Configuring a WLAN Controller
Cisco lightweight APs receive their configuration from the Wireless LAN
Controller, which must be configured first. Initial configuration of the lightweight
WLC can be done via command line using the console port or via
web browser using the service port. Subsequent configuration can be done
via:
■ IOS Command Line—Either by Telnet, SSH, or the console port.
■ Web browser—Using the WLC’s IP address and Internet Explorer.
■ Cisco Wireless Control System—For centralized configuration control.
You need to configure the WLC with information such as VLANs, SSIDs,
and security policies. It downloads a configuration to its associated APs, and
you can also configure, monitor, or reset individual APs through the web
browser of the WLC. Review the material at this link for screen shots and
WLC configuration information:

WLCs use several different types of physical and logical interfaces that are
described in Table 6-2.
Table 6-2 Wireless LAN Controller Interfaces
Interface Type Description
Service Port Used for out of band management and initial
setup. Must be a unique subnet. Not present on
the 2006 WLC.
Management Interface Used by the APs to find their WLC and associate
with it. One per WLC.
AP-Manager Interface Used for LWAPP traffic between controller and
APs. Can have multiple AP-Manager interfaces.
Virtual Interface IP address used for mobility group when
implementing layer 3 roaming.
User Interface Used to carry data traffic from users. One per
VLAN.
