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  
Configuration selection appeared at the bottom of the General Configuration  
Screen (as depicted in the SmartSwitch 9000 Module Local Management Users  
Guide). However, in recent versions of SmartSwitch 9000 Module Local  
Management, the FNB Configuration selection appears on the Module

9F426-02 Module Specific Information  
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  
modules 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 modules 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 (FNB-  
1 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 9000s  
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 are 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)  
Allows you to select the format in which addresses appear on this screen (either  
MAC or Canonical). Press the Space Bar to toggle to the desired value.  
The Ring Map  
Displays a series of addresses in upstream/ downstream order. These addresses,  
which represent each FDDI device attached to the ring, are arranged on the screen  
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.  
7
 
 
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,  
and does not display any known information beyond this point.  
NOTE  
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

RETURN  
Closes the Ring Map Screen, and returns you to the FNB Configuration Menu.  
SCROLL DOWN 1  
Allows you to rotate the station addresses in the ring, one clockwise position.  
SCROLL UP 1  
Allows you to rotate the station addresses in the ring, one counterclockwise  
position.  
When the ring map contains only one station, the Scroll Up 1 and Scroll Down 1  
commands do not appear.

9F426-02 Module Specific Information  
FNB 2 or FNB 1  
The Current Ring Map field identifies the ring (FNB-1 or FNB-2) on which a MAC  
for the specified module resides. If an additional ring is attached to the module,  
the name of that additional ring appears as a command. To view the ring map of  
the additional ring, use the arrow keys to highlight the name of the additional  
ring and then press the Return key.

The following information briefly explains each Ring Map Node Screen field.  
Address  
Displays the address of the selected node.  
Upstream Address  
Displays the address of the selected nodes nearest upstream neighbor.  
Node Class  
Displays the class (NAS, DAS, DAC, SAS or SAC) of the selected node. For an

Indicates whether the A port is connected to another A port.
