3.3 Operation Mode Setup
This section explains how to edit the fjgi.conf configuration file or issue a command to
change the operation mode of the FUJITSU PCI GigabitEthernet interface. The operation mode
can be changed with the following:
●
The fjgi.conf file
● JumboFrame Setup
●
The ndd Utility
●
FCode Settings
3.3.1 The fjgi.conf File
About speed/duplex/flowcontrol, it recommends carrying out default operation (automatic
setup by Auto-Negotiation). Usually, a setup of a fjgi.conf file is unnecessary.
It is a case as shown in the following examples that a setup of a fjgi.conf file is needed.
Example
● When connection partner equipment is not supporting Auto-Negotiation
In this case, please let mode of operation in agreement with self-equipment and
connection place partner equipment.
● Although Auto-Negotiation is used, when it is necessary to make only a specific
setting value into a different value from a default value (for example, when you
want to set speed as 100Mbps, in order to press down the CPU load by the network
low)
● When JumboFrame is used
It is also possible to set up except fjgi.conf. For details, please refer to "
3.3.2
JumboFrame Setup ".
The following table provides descriptions of the parameters used in the fjgi.conf file
to configure the GigabitEthernet interface.
When editing the fjgi.conf file, please review the
[Caution] items below.
