This appendix contains local management information that is specific to the
9E423-36 Ethernet Switch Module.
The 9E423-36 Ethernet Switch Module is a 37-port switching module with:
•36 front panel Ethernet ports
•1 Internal Network Bus (INB) backplane port
Each front-panel port of the 9E423-36 can be configured to operate in the Full
Duplex mode. This configuration allows each port to provide a full 20 Mbps of
bandwidth.

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:
•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.

NOTE
LINK STATUS (Read-only)
Indicates whether there is a physical connection from this port to another
10Base-T device. One of the following values appears:
•Link - There is a 10Base-T link signal present; there is a valid physical
connection from this port to another 10Base-T device.
•No Link - There is no 10Base-T link signal present; there is no valid physical
connection from this port to another 10Base-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.

Port Statistics Screen Fields
The following information briefly explains each Port Statistics Screen field.
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 a bad Cyclic Redundancy Check (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.

Displays the number of broadcasts received.
8
MULTICASTS (Read-only)
Displays the number of multicasts received.
LINK STATUS (Read-only)

•NETWORK is used for load sharing. At least two ports must be designated as
NETWORK to do load sharing.
USER connections.
SmartTrunk State (Read-only)
Displays the current operating state of the port:
NoneThe trunk is operating as a normal bridge port.
BlockingThe port is load sharing, but in the blocked mode. While the
module performs the function of determining if there is a
network loop, data is temporarily blocked on new SmartTrunk
ports and any port that becomes newly linked.
SmartTrunking The port is load sharing with other Network designated ports of
the same instance.
Instance (Read-only)
Identifies the ports that are grouped together to share traffic load (load sharing).
# STPorts (Read-only)

Displaying the SmartTrunk Ports
There are two SmartTrunk screens. Each screen can display up to 12 ports. The
NEXT and/or PREVIOUS command displays at the bottom of the screen,
allowing you to navigate to either the next or previous screen.

bottom of the first screen. In the second screen, the PREVIOUS command
displays.
To display the next screen, use the arrow keys to highlight NEXT. Press ENTER
and the next screen of entries displays.
