Virtual LANs

Adding Virtual LAN (VLAN) support to a Layer 2 switch offers some of the benefits of both bridging and routing. Like a bridge, a VLAN switch forwards traffic based on the Layer 2 header, which is fast. Like a router, it partitions the network into logical segments, which provides better administration, security and management of multicast traffic.

A VLAN is a set of end stations and the switch ports that connect them. You can have many reasons for the logical division, for example, department or project membership. The only physical requirement is that the end station, and the port to which it is connected, both belong to the same VLAN.

Each VLAN in a network has an associated VLAN ID, which appears in the IEEE 802.1Q tag in the Layer 2 header of packets transmitted on a VLAN. An end station may omit the tag, or the VLAN portion of the tag, in which case the first switch port to receive the packet may either reject it or insert a tag using its default VLAN ID. A given port may handle traffic for more than one VLAN, but it can only support one default VLAN ID.

Two features let you define packet filters that the switch uses as the matching criteria to determine if a particular packet belongs to a particular VLAN.

The IP-subnet Based VLAN feature lets you map IP addresses to VLANs by specifying a source IP address, network mask, and the desired VLAN ID.

The MAC-based VLAN feature let packets originating from end stations become part of a VLAN according to source MAC address. To configure the feature, you specify a source MAC address and a VLAN ID.

The Private Edge VLAN feature lets you set protection between ports located on the switch. This means that a protected port cannot forward traffic to another protected port on the same switch.

The feature does not provide protection between ports located on different switches.
