Chapter 35

Adding Local Controllers

This chapter explains how to expand your network by adding a local controller to a master controller configuration. Typically, this is the first expansion of a network with just one controller (which is a master controller). This chapteris a basic discussion of creating master-local controller configurations. More complicated multi-controller configurations are discussed in other chapters.

This chapterdescribes the following topics:

•"Moving to a Multi-Controller Environment" on page 666

•"Configuring Local Controllers" on page 664

Configuring Local Controllers

This section highlights the difference in configuration for both of these scenarios.

The steps involved in migrating from a single to a multi-controller environment are:

1.Configure the role of the local controller to local and specify the IP address of the master.

2.Configure the layer-2 / layer-3 settings on the local controller (VLANs, IP subnets, IP routes).

3.Configure as trusted ports the ports the master and local controller use to communicate with each other.

4.For those APs that need to boot off the local controller, configure the LMS IP address to point to the new local controller.

5.Reboot the APs that are already on the network, so that they now connect to the local controller.

These steps are explained below.

You configure the role of a controller by running the initial setup on an unconfigured controller, or by using the WebUI, Controller Wizard, or CLI on a previously-configured controller.

Using the Initial Setup

Initial setup can be done using the browser-based Setup Wizard or by accessing the initial setup dialog via a serial port connection. Both methods are described in the Dell PowerConnect W-SeriesArubaOS Quick Start Guide and are referred to throughout this chapteras “initial setup.”

The initial setup allows you to configure the IP address of the controller and its role, in addition to other operating parameters. You perform the initial setup the first time you connect to and log into the controller or whenever the controller is reset to its factory default configuration (after executing a write erase, reload sequence).

When prompted to enter the controller role in the initial setup, select or enter local to set the controller operational mode to be a local controller. You are then prompted for the master controller IP address. Enter the IP address of the master controller for the WLAN network. Enter the preshared key (PSK) that is used to authenticate communications between Dell controllers.

NOTE: You need to enter the same PSK on the master controller and on the local Dell controllers that are managed by the master.
