Changing the setting of FCode
This section explains how to change the communication mode settings of FCode with examples.
If using PCI card (PW008GE4/PW008GE5/PW008QG1), please refer to the User's guide attached with PCI
card.
It is needed when don't use autonegotiation for speed/duplex/flowcontrol or connecting partner cannot
support autonegotiation.
[FCode Force mode (Speed Fixed and disable autonegotiation) setting method]
Search for the device path of 'FJSV' or 'pwga' in the OK prompt screen.
Example
ok show-nets <Return>
a) /pci@83,2000/FJSV,pwga@1
b) /pci@1f,4000/network@1,1
q) NO SELECTION
Enter Selection, q to quit:
In this example, a) is the device path of the pwga (secondary LAN port)
With the following command, the device is specified.
ok cd /pci@83,2000/FJSV,pwga@1 <Return>
Implement the following commands, it will change from AutoNegotiation mode to Force mode.
This setting is invalid during OBP (Open Boot Prom). PW008GE4 (1000BASE-SX) can use only 3) speed
setting commands.
1) Role setting commands
slave-mode (slave)
2) Half Duplex setting commands
half-duplex (Half Duplex)
3) Speed setting commands

If you execute ndd command repeatedly, fjgi interface performance may drop.
The values of link_speed, link_mode, autonego, flow_control are effective, only when link_status
= 1. If link_status = 0, these values are invalid.
The values of lp_10fdx_cap, lp_10hdx_cap, lp_100fdx_cap, lp_100hdx_cap, lp_1000fdx_cap,
lp_1000hdx_cap,
lp_pauseTX,
communication is done without Autonegation or Autonegation has not been established.
The values set by ndd command are invalid after reboot.
Since a setup of the operation mode by the ndd command becomes effective per physical interface,
when IPv4/IPv6 interface, SNA/FNA interface or the VLAN interface is being used, those are also
changed simultaneously.
lp_pauseRX,
lp_autoneg_cap
(Force Speed: 100Mbps)
(Force Speed: 10Mbps)
are
effective,
only
when
