4</seealso>,
- <seealso marker="snmpm#register_agent">register_agent/3</seealso>,
- <seealso marker="snmpm#unregister_agent">unregister_agent/2</seealso>,
- <seealso marker="snmpm#agent_info">agent_info/2</seealso>,
- <seealso marker="snmpm#update_agent_info">update_agent_info/4</seealso>,
- <seealso marker="snmpm#sync_get">sync_get/3,4,5,6</seealso>,
- <seealso marker="snmpm#async_get">async_get/3,4,5,6</seealso>,
- <seealso marker="snmpm#sync_get_next">sync_get_next/3,4,5,6</seealso>,
- <seealso marker="snmpm#async_get_next">async_get_next/3,4,5,6</seealso>,
- <seealso marker="snmpm#sync_set">sync_set/3,4,5,6</seealso>,
- <seealso marker="snmpm#async_set">async_set/3,4,5,6</seealso>,
- <seealso marker="snmpm#sync_get_bulk">sync_get_bulk/5,6,7,8</seealso> and
- <seealso marker="snmpm#async_get_bulk">async_get_bulk/5,6,7,8</seealso>
- that all use <c>TargetName</c> (and not, as previously, <c>Addr</c>
- and <c>Port</c>) to identify the agent (also the return value of
- <seealso marker="snmpm#which_agents">which_agents</seealso> has
- been changed). </p>
- <p>Second, for backward compatibility, the old functions still
- exist, but are no longer documented and are now wrappers for the
- new functions, including erroneous default value for EngineID and
- all. The TargetName is however generated from the provided
- <c>Addr</c>, <c>Port</c> and <c>Version</c> config options. </p>
- <p>Third, the behaviour of the
- <seealso marker="snmpm_user">SNMP manager user</seealso> has
- been changed to reflect this, i.e.
- <seealso marker="snmpm_user#handle_pdu">handle_pdu/4</seealso>,
- <seealso marker="snmpm_user#handle_trap">handle_trap/3</seealso>,
- <seealso marker="snmpm_user#handle_inform">handle_inform/3</seealso>,
- <seealso marker="snmpm_user#handle_report">handle_report/3</seealso>
- and the return-value of
- <seealso marker="snmpm_user#handle_agent">handle_agent/4</seealso>.
- The old (non-documented) callback-functions (using Addr and Port)
- will still be called if the agent was registered using the old
- registration functions. </p>

+ <p>[manager] A major flaw was discovered with the agent handling. </p>
+ <p>First, <c>TargetName</c> was never used as intended, as a unique
+ identifier for the target (agent in this case). </p>
+ <p>Second, <c>TargetName</c> had a <em>default value</em>, which meant
+ that several agents could have the same <c>TargetName</c>, causing

+ <p>Third, <c>EngineID</c> was not a mandatory config option and had
+ furthermore also a <em>default value</em>. </p>
+
+ <p>These problems has been solved in the following way: </p>
+ <p>First, a new set of api functions has been introduced (and documented):
+ <seealso marker="snmpm#register_user">register_user/4</seealso>,
+ <seealso marker="snmpm#register_user_monitor">register_user_monitor/4</seealso>,
+ <seealso marker="snmpm#register_agent">register_agent/3</seealso>,
+ <seealso marker="snmpm#unregister_agent">unregister_agent/2</seealso>,
+ <seealso marker="snmpm#agent_info">agent_info/2</seealso>,
+ <seealso marker="snmpm#update_agent_info">update_agent_info/4</seealso>,
+ <seealso marker="snmpm#sync_get">sync_get/3,4,5,6</seealso>,
+ <seealso marker="snmpm#async_get">async_get/3,4,5,6</seealso>,
+ <seealso marker="snmpm#sync_get_next">sync_get_next/3,4,5,6</seealso>,
+ <seealso marker="snmpm#async_get_next">async_get_next/3,4,5,6</seealso>,
+ <seealso marker="snmpm#sync_set">sync_set/3,4,5,6</seealso>,
+ <seealso marker="snmpm#async_set">async_set/3,4,5,6</seealso>,
+ <seealso marker="snmpm#sync_get_bulk">sync_get_bulk/5,6,7,8</seealso> and
+ <seealso marker="snmpm#async_get_bulk">async_get_bulk/5,6,7,8</seealso>
+ that all use <c>TargetName</c> (and not, as previously, <c>Addr</c>
+ and <c>Port</c>) to identify the agent (also the return value of
+ <seealso marker="snmpm#which_agents">which_agents</seealso> has
+ been changed). </p>
+ <p>Second, for backward compatibility, the old functions still
+ exist, but are no longer documented and are now wrappers for the
+ new functions, including erroneous default value for EngineID and
+ all. The TargetName is however generated from the provided
+ <c>Addr</c>, <c>Port</c> and <c>Version</c> config options. </p>
+ <p>Third, the behaviour of the
+ <seealso marker="snmpm_user">SNMP manager user</seealso> has
+ been changed to reflect this, i.e.
+ <seealso marker="snmpm_user#handle_pdu">handle_pdu/4</seealso>,
+ <seealso marker="snmpm_user#handle_trap">handle_trap/3</seealso>,
+ <seealso marker="snmpm_user#handle_inform">handle_inform/3</seealso>,
+ <seealso marker="snmpm_user#handle_report">handle_report/3</seealso>
+ and the return-value of
+ <seealso marker="snmpm_user#handle_agent">handle_agent/4</seealso>.
+ The old (non-documented) callback-functions (using Addr and Port)
+ will still be called if the agent was registered using the old
+ registration functions. </p>
