Firmware Changes and Enhancements

  1. CtfddiStats are now working correctly. In a previous versions of firmware the statistics were not working correctly.
  2. SmartTrunking is supported with this release.

Supported Features

  1. The 9F426-03 features Local Management via the MMAC-Plus Environmental Module (EM). The Local Management application allows the user to monitor and control the module's IP address, subnet mask and default gateway configuration. The default community name/console password is public or <return>. Local Management can also be accessed by initiating a telnet to the 9F426-03's IP address.

  2. The 9F426-03 allows the user to connect the three front panel connected FDDI networks to the INB (Internal Network Bus) of the MMAC-Plus chassis.

  3. The INB2 is a high speed backplane that provides a potential for 2.5 Gbps of bandwidth. The INB2 bus uses a modified TDM design to provide the maximum bandwidth available on the bus to each module. The TDM for the bus is controlled by one of the modules. The function is called the monarch. The module that will become the monarch is selected automatically with no user intervention and it is transparent to the user. However if the module that is the Monarch is removed or any other module on INB2 is removed or reset for any reason, a monarch reset will take place. The process takes approximately 1.5 seconds. During this time no traffic will traverse the INB. When a new Monarch is selected all INB receive LEDs will be solid green and then begin to blink yellow with the rate of data traversing the INB. The following table is for the operation of the INB LED's during monarch selection:

  1. The default gateway interface found in local management is user selected for the following interface numbers: 1 -- SMB-1 This interface does not work for the default gateway.
    2 - SMB-10 This interface is connected via the EPIM port of the Environmental Module (EM).
    3 - Host The host port will direct the packets to the correct interface for the default gateway address via the look up tables.

    Configuration of the default interface will provide the path the packet shall use to get to the default gateway address. If the default gateway is off the EM then select interface 2, otherwise select interface 3 and allow the host to find the default gateway.

Installation and Configuration

  1. The 9F426-03 supports software image downloads to Flash EEPROM's for software upgrades thereby eliminating the need to physically access the module. The download may be done in-band, through the network, allowing remote upgrades from a central location. There is a 3 1/2 inch diskette included with the packaging of the 9F426-03. The disk is formatted in DOS. This diskette has the current Flash Image for the 9F426-03 stored on it. This is used as a back-up image for the 9F426-03 or it may be the current image that should be downloaded into the Flash EEPROM's of the 9F426-03. Please take time to verify the version on the diskette matches the current version installed on the 9F426-03.

  2. The 9F426-03 support the following FPIMs that must be installed prior to installing the module into the chassis:

    FPIM-00 -- Multimode Fiber, MIC connector
    FPIM-01 -- Multimode Fiber, SC connector
    FPIM-02 -- Unshielded Twisted Pair, RJ-45
    FPIM-04 -- Shielded Twisted Pair, RJ-45
    FPIM-05 -- Single Mode fiber, MIC connector
    FPIM-07 -- Single Mode fiber, SC connector

  3. The following instructions are for configuring full duplex via SNMP:

    To configure full duplex on an interface:

    OID Name: ctIfDuplex
    OID String: 1.3.6.1.4.1.52.4.3.3.2.1.1.5.interface #
    Description: Defines the duplex mode that the interface is set to operate in. For devices that do not support this capability a read will return standard (2) and a write attempt will return "BADVALUE".

      Integer
      other (1)
      standard (2)
      full (3)

Known Restrictions and Limitations

  1. Saving the IP Address in local management will cause the Module to perform a "soft" reset.

  2. In local management the frames filtered counter will always display zero. This will be addressed in the future.

  3. The INB hardware does not provide the full complement of statistics that are available on the other interfaces. Specifically, the only MIB-II Interface statistics supported by the INB interface are InOctets, InDiscards, and OutOctets; all other values are forced to zero (0). Consequently, the values for port 1 (INB) on the "Bridge Statistics" LM screen will always be displayed as zero (0).

  4. The dot1dStatic Group from the IETF Bridge MIB is supported, however, when creating and entry for the dot1dStaticReceivePort the only value that is allowed is the value "0" (zero).

  5. The ring map could display incorrect upstream neighbor information on rings that tend to be bouncy. Occasionally several stations indicate that they have the same upstream neighbor. This will be fixed in a future release.

  6. The following objects in the contType group of the Container MIB are not properly initialized: contTypeDevice
    contTypeSerialNumber
    contTypeContainingDevice
    contTypeContainingSerialNumber

  7. The use of a period in the password field is prohibited. The period symbol is reserved as a special character for Cabletron SmartSwitch products. If a period is being used in the password currently, change it to another character before downloading image version 1.04.11 or above.

  8. "Port Mirroring" is not supported on this module even though there is a screen in local management for this feature.
