The Vigor 2832 features a hugely flexible VLAN system. In its simplest form, each of the four Gigabit LAN ports can be isolated from each other, for example to feed different companies or departments but keeping their local traffic completely separated. For more sophisticated scenarios, the Vigor 2832 includes tagged VLANs (802.1q) whereby data is marked with a VLAN identifier. This identifier can be read by an onward Ethernet switch and directed to specific ports or just passed to the LAN for specific VLAN clients to pick up; priorities can also be applied for LAN-side QoS.
