BCM SDK Module<br />

CLI interacts with the test module through ioctls . The BCM driver is a<br />
character driver and consists of two subsections (API and Linux Character Driver).<br />
The API has functions for configuring VLAN, Stack, Trunk etc. and various<br />
initialization routines. BCM Driver exports all these functions to the Linux kernel.<br />
The test module invokes these exported functions. You can invoke the BCM CLI at<br />
the command prompt. The CLI is a menu driven and self explanatory application.<br />
At the Linux prompt type bcm_appln to invoke the BCM CLI. You will see the<br />
following output on screen:<br />
[root@Linux /root]$bcm_appln<br />
