1. IFIP-UNU ADVANCED COURSE ON NETWORKING AND SECURITY Module II-Wireless Communications Section 5
Access Points

2. Overview
This module covers basic access point (AP) installation and configuration. An access point acts as a communication hub for wireless network users. An access point can link wired and wireless networks together. The goal of this module is to get the AP configured and communicating with clients and other APs. It is important to keep the configuration simple until connectivity is achieved. Later in this module, more detailed port configurations and services will be covered

3. Learning Objectives Demonstrate the proper AP setup and connection

50. Proxy Mobile IP

51. Proxy Mobile IP Devices
A visiting client device that can associate to an AP. It does not need any special proxy Mobile IP software.
An AP with proxy Mobile IP enabled.
An authoritative AP on your network supporting proxy Mobile IP. The authoritative AP uses a subnet map to keep track of the home agent information for all visiting client devices.
A home agent. The home agent is a router on the visiting client’s home network that serves as the anchor point for communication with the AP and the visiting client. The home agent tunnels packets from a correspondent node on the Internet to the visiting client device.
A foreign agent. The foreign agent is a router on your network that serves as the point of attachment for the visiting client device when it is on your network, delivering packets from the home agent to the visiting client

52. Proxy Mobile IP

53. Proxy Mobile IP SA Bindings

54. Proxy Mobile IP Caveats
You can enable proxy Mobile IP only on root APs.
APs should be configured with gateway addresses.
The foreign and home agents must reside on the network gateways where you want to support proxy Mobile IP.
If your authoritative APs receive their IP addresses through DHCP, use the access point host names to specify the AAPs in the proxy Mobile IP configuration.
Proxy Mobile IP does not support broadcast and multicast traffic for visiting clients.
To use Proxy Mobile IP with DHCP clients, disable Media Sense on the client.
Does not support VLANs.

55. Proxy Mobile IP Statistics

56. QoS

57. QoS Configuration WLAN QoS differs from QoS on other Cisco devices:
Does not classify packets
Do not match packets using ACLs
Do not support ISL
Difference is most notable on busy networks.
You should be familiar with your network traffic before configuring QoS.
QoS does not create additional bandwidth.

65. Summary
A variety of tools are available to configure an AP. The Web browser is usually the easiest way to configure an AP. The 1100 and 1200 also can be configured via Cisco IOS. Future APs will also support Cisco IOS.
