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.

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.

9F426-03 Module Specific Information

• 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.

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

NOTE

and does not display any known information beyond this point.

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.

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.

9F426-03 Module Specific Information

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.

Switch Configuration Screen Fields

The following information briefly explains each Switch Configuration Screen
field.

Type of STA (Toggle)

Allows you to set the method that bridges use to decide which bridge is the
controlling (Root) bridge when two or more bridges exist in parallel (Spanning
Tree Algorithm). Press the Space Bar to toggle to the desired value. Valid types
are:

• DEC

• IEEE

• NONE ( default )

MAC Address

Lists the hardware address of each listed interface.

9F426-03 Module Specific Information

State

Displays the current state of each listed interface. The possible interface states
include:

Disabling: Management has disabled this interface. No traffic can be received

or forwarded while the interface is disabled.

Learning: The bridge is learning this interface’s network addresses. The

bridge enters the learning state when the Transparent Database is
created (during start-up or after being deleted), or when the
Spanning Tree Algorithm detects a network topology change.

Listening: The bridge is not adding information to the Transparent Database.

The bridge is monitoring BPDU traffic while preparing to move
from the learning to the forwarding state.

Forwarding: The bridge is on-line and this interface is forwarding traffic.

Blocking: This interface will not forward any traffic through the bridge.

Status (Toggle)

Allows you to set the forwarding status of the listed interface. Press the Space Bar
to toggle to the desired value. Valid values are:

• ENABLED ( default )

• DISABLED

Full Duplex Configuration Screen Fields

The following information briefly explains each Full Duplex Configuration Screen
field.

OPERATION MODE (Toggle)

Lets you determine whether the specified port will transmit and receive data
separately or simultaneously. You can set this field to one of the following values:

• FULL DUPLEX - The port can transmit and receive data at the same time.

Therefore, the port is running at 200 Mbps.

• STANDARD FDDI (default) - The port can either transmit data or receive data,

but not both at the same time. Therefore, the port is running at 100 Mbps.

LINK STATUS

Indicates whether there is a physical connection from this port to another device.
One of the following values appears:

9F426-03 Module Specific Information

• Link - There is a link signal present; there is a valid physical connection from

this port to another device.

• No Link - There is no link signal present; there is no valid physical connection

from this port to another device.

PORT STATUS

Indicates whether the port has been turned on or off administratively. You will see
one of the following values:

• ENABLED - The port is turned on administratively.

• DISABLED - The port is turned off administratively.

SET ALL PORTS (Toggle)

Allows you to set all the FDDI ports to either FULL DUPLEX or STANDARD
FDDI at one time.

• FULL (default)

• STANDARD
