Ethernet Switching
The Ethernet Switching Feature License enables the usage of MAC level switching on an Nimbra 600 series 8 x Gigabit Ethernet Access Module. The basic Ethernet Transport Service (ETS™) provides a high QoS transport service that transports Ethernet packets in secure, bandwidth configurable, point-to-point or point-to-multipoint channels with no packet loss and with very low packet jitter. The Ethernet Switching Feature License enhances this functionality with IEEE802.1D/Q multipoint-to-multipoint MAC layer switching. All Metro Ethernet Forum service types are thus supported.
