Chapter 3 Setting Configuration Information
is set up automatically.
● When you use ndd command and you change mode of operation, please let mode of
operation in agreement with self-equipment and connection partner equipment. When
mode of operation is not in agreement with self-equipment and connection partner
equipment, it may not become a value as a link up is not carried out, or it cannot
communicate even if it carries out a link up, or mode of operation specified.
● Due to the ndd command specification, if two or more processes execute the ndd command
for same driver at the same time, the resulting value will be invalid.
● If the ndd command is issued repeatedly, the fjgi driver's performance may decrease.
● The link_speed, link_mode, autonego, and flow_control parameter values are valid
only when link_status = 1. If link_status = 0, these values are invalid.
● The
lp_1000fdx_cap, lp_1000hdx_cap, lp_pauseTX, lp_pauseRX, and lp_autoneg_cap
parameter values are valid only when Auto-Negotiation communication is successfully
established. The parameter values are invalid when Auto-Negotiation is disabled or
when Auto-Negotiation communication fails.
● The parameter values set by the ndd command become invalid after reboot.
● An ndd command made to a physical interface that is related to IPv4/IPv6 interface
and SNA/FNA interface will apply to both the physical interface and the VLAN
interface.
3.3.4 FCode Settings
By modifying FCode settings, the adapter communication mode can be changed. Changing the
FCode settings is possible on PW008GE4/PW0G8GE1/SE0X7GD2X/PW008GE5/PW0G8GE2/
SE0X7GD1X/PW008QG1/SE0X7GQ1X and the secondary LAN port of the PRIMEPOWER250/450.
Modifying FCode settings may be needed when Auto-Negotiation is not used for speed, duplex
setting, and flow control, or when the link partner does not support Auto-Negotiation.
FCode changes do not take effect after the OBP reset and netboot is completed.
[FCode Setting Example]
The following example describes how to disable Auto-Negotiation and set the communication
speed of an fjgi interface by modifying the FCode settings.
● Search for the device path for the GigabitEthernet interface at the ok prompt.
(Please refer to chapter 3.4 "Discernment of the GigabitEthernet Interface.)
example) ok show-nets
In above example, "a) /pci@1f,4000/FJSV,pgtb@5" represents a PW008GE5 interface.
● Select the device.
example) ok cd /pci@1f,4000/FJSV,pgtb@5
● Execute the following command to change the mode into Force mode (speed fixed,
