Changes from the Release 4.0 to 4.1
In our previous releases, the C agent or embedded agent was a part of AgentTookit. With release 4.1, the embedded agent is a separate product and is released as AdventNet Agent Toolkit C Edition. The run-time agent is now called 'C' agent instead of embedded agent.
This section lists the new features and modifications we have done in each module, such as Run-time agent, Mib Editor, Agent Compiler, Mib Browser, etc.
Run-time Agent
Agent Toolkit release 4.0 supports SNMP and HTTP interface for run-time agent. Some of the changes in SNMP Agent features and new features supported by HTTP Agent are listed out here.
API is changed to support new agent architecture.
Atomic set implementation between master agent and sub-agent

Features Supported in Patch Release 1.0
SNMP Table Row-level proxy is supported.
Proxy based on context name is supported for multiple instances of the same MIB.
The method FreeAllResources() is generated for each MIB in <AdventNet>/C-Agent/projects/<ProjectName>/agent/stubs/listenerifc.c file. This method will free all the agent resources and the resources allocated for the MIBs to which the code is generated.
Supports to provide HTTP 1.0 protocol access to the run-time agent.
Dynamic HTML page generation is supported using Server Side Includes (SSI) tags.
Provides a static HTML page with SSI tags, which is helpful to the user to customize the information.

In File menu, the concept of project is introduced. Each agent developed is considered a separate project.
Provides Settings menu for configuring SNMP, HTML, Database, and C/C++ Compiler.
Code generation is based on either 4.0 Model or 4.1 Model as specified in the Projects dialog box.

Features Supported in Patch Release 1.0
QNX and WindowsCE operating systems are supported in Mib Compiler.
Command Line Mib Compiler is supported.
Changes from the Release 3.2.1 to 4.0
API Changes
The MIBs package uses new MibParser which gives better performance. The following are the changes in MIB-related operations due to new MibParser:
All the modules defined in the import field should be present. Earlier even if imports, such as mib-2 from RFC1213-MIB failed, it will load the MIB after printing a warning message. Now it is mandatory that all the modules defined in the imports are present.
OID definition, such as the following will not work:
newNode OBJECT IDENTIFIER ::= { ModuleName.nodeName 1}
newNode OBJECT IDENTIFIER ::= { 1 3 6 .......}
newNode OBJECT IDENTIFIER ::= { 1 }
Module name should not start with a lower case letter or number.
Enumeration label should not start with a number.
Since multiple roots are shown in the Mib Tree now, get and getnext operation from the Mib Browser after selecting the module name will fail. You have to select the MIB node.
Three new methods will be generated for handler file in the code generation for embedded agent. They are
<ModuleName>ProcessRequests(): It has a vector that contains requested OIDs in the received request and PDU type. So, you can validate the received OID before processing them in the <ModuleName>ProcessReadReq() and <ModuleName>ProcessWriteReq() methods.
Update<ModuleName>(): It is called to update exact data structure after SET is successful for all received OIDs. It is used in the case of no storage for SNMP table.
Free<TableName>Vector(): It is not an API method. It is used to free the table. It is only for SNMP table.
Support for SNMPv3 USM and VACM remote configuration. That is, RFC2574(USM-MIB) and RFC2575(VACM-MIB) are implemented.
Changes from the Release 3.2 to 3.2.1
Mib Editor

Supports Minimal featured Database, such as Timesten, CloudScape, etc.
Provided a dll apadll.dll (only for Windows NT systems) which registers as a sub-agent to Windows NT master agent and acts as a proxy-forwarder, that is, forwards the request to the specified SNMP agent running in a different port.
Changes from the Release 3.1 to 3.1.1
Others
Running the agent in asynchronous mode.
Two aeadll.dll are provided (this is the dll which starts the AdventNet's SnmpAgent as a sub-agent in Windows).One dll in the /dll directory is jdk1.1.x compliant and the other in /dll/jdk1.2_dll is jdk1.2.x compliant.
Changes from the Release 3.0 to 3.1

Support for NOTIFICATION-GROUP and OBJECT-GROUP has been added.
MODULE-COMPLIANCE and AGENT-CAPABILITIES are not yet supported for editing. ( A MIB file with these two constructs can still be loaded in the Agent Toolkit; the support is lacking only in the wizard interface.)
"Save as" SMIv1 and SMIv2 have been provided for conversion between V1 to V2 and vice versa.
Support for publishing MIBs without AGENT-CLAUSE hooks has been provided.
API Changes
The package Snmp2.* is no longer supported.

Removed MIB dependencies for SnmpAgent and com.adventnet.snmp.snmp2.agent.*.Packaging of minimal agents are possible with the help of compiled approach.
The interface com.adventnet.snmp.mibs.agent.InitSnmpAgentData doesn't pass in SnmpAgent reference. SnmpAgent reference was required in earlier versions for TRAP support which can be obtained through use of SnmpTrapService and SnmpMibTrapService now.
Made TrapForwardingTable an interface. API users can now provide their own implementations of TrapForwardingTable.
Support for dynamically registering SNMP sub-agents.
Support for Access Control Lists to authenticate read and read-write access to managers.
