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
"/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.

-

Example: 1000Mbps Full-Duplex is set.

name="fjgi" parent="/pci@83,4000" unit-address="1" AutoNegotiation_A="On"
LinkSpeed=”100” DuplexCapbilities_A="Full" FlowControl_A="None";

name: In the above example, the driver name is "fjgi".

parent: 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".

unit-address: Please refer to the /etc/path_to_inst, and write the number (right number of

"/FJSV,pwga@..". In this example, unit-address value is "1".

3.

After 2, the fjgi.conf setting is reflected by reboot.

# /usr/sbin/shutdown -i6 -y -g0

4.3.2.1.3

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.

Add the following line to /etc/system file.

set fjgi:fjgi_jumbo=1

b.

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.

vi /etc/fjmtu.fjgiX

"X" is instance number. Instance number must be the same as /etc/hostname.fjgi* file's *.
