3.3 Operation Mode Setup

2.The MTU size of TCP/IP is set up by creating /etc/fjmtu.fjgi* (notes) and describing MTU size in /etc/fjmtu.fjgi* in the form of the following between 1500 and 9000 and rebooting. When not specifying an MTU value as this file, it is set as a default value (except for a 9000Byte MAC header).

(Note) * expresses an instance number. An instance number should set up the value (the same as that of * of /etc/hostname.fjgi*) which surely corresponds.

Example of setting (when setting MTU size of fjgi0 to 8000)

# cat /etc/fjmtu.fjgi0 8000

#

3. Reboot the system.

[Method 3: How to specify by fjgi.conf]

When you set up MTU size separately by every interface, and when application does not refer to /etc/hostname.fjgi* (example . CF of PRIMECLUSTER, CIP function), please use this method.

This method can be used only in Solaris 9 or later, and when the following patch for PRIMEPOWER is applied.

In the case of Solaris 9 OS: 114994-13 or later

In the case of Solaris 10 OS: 120462-06 or later

1.Add fjgi_mtu parameter to fjgi.conf file. Specify the value like fjgi_mtu=8000 instead of the character string like fjgi_mtu="8000".

Example of file description (when setting MTU size of a specific interface to 8000) name="FJSV,pgtb" parent="/pci@15,2000" unit-address="1"

fjgi_mtu=8000;

2.Reboot the system.

●If JumboFrame support is enabled, the interface will be unable to transmit and receive data in IEEE802.3 format.

●In the case of a method 1 or a method 2, if two or more interfaces, or VLAN interfaces are installed, the JumboFrame setting applies to all interfaces.

●When the file transfer protocol (FTP) is used, set the MTU-size to 8232 or less.

●When using the JumboFrames function with the PW008GE5, PW0G8GE2, SE0X7GD1X, PW008QG1, SE0X7GQ1X or the PRIMEPOWER250/450 secondary LAN port, only use 1000Mbps mode.
