How to Set Parameter

The method of setting up of each parameter of the secondary LAN port (FJSV,pwga) shown in Table 4.1 is
explained. If using PCI card (PW008GE4/PW008GE5/PW008QG1), please refer to the User's guide
attached with PCI card.
1. Search /etc/path_to_inst file for a fjgi interface.
# grep fjgi /etc/path_to_inst <Return>
"/pci@83,4000/FJSV,pwga@1" 0 "fjgi"
2. The interface-related parameters should be written in the /platform/sun4us/kernel/drv/fjgi.conf file.
-
name="fjgi" parent="/pci@83,4000" unit-address="1" AutoNegotiation_A="On"
LinkSpeed="100" DuplexCapbilities_A="Full" FlowControl_A="None";
name:
parent:
unit-address: Please refer to the /etc/path_to_inst, and write the number (right number of
3. After 2, the fjgi.conf setting is reflected by reboot.
# /usr/sbin/shutdown -i6 -y -g0 <Return>

Caution

- Setting by fjgi.conf is necessary only when autonegation is not used for speed/duplex/flow or
connecting partner cannot support autonegotiation.
- Since a setup the operation mode by the fjgi.conf file becomes effective per physical interface,
when the VLAN interface is being used, a VLAN interface is also changed simultaneously.
4.3.2.2

Setting a JumboFrame

Use of JumboFrame makes it possible to expand the TCP/IP MTU size from 1500 to 9000. As the
per-packet transmission size is expanded, the number of packets processed becomes fewer and thus the CPU
load is reduced.
The procedure of setting JumboFrame is show below.
a.
set fjgi:fjgi_jumbo=1
b.
vi /etc/fjmtu.fjgiX
"X" is instance number. Instance number must be the same as /etc/hostname.fjgi* file's *.

Auto (Default)

Slave
Example: 1000Mbps Full-Duplex is set.
In the above example, the driver name is "fjgi".
The left-hand portion of the pathname, containing the words '/FJSV,gwga@' in
/etc/path_to_inst, is to be added here.
In this example, parent value is "/pci@83,4000".
"/FJSV,pwga@..". In this example, unit-address value is "1".
Add the following line to /etc/system file.
Create /etc/fjmtu.fjgiX file and write a MTU-size between 1500 to 9000. And reboot, TCP/IP
MTU-size will be set. If you don't create this file, TCP/IP MTU-size will be the default of 9000.
Value
Auto select Master or Slave by the
partner. (This can be set when
AutoNegotiation_A= On.)
Communicate by Master.
Communicate by Slave.
