Ring Map Conﬁguration Screen

The Ring Map Conﬁguration Screen (Figure 1), contains conﬁguration and

connection information and displays the topology of the FDDI rings connected to

the module.

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 on which a MAC for the speciﬁed module resides, and whether

that MAC is located on the primary or secondary path of that ring.

Address Mode (Toggle)

Allows you to select the format in which addresses appear on this screen. Press

the

Space Bar

to toggle to the desired value. The Address Mode possibilities are:

• MAC

• Canonical

FRONT PANEL x (Toggle)

Allows you to display information about the module’s front panel ports.

Choosing a Front Panel Port

To choose a front panel port:

1. Use the arrow keys to highlight the FRONT PANEL x ﬁeld (lower left corner

of screen).

2. Press the

Space

Bar

to toggle to the desired port.

3. Press the

Return

key.

9F426-03 Module Speciﬁc Information

The Ring Map

The Ring Map shows 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 node class possibilities are:

• 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.

• 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.

Displaying the Ring Map Node Screen

To display the Ring Map Node Screen (from the Ring Map Conﬁguration Screen),

use the arrow keys to highlight an address, then press the Return key. The Ring

Map Node Screen appears.

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

and does not display any known information beyond this point.

Ring Map Node Screen Fields

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 node’s nearest upstream neighbor.

Node Class

Displays the class (NAS, DAS, DAC, SAS, or SAC) of the selected node. For an

explanation of these class codes, see page 5.

MAC Count

Displays the number of MACs (Media Access Controllers) that are attached to the

speciﬁed ring.

Non-Master Count

Displays the number of A and B ports on the selected node.

Master Count

Displays the number of M ports controlled by the selected node.

Peer Wrap

Indicates whether a wrap condition exists on a port. A peer wrap does not occur

when the A or B port is attached to an M port.

Unattached Conc (DAC only)

Indicates whether the selected node has no active A or B port.

Twisted A-A

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

Twisted B-B

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

Synchronous Service

Indicates whether the selected node uses synchronous bandwidth which

guarantees a certain percentage of the total FDDI bandwidth for real-time

applications.

Rooted

Indicates whether the selected node has an active A or B port when one, and only

one, end of the ﬁber link connects to an M port.
