•Linux:

#ifconfig ethN down

#ifconfig ethN up

Configuration

IRIX and Linux use different configuration tools.

IRIX Configuration

The configuration of the adapter is controlled by a number of parameters, which are discussed in the IRIX /etc/config/xgcmd.options file.

To change the configuration of your adapter, use the xgcmd command. For more information, see the xgcmd man page.

Linux Configuration

To change the configuration of your adapter, use the ethtool(8) command. For more information, see the ethtool(8) man page.

MTU Size Settings

The maximum transmission unit (MTU) size is controlled by the mtu mtu_size switch of the ifconfig command. The most common MTU sizes are 1500 bytes (standard-size Ethernet frames) and 9000 (jumbo Ethernet frames). The adapter supports an MTU size of up to 9600 bytes. Configuring the adapter to use jumbo frames can increase network throughput and reduce CPU load, but only if the network supports jumbo frames.

To configure the MTU size, follow these steps:

1.At the command prompt, enter the following command: netstat -i
