Appendix

9E423-24 Module Speciﬁc

Information

Introduction

This appendix contains local management information that is speciﬁc to the 9E423-24

Ethernet Switch Module.

The 9E423-24 Ethernet Switch Module is a 25-port switching module with:

• 24 front panel Ethernet ports (2 RJ-71 Telco connectors)

• 1 Internal Network Bus (INB) backplane port

Each front-panel port of the 9E423-24 can be conﬁgured to operate in the Full Duplex

mode. This conﬁguration allows each port to provide a full 20 Mbps of bandwidth.

Modifying Fields and User Privileges

To modify ﬁelds on this module, you must have read-write or super-user privileges. If

you have read-only privileges, you can view information; however, you cannot

modify any ﬁelds. For more information about user privileges and community names,

see the

MMAC-Plus Module Local Management User’s Guide.

Full Duplex Conﬁguration Screen Fields

OPERATION MODE

(Modiﬁable) - This ﬁeld 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:

• STANDARD ENET - The port can either transmit data or receive data, but not both

at the same time. Therefore, the port is running at 10 Mbps (this is the default).

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

Therefore, the port is running at 20 Mbps.

To set one Ethernet port to Full Duplex (for example, port 1):

1. Use the arrow keys to highlight

STANDARD ENET

in the Operation Mode ﬁeld

(to the right of port 1).

2. Press the

Space

Bar

until

FULL DUPLEX

appears in the ﬁeld.

3. Use the arrow keys to highlight the

SAVE

command on the bottom line of the

screen.

4. Press the

Return

key.

To set all 24 Ethernet ports to Full Duplex:

1. Use the arrow keys to highlight the

SET ALL PORTS

ﬁeld.

2. Press the

Space

Bar

until you see

FULL

3. Use the arrow keys to highlight the

SAVE

command on the bottom line of the

screen.

4. Press the

Return

key.

LINK STATUS

(Read-only) - Indicates whether there is a physical connection from

this port to another 10 Base-T device. One of the following values appears:

• Link - There is a 10 Base-T link signal present; there is a valid physical connection

from this port to another 10 Base-T device.

• No Link - There is no 10 Base-T link signal present; there is no valid physical

connection from this port to another 10 Base-T device.

9E423-24 Module Speciﬁc Information

PORT STATUS

(Read-only) - 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.

Displaying Information About Other Ports

To display information about other ports:

1. Use the arrow keys to highlight

[1-12]

(for the ﬁrst 12 ports) or

[13-24]

(for the last

12 ports) at the bottom of the Full Duplex Conﬁguration Screen.

2. Press the

Return

key.

Enable or disable ports from the Bridge Conﬁguration screen.

NOTE

Appendix

Port Statistics Screen

The 9E423-24 Port Statistics Screen displays information and statistics about the

Port Statistics Screen Fields

PORT #

(Read-only) - Indicates the current port for which statistics are displayed.

OCTETS

(Read-only) - Displays the number of octets transmitted and received.

PACKETS

(Read-only) - Displays the number of packets transmitted and received.

TOTAL ERRORS

(Read-only) - Displays the total number of errors on this port.

COLLISIONS

(Read-only) - Displays the total number of collisions detected on this

port.

CRC/ALIGNMENT ERRORS

(Read-only) - Displays the number of packets with bad

Cyclic Redundancy Checks (CRC) that have been received from the network. The

CRC is a 4-byte ﬁeld in the data packet that ensures that the transmitted data that is

received is the same as the data that was originally sent. Alignment errors are due to

misaligned packets.

UNDERSIZE PACKETS

(Read-only) - Displays the number of packets received

whose size was less than the minimum Ethernet frame size of 64 bytes, not including

preamble.

OVERSIZE PACKETS

(Read-only) - Displays the number of packets received whose

size exceeded 1518 data bytes, not including preamble.

FRAGMENTS

(Read-only) - Displays the total number of packets received that were

not an integral number of octets in length or that had a bad Frame Check Sequence

(FCS), and were less than 64 octets in length (excluding framing bits but including

FCS octets).

JABBERS

(Read-only) - Displays the total number of packets received that were

longer than 1518 octets (excluding framing bits, but including Frame Check Sequence

(FCS) octets), and were not an integral number of octets in length or had a bad Frame

Check Sequence.

BROADCASTS

(Read-only) -

Displays the number of broadcasts received.

MULTICASTS (Read-only) - Displays the number of multicasts received.

LINK STATUS (Read-only) - Displays one of the following values:

• Link

• No Link

• N/A

Appendix

PORT TYPE (Read-only) - Displays one of the following values:

• AUI

• BNC

• EPIM-x

• MMF SMA

• MMF ST

• RJ45

• RJ71

• SMF ST

PORT STATUS (Read-only) - Indicates the administrative status of the selected port.

Possible values are ENABLED and DISABLED.

APPLICATION (Read-only) - Displays BRIDGING, indicating that the port is

operating as a bridge with a high-speed backbone connection.

OPERATION MODE (Read-only) - Displays one of the following values:

• STANDARD ENET - The port can either transmit data or receive data, but not both

at the same time. Therefore, the port is running at 10 Mbps.

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

Therefore, the port is running at 20 Mbps.

PORT # (Modiﬁable) - Selects the port for which statistics are to be displayed.

Displaying Statistics for Another Port

To display statistics for another port:

1. Use the arrow keys to highlight the Port # ﬁeld at the bottom of the screen.

2. Press the Space Bar to increment (or press the Backspace key to decrement) the

port number.

3. Press the Return key (neither the read-only Port # ﬁeld nor the statistics will

change until you press the Return key).
