Layer 2 Tunneling and Filtering

This ExtremeXOS feature introduces the ability to tunnel and filter Layer 2 PDUs. Tunneling allows you to send Layer 2 PDUs across a service provider network, and be delivered to remote switches. It is useful when a network includes remote sites that are connected through a service provider network. Using tunneling, you can make the service provider network transparent to the customer network.

Filtering prevents Layer 2 PDUs from being received on a port.
