FNB Configuration
The FNB Configuration Menu (Figure 1) contains menu selections that allow you to configure the attachment of an FDDI Switch Module to the Flexible Network Buses on the chassis’ backplane, and to display an illustration that shows the topology of the FNB’s FDDI rings connected to that module.
In earlier versions of SmartSwitch 9000 Module Local Management, the FNB

FNB Resource Configuration
The 9F426-02 FDDI Switch Module is capable of bridging/switching any three, of five possible interfaces, depending on the way you configure the module. The module’s INB connection is fixed (not user-configured).
The FNB Resource Configuration Screen (Figure 2) allows you to connect both front panel ports, both FNB ports, or one front panel and one FNB port to the bridge/switch. Redirecting one or both of the module’s front panel FDDI interfaces to the FNB backplane creates an INB to FNB bridge/switch product that allows migration from FNB modules to INB modules.
The SmartSwitch 9000 FNB backplane is composed of two FDDI Networks (FNB­1 and FNB-2). The FNB Resource Configuration Screen lists all possible connections a module can support on the FNB, displays the current connection, and allows you to change the connection.

FNB Resource Configuration Screen Fields
The following information briefly explains each FNB Resource Configuration Screen field.
Current FDDI Con
Displays the current connections of the selected module to the SmartSwitch 9000’s FNB.
Config ID
Displays an identification number that is automatically assigned to each configuration.
FDDI Connections
Displays all possible connections of the selected module to the SmartSwitch 9000’s FNB (For a description of each of these connections, refer to Table 2).

Changing the Current FNB Connection

To change the current FNB connection:
1. Use the arrow keys to highlight a desired FDDI connection.
2. Press the Return key.
3. The connection you selected appears in the Current FDDI Con field.
4. Use the arrow keys to highlight SAVE at the bottom of the screen and press the
Return key.
The message “SAVED OK” appears. This message indicates that the FNB connection you selected has been implemented. If you exit without saving, the message “NOT SAVED -- PRESS SAVE TO KEEP CHANGES” appears. If you proceed to exit without saving, the FNB connection you selected will not be implemented.
5. Use the arrow keys to highlight
RETURN and press the Return key.

Ring Map Configuration Screen Fields
The following information briefly explains each Ring Map Configuration Screen field.
FDDI Address
Displays the address of the module. The format of this address (either MAC or Canonical) is determined by the value you select in the Address Mode field.
MAC Count
Displays the number of MACs (Media Access Controllers) that ar e attached to the specified ring.
Current Ring Map
Identifies the ring (FNB-1 or FNB-2) on which a MAC for the specified module resides, and whether that MAC is located on the primary or secondary path of that ring. If an additional ring is attached to the specified module, the name of that additional ring appears as a command at the bottom of the screen.

Address Mode (Toggle)

The Ring Map
Space Bar to toggle to the desired value.
Displays a series of addresses in upstream/downstream order. These addresses, which represent each FDDI device attached to the ring, are arranged on the scr een to simulate the circular fashion of a ring. When first displayed, the station at the upper left corner of this map is your current station. The screen displays node class, node address, and twisted and/or wrapped conditions (T for twisted, W for wrapped). The following lists the node class possibilities:
NAS (Null Attached Station) Isolated station; station not connected to an FDDI
ring.
DAS (Dual Attached Station) Station that does not support M ports, but
connects directly to an FDDI primary and secondary ring using A and B ports.
DAC (Dual Attached Concentrator) Station that supports M ports and connects
directly to an FDDI primary and secondary ring using A and B ports.
SAS (Single Attached Station) Station that accesses the main ring through a
concentrator, creating a ring of trees topology.

Page 10
9F426-02 Module Specific Information
SAC (Single Attached Concentrator) Station that accesses the main ring through another concentrator and, in turn, allows the connection of more devices. SACs provide the same connections as DACs, without attaching to the dual ring.
NAC (Null Attached Concentrator) Isolated concentrator; concentrator not connected to an FDDI ring.
While the map is updated, for example, during a ring topology change, the screen may show ??-??-??-??-??-?? to illustrate an undetermined address.
The Ring Map display stops at the first occurrence of an undetermined address,
NOTE
and does not display any known information beyond this point.
To view details of a listed ring map address, use the arrow keys to highlight that address and press the
Return key. The Ring Map Node Screen (9F426-02 FDDI
Switch Module), Figure 4, appears.

Ring Map Screen Commands

RETURN
Closes the Ring Map Screen, and returns you to the FNB Configuration Menu.
