AIX UNIX: Enabling Jumbo Frames

To enable jumbo frames on an AIX UNIX system, you can follow these steps:

1. Determine the maximum transmission unit (MTU) size that is supported by your network. Jumbo frames are typically larger than the standard MTU size of 1500 bytes, so you will need to know the maximum MTU size that is supported by your network before you can enable jumbo frames.

2. Edit the /etc/hosts file and add the MTU size to the interface configuration for each network interface that will use jumbo frames. For example:

192.168.1.1      myhostname      myhostname.example.com   1500

Replace 192.168.1.1 with the IP address of the interface, and 1500 with the MTU size that you determined in step 1.

3. Restart the network interface to apply the changes. You can do this by running the following command:

ifconfig en0 down
ifconfig en0 up

Replace en0 with the name of the network interface that you want to restart.

4. Test the jumbo frames to make sure they are working properly. You can use the ping command with the -s option to test the jumbo frames. For example:

ping -s 1472 192.168.1.1

Replace 192.168.1.1 with the IP address of the network interface that you want to test.

You can find more information about configuring jumbo frames on AIX UNIX systems in the AIX documentation or by searching online.

Keep in mind that jumbo frames may not be supported by all network devices and may require special configuration on the network devices to work properly. You may need to consult the documentation for your network devices to find out how to configure them to support jumbo frames.
