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

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

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

    78. 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.

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

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

      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.

      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.

      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.
