Autonomous Access Point Homepage



Express Setup

Initial configuration of access point: hostname, IP address, SNMP



Self Check

1. Name 3 methods of configuring an autonomousaccess point.

2. Identify 4 methods to discover the IP address of an

autonomous access point.

3. What type of devices can root devices acceptassociations from?



Centralized WLANConfiguration



Getting started

The bulk of the configuration tasks required to setup aCentralized WLAN solution are performed on theWireless LAN Controller.

Lightweight Access Points are designed to be zero

touch and are not directly configured by theadministrator.

The very basic configuration tasks required on the WLCare done via CLI, while more complex tasks are

completed after the web interface is accessible.



WLC and Lightweight AP Configuration

These are the basic steps to getting the controller andAPs online:

Have a DHCP server present so that the APs canacquire a network address.

Note: Option 43 is used if the APs reside in a different subnet.

Configure the WLC for basic operation.

Configure the switch for the WLC.

Configure the switch for the APs.

Register the lightweight APs to the WLCs.



Lightweight WLAN ControllerConfiguration

Initial setup

Command line via serial console

Ongoing configuration*

Web browser

Command line via serial console, Telnet,or SSH

Cisco WCS (optional)

*Requires IP address to be configured on controller

Switch configuration for WLC

The 802.1Q switch port configuration is:

interface GigabitEthernet1/0/1

description Trunk Port to Cisco WLCswitchport

trunk encapsulationdot1qswitchport trunk

allowed vlan2-4,60switchport mode trunk

no shutdown



Switch configuration for APs

This is an example VLAN interface configuration fromthe Catalyst 3750:

interface VLAN5

descriptionAP VLAN

ip address 10.5.5.1 255.255.255.0

This is an example switch port configuration from theCatalyst 3750:

interface GigabitEthernet1/0/22

descriptionAccess Port Connection to LWAPP AP

switchport access vlan 5

switchport mode access

no shutdown



AP Registration to WLC

As soon as the controller is activated, it starts listeningfor access points on all connected ports.

As it detects access points, it records their MACaddresses in its database.

The Radio Resource Management (RRM) function thenautomatically configures the access points to starttransmitting and start allowing clients to connectthrough the Cisco WLAN Solution.



Self Check

1. How are lightweight access points configured?

2. What methods can be used to configure the WLANcontroller?

3. Which WLAN controller interface is the onlyconsistently pingable interface from outside the WLC?

4. What mode should the switchport be in for connectionto the WLC?

5. What mode should the switchport be in for connectionto an access point?
