Appendix
9E312-12 Module Specific
Information
Introduction
This appendix contains local management information that is specific to the 9E312-12
Ethernet Switch Module.
The 9E312-12 Ethernet Switch Module is a 13-port switching module with:
• 12 front panel Ethernet ports
• 1 Internal Network Bus (INB) backplane port
Each port of the 9E312-12 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
PORT # (Read-only) - Displays the numbers for each of the Ethernet ports.
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 12 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.

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.
Enable or disable ports from the Bridge Configuration screen.

Port Statistics Screen Fields
PORT # (Read-only) - Indicates the current port for which statistics are displayed.
OCTETS (Read-only) - Displays the number of bytes transmitted and received.
PACKETS (Read-only) - Displays the number of frames 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.
Appendix
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.
LINK STATUS (Read-only) - Displays one of the following values:
• Link
• No Link
• N/A
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 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 Statistics Screen Commands
To display statistics for another port:
1. Use the arrow keys to highlight the PORT # command at the bottom of the screen.
2. Press the Space Bar to increment (or press the Delete 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).
To exit the Port Statistics screen:
Use the arrow keys to highlight RETURN and press the Return key.
