Introduction
This appendix contains local management information that is specific to the
9G426-02 Ethernet Module.
The 9G426-02 Ethernet Module is a 3-port switching module with:
• 2 front panel gigabit Ethernet ports
• 1 Internal Network Bus (INB) backplane port
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.

9G426-02 Module Specific Information
General Configuration Screen Fields
The following information briefly explains each General Configuration Screen
field.
Module Serial #
Displays the serial number of the selected module.
Module Board Revision
Displays the version number of the selected module.
FLASH Memory
Displays the amount (megabytes) of flash memory in the selected module.
Module Date
Contains a value that the module recognizes as the current date. To enter a new
date, highlight the field and enter the date in MM/DD/YYYY format. The month
and day portion of the date must include two digits. Therefore, enter a leading
zero for months January through September, and for dates less than 10. For
example, for June 4, 1996, enter 06/04/1996 (slashes are optional). If you do not
enter slashes to separate the month, day, and year values, the first eight digits you
enter in this field represent an entry (i.e., 06041996).
NOTE
Module Time
Contains a value that the module recognizes as the current time. To enter a new
time, highlight the field and enter the time in HH:MM:SS format. Notice that
there is no AM/PM indicator. Time should be entered based upon a 24 hour clock.
For 4:07 p.m., enter 16:07:00 (colons are optional). If you do not enter colons to
separate the hours, minutes, and seconds values, the first six digits you enter in
this field represent an entry (i.e., 160700). For 6:12 a.m., enter 6:12:00 or 061200.
The module’s default date and time settings are indeterminate. The internal calendar and
clock begin running as soon as you install the module.
Screen Refresh Time
Contains the rate at which the module’s screens are updated. This setting
determines how frequently (in seconds) information is updated on the screen. To
enter a new refresh rate, highlight the field and enter a number. The default
refresh rate is 3 seconds. The range is 3 - 99 seconds.

9G426-02 Module Specific Information
Screen Lockout Time
Contains the maximum number of minutes that the Local Management
application will display a module’s screen while pending input or action from a
user. For example, if you enter 5 in this field, users will have up to five minutes to
respond in some fashion to each of the specified module’s Local Management
screens. In our example, after five minutes of “idleness” (no input or action), the
Local Management application terminates the session on the selected module and
the Slot Selection Screen reappears. To enter a new lockout time, highlight the
field and enter a number. The default lockout time is 15 minutes. The range is 1 30 minutes.
Host IP Address
Contains the Internet Protocol address currently assigned to the selected module.
Set this field according to your network requirements. Highlight the Host IP
Address field and enter the desired IP address using dotted decimal notation (4
decimal values between 1 and 255 separated by periods) as follows:
255.255.255.255
(255 is the maximum number that you can enter in any of the four segments.
Default = 0.0.0.0 .) This address can be used by any of the system interfaces on the
module.
Subnet Mask
Contains the subnet mask for the selected module. A subnet mask “masks out”
the network bits of the IP address by setting the bits in the mask to 1 when the
network treats the corresponding bits in the IP address as part of the network or
subnetwork address, or to 0 if the corresponding bit identifies the host. The
default subnet mask uses the first two portions of the IP address to identify the
network id, leaving the rest of the IP address to identify specific nodes. To enter a
new subnet mask, highlight the field and enter a new value using dotted decimal
notation (4 decimal values between 1 and 255 separated by periods) as follows:
255.255.255.255
(The Subnet Mask field defaults to the natural mask value, based on the IP
Address that you entered for the device.)

Port Statistics Screen Fields
The following information briefly explains each Port Statistics Screen field.
PORT #
Indicates the current port for which statistics are displayed.
OCTETS
Displays the number of octets transmitted and received on the port.
PACKETS
Displays the number of packets transmitted and received on the port.
TOTAL ERRORS
Displays the total number of errors on the port.
9G426-02 Module Specific Information
COLLISIONS
Displays the total number of collisions detected on this port.
CRC/ALIGNMENT ERRORS
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
Displays the number of packets received whose size was less than the minimum
Ethernet frame size of 64 bytes, not including preamble.
OVERSIZE PACKETS
Displays the number of packets received whose size exceeded 1518 data bytes,
not including preamble.
FRAGMENTS
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
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
Displays the number of broadcasts received.

MULTICASTS
Displays the number of multicasts received.
LINK STATUS
Indicates whether there is a physical connection from this port to another device.
One of the following values appears:
• 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 TYPE
Displays the value GPIM-F01, which is an Ethernet Gigabit Fiber Channel 1 Gig,
MMF, SC
NOTE
PORT STATUS
Indicates the administrative status of the selected port. Possible values are:
• ENABLED - The port is turned on administratively
• DISABLED - The port is turned off administratively
Enable or disable ports from the Bridge Configuration screen.
APPLICATION
Displays BRIDGING , indicating that the port is operating as a bridge with a
high-speed backbone connection.
OPERATION MODE
Displays the value FULL DUPLEX . The port can transmit and receive data at the
same time. Therefore, the port is running at 1000 Mbps.
PORT # (Modifiable)
Selects the port for which statistics are to be displayed.
