Jumbo Frames Support

ITI-5100G/GF adapters support Jumbo Frames--frames of up to 9,000 bytes that are sent between servers that have ITI-5100G/GF adapters and switches that support Jumbo Frames. Host CPU utilization is significantly reduced and network throughput is enhanced by sending 9,000 byte frames rather than the standard 1,500 byte Ethernet frames.

Overview

A single ITI-5100G/GF adapter on a server can support standard Ethernet frames as well as Jumbo Frames. Jumbo Frames are only sent between servers that have ITI-5100G/GF adapters. Standard Ethernet frames are used between servers that have ITI-5100G/GF Adapters and all other Ethernet devices.

Note: Not all network switches support passing Jumbo Frames. Check with your switch manufacturer for confirmation of Jumbo Frame support.

Configuring Jumbo Frames Support

To configure Jumbo Frame support, perform the following procedure:

1.Create the /etc/jumbo.alt <num> file.

2.Use your regular text editor to put the number “9000 " into the

/etc/jumbo.alt <num> file.

Put the number “9000 " in the file, without spaces or blank lines.

3.If you are finished with all optional configuration, reboot the system.

Changes to the optional configuration parameters (Jumbo Frame, or Dual Homing) do not take effect until you reboot the system. If you will be making changes to the other optional parameters during your configuration session, you should wait to reboot until those changes are complete.
