Cisco Systems 3.2 manual Ports, Interfaces, and WLANs

Chapter 3 Configuring Ports and Interfaces

Overview of Ports and Interfaces

WLANs

A WLAN associates a service set identifier (SSID) to an interface. It is configured with security, quality of service (QoS), radio policies, and other wireless network parameters. Up to 16 access point WLANs can be configured per controller.

Note Chapter 6 provides instructions for configuring WLANs.

Figure 3-4illustrates the relationship between ports, interfaces, and WLANs.

Figure 3-4 Ports, Interfaces, and WLANs

As shown in Figure 3-4, each controller port connection is an 802.1Q trunk and should be configured as such on the neighbor switch. On Cisco switches, the native VLAN of an 802.1Q trunk is an untagged VLAN. Therefore, if you configure an interface to use the native VLAN on a neighboring Cisco switch, make sure you configure the interface on the controller to be untagged.
