Managing LAN Segments on a Tenant Site

A network on a tenant site is divided into multiple LAN segments to improve traffic management and security. A LAN segment is a small portion of a LAN that is used by a work group. A grouping of multiple LAN segments form a department. LAN segments are separated by a bridge, router, or a switch.

You can view and manage LAN segments from the Sites > Site Management > Site Name > LAN tab.

These topics describe how to manage LAN segments on a site.
