Introduction

This appendix contains local management information that is speciﬁc to the

9F426-02 FDDI Switch Module.

Module Interfaces

The 9F426-02 FDDI Switch Module has seven interfaces. Table 1 lists the

identifying number, name, and description of each interface.

Use the numbers listed in Table 1 to conﬁgure the module’s default interface (see

General Conﬁguration Screen).

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.

Figure 1. FNB Conﬁguration Menu (9F426-02 FDDI Switch Module)

Use the arrow keys to highlight an option, and press the

Return

key. The selected

screen appears.

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 User’s

Guide). However, in recent versions of SmartSwitch 9000 Module Local

Management, the FNB Conﬁguration selection appears on the Module

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 (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 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

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 (NullAttached 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 Aand B ports.

• DAC(DualAttachedConcentrator) Stationthatsupports Mports andconnects

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.

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.

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.

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.

The Ring Map display stops at the ﬁrst occurrence of an undetermined address,

and does not display any known information beyond this point.

NOTE

When the ring map contains only one station, the Scroll Up 1 and Scroll Down 1

commands do not appear.
