A Virtual Local Area Network (VLAN) is a switched network that is logically segmented by function, area, or application without regard to the physical locations of the users. VLANs are a group of hosts or ports that can be located anywhere in a network but communicate as if they are on the same physical segment. VLANs help to simplify network management by letting you move a device to a new VLAN without changing any physical connections.
A tagged VLAN between a trunk port and a switch port contains the VLAN information in the Ethernet frame. An untagged VLAN sends traffic without the VLAN tag. A VLAN tag inserts information into Ethernet frames identifying which frame belongs to which VLAN. A trunk port is a port that handles multiple VLANs.
The Service Set Identifier (SSID) is a unique identifier that wireless clients can connect to or share among all devices in a wireless network. It is case-sensitive and must not exceed 32 alphanumeric characters.
The SSID Broadcast feature allows the SSID to be broadcasted on the network. This feature is enabled by default to make the network discoverable by wireless devices.
This article provides instructions on how to configure SSID-to-VLAN mapping on wireless access points.
