This switch provides a broad range of features for Layer 2 switching and Layer 3 
routing. It includes a management agent that allows you to configure the features 
listed in this manual. The default configuration can be used for most of the features 
provided by this switch. However, there are many options that you should configure 
to maximize the switch’s performance for your particular network environment.
