Bridging: Enterprise style

The enterprise style bridging configuration is designed to provide basic bridging functionality for consumers of Ethernet-based services. The isolation of services for different customers on a single port is not required, because each port is typically connected to a host or is providing a trunk to another switch.

With the enterprise style bridging configuration, logical interfaces are placed into Layer 2 mode by specifying ethernet-switching as the interface family. Without using flexible Ethernet services, ethernet-switching can only be configured on a single logical unit, unit 0. You cannot bind a VLAN ID to unit 0, because these interfaces operate either in trunk mode, which supports traffic with various VLAN tags, or in access mode, which supports untagged traffic.
