25.11.1 Overview

The Layer 2 relay blocking functionality only performs Layer 3 forwarding on the Switch. It does not perform Layer 2 forwarding. When this functionality is used, Layer 2 forwarding is not performed for any frames within the VLAN, including broadcast frames and multicast frames.

This functionality is useful for isolating communication between terminals, such as in a hotel or apartment building. It also assists IP address utilization when set to handle multiple terminals on a single VLAN.
