Cisco Wireless LAN Controller Configuration Guide

OL-13826-01

Chapter 1 Overview

Network Connections to Cisco Wireless LAN Controllers

This means that when sufficient controllers are deployed, should one controller fail, active access point

client sessions are momentarily dropped while the dropped access point associates with an unused port

on another controller, allowing the client device to immediately reassociate and reauthenticate.

Network Connections to Cisco Wireless LAN Controllers

Regardless of operating mode, all controllers use the network as an 802.11 distribution system.

Regardless of the Ethernet port type or speed, each controller monitors and communicates with its

related controllers across the network. The following sections give details of these network connections:

• Cisco 2000 and 2100 Series Wireless LAN Controllers, page 1-19

• Cisco 4400 Series Wireless LAN Controllers, page 1-20

Note Chapter 3 provides information on configuring the controller’s ports and assigning interfaces to them.

Cisco 2000 and 2100 Series Wireless LAN Controllers

Cisco 2000 and 2100 series controllers can communicate with the network through any one of their

physical data ports, as the logical management interface can be assigned to one of the ports. The physical

port descriptions follow:

• Up to four 10/100BASE-T cables can plug into the four back-panel data ports on the 2000 series

controller chassis.

• Up to six 10/100BASE-T cables can plug into the six back-panel data ports on the 2100 series

controller chassis. The 2100 series also has two PoE ports (ports 7 and 8).

Figure 1-4 shows connections to the 2000 and 2100 series controllers.
