priority over other traffic, such as data. Administrators also use VLANs to protect network resources. Traffic sent by authenticated clients might be assigned to one VLAN, while traffic sent from unauthenticated clients might be assigned to a different VLAN that allows limited network access. When one host in a VLAN sends a broadcast, the switch forwards traffic only to other members of that VLAN. For traffic to go from a host in one VLAN to a host in a different VLAN, the traffic must be forwarded by a layer 3 device, such as a router. VLANs work across multiple switches and switch stacks, so there is no requirement for the hosts to be located near each other to participate in the same VLAN. NOTE: PowerConnect 7000 Series switches support VLAN routing. When you configure VLAN routing, the switch acts as a layer 3 device and can forward traffic between VLANs. For more information, see . Each VLAN has a unique number, called the VLAN ID. The PowerConnect 7000 Series switches support a configurable VLAN ID range of 2-4093. A VLAN with VLAN ID 1 is configured on the switch by default. You can associate a name with the VLAN ID. In a tagged frame, the VLAN is identified by the VLAN ID in the tag. In an untagged frame, the VLAN identifier is the Port VLAN ID (PVID) specified for the port that received the frame. For information about tagged and untagged frames, see "VLAN Tagging" on page 575. The PowerConnect 7000 Series switches support adding individual ports and Link Aggregation Groups (LAGs) as VLAN members. Figure 21-1 shows an example of a network with three VLANs that are department-based. The file server and end stations for the department are all members of the same VLAN. 572 Configuring VLANs
