Chapter 1 Overview
Default Settings After Initial Switch Configuration
Default Settings After Initial Switch Configuration
The switch is designed for plug-and-play operation, requiring only that you assign basic IP information
to the switch and connect it to the other devices in your network. If you have specific network needs,
you can change the interface-specific and system-wide settings.
If you do not configure the switch at all, the switch operates with the default settings listed in Table 1-1.
This table lists the key software features, their defaults, and where to find more information about the
features.
For information about setting up the initial switch configuration and assigning basic IP information to
the switch, refer to the hardware installation guide.
