Chapter 11: Deployment Examples CLI

11.2 Example 2: Deploying a Cluster

Building on "Deploying a Single SmartPath AP" in Section 11.1, the office network has expanded and requires more SmartPath

APs to provide greater coverage. In addition to the basic configuration covered in the previous example, you configure all three

SmartPath APs to form a cluster within the same Layer 2 switched network. The following are the configuration details for the

cluster:

• Cluster name: cluster1

• Preshared key for cluster1 communications: s1r70ckH07m3s

NOTE: The security protocol suite for cluster communications is WPA-AES-psk.

SmartPath AP-1 and -2 are cabled to a switch and use the native ("untagged") VLAN for wired backhaul communications. They

communicate with each other over both wired and wireless backhaul links, the wired link taking precedence. However, SmartPath

AP-3 only communicates with SmartPath AP-1 and -2 over a wireless link (see Figure 2). Because SmartPath AP-1 and -2 connect

to the wired network, they act as portals. In contrast, SmartPath AP-3 is a mesh point.

SmartPath AP-1 and SmartPath AP-2 are

portals and use both wired and wireless

backhaul methods to communicate with

each other. SmartPath AP-3 is a mesh

point, using only a wireless connection

for backhaul communications with the

other two cluster members.

Figure 11-3. Three SmartPath APs in a cluster.

NOTE: If all cluster members can communicate over wired backhaul links, you can then use both radios for access. The wifi0 inter-

face is already in access mode by default. To put wifi1 in access mode, enter this command: interface wifi1 mode access. In

this example, however, a wireless backhaul link is required.

Step 1: Configure SmartPath AP-1

1. Using the connection settings described in the first example, log in to SmartPath AP-1.

2. Configure SmartPath AP-1 as a member of “cluster1” and set the security protocol suite.
