       More than 600 precompiled MIBs are supplied.

   71. New Functionality in 2.30

       Recorder

       Options to handle large MIBs (maximum table size, exclude object trees).
       Option to slow down retrieval (in order not to overwhelm sensitive device with management requests).
       Recorder now automatically recovers from agent's inability to handle multi-variable GETNEXT PDUs.

       Simulator

       Multiple community strings per agent.
       Value space lookup failure now returns DEFVAL clause of MIB object. This simulates correct dynamic row creation semantics.
       Solaris native threads support takes advantage of multi-processor systems.
       More efficient/accurate trap generation.

       Miscellaneous

       TCL package with MIMIC extensions loadable into any TCL-based shell.
       More robust scripting with TCL-style error handling (catch).
       Better diagnostics for all tools.
       More than 550 precompiled MIBs are supplied.

   72. New Functionality in 2.23

       Windows Support

       Windows NT 4.0 is fully supported. Windows 95 is supported with minor limitations.

       Computer Associates Unicenter(R) TNG Support

       Support for Unicenter TNG agents.

       Year 2000

       Minor Year 2000 fixes.

       Miscellaneous

       Agents can be instructed to drop PDUs at a configurable rate.
       Recorder can record subsets of large tables.
       More than 500 precompiled MIBs are supplied.

   73. New Functionality in 2.20

       RedHat Linux 5.x Support

       RedHat Linux 5.x is fully supported.

       Configurable Network Mask

       You can now set any subnet mask for each agent instance.

       Miscellaneous

       Scripting language has been improved: you can now create/delete agents, pause at any time, etc.
       Performance improvements.
       MIMICView is now based on the latest Tcl/Tk 8.0.

   74. New Functionality in 2.10

       SMIv2 BITS

       The SMIv2 BITS construct is now supported in MIBs such as RMON-2, HCRMON, etc.

       Maximum PDU size

       The maximum PDU size is configurable per agent instance. MIMIC responds with the TOO_BIG error status for PDU overflow.

       PDU Tracing

       SNMP PDUs can be traced per agent instance. The PDU type and each variable are logged.

   75. New Functionality in 2.00

       SNMP SET

       This release adds support for SNMP SETs. A management application can perform an SNMP SET on all objects that have read-write access in the view with the agent's write-community name.
       MIMIC performs syntactical checking on the values, to make sure that they conform in type and that the value is legal given SIZE and range restrictions.
       New entries are added to tables by performing a SET on any column in the new row. New objects assume their default value as specified in the DEFVAL clause.

       Traps

       This release provides for TRAP PDU generation. The "trap_periodic" simulation generates periodic traps with the specified frequency. The following aspects of trap generation are configurable at run-time for each trap for each agent instance:

       • frequency
       • cutoff time
       • variable values

       
       For example, you can generate the linkUp trap every 15 seconds for the next 300 seconds, and send a different ifIndex for each.

       250 Agents

       MIMIC Professional edition scales up to 250 agent simulations on all supported platforms.

       RMON2 support

       MIMIC fully supports MIB objects that are 64-bit counters, such as those in the IF-MIB (RFC 1573).

       Persistence

       MIMIC will now give you the option of saving changed simulations when stopping a simulation. Any simulation that is changed via user-interface Set Value or SNMP SET requests will ask you to save it when you use Agent-->Stop. The changed values are accessible in subsequent simulation sessions.

       Scripting

       In addition to the interactive graphical user interface in MIMICView, simulations are now accessible in batch-mode scripting via the new MIMICShell tool mimicsh.
       mimicsh provides a TCL-based scripting environment with access to MIMIC. All operations that can be done with MIMICView in interactive mode can be done in scripts in mimicsh.

       Miscellaneous

       At least 100 more MIBs have been added bringing the total above 400.
       Several GUI improvements have been implemented:

       • Agent icons are now displayed with configurable bitmaps. This gives at-a-glance indication of the simulation. The bitmaps are determined by the device name, and the regular expressions of bitmaps in the bitmap/ subdirectory.
       • Right-clicking on an agent icon brings up the Agent menu.
       • Per-agent statistics are now available with Agent-->Statistics.
