Step 2: Configure SmartPath AP-2 and SmartPath AP-3.
1. Power on SmartPath AP-2 and log in through its console port.
2. Configure SmartPath AP-2 with the same commands that you used for SmartPath AP-1:
ssid employee
ssid employee security protocol-suite wpa-auto-psk ascii-key N38bu7Adr0n3
interface wifi0 ssid employee
cluster cluster1
cluster cluster1 password s1r70ckH07m3s
interface mgt0 cluster cluster1
3. (Optional) Change the name and password of the superuser.
admin superuser mwebster password 3fF8ha
4. Check that the channel ID for wifi1 and wifi1.1 is now 149.
show interface
If the channel ID for wifi1 and wifi1.1 is not 149, set it to 149 so that SmartPath AP-2 uses the same channel as
SmartPath AP-1 for backhaul communications.
interface wifi1 radio channel 149
Setting the channel for the parent interface (wifi1) sets it for all its subinterfaces. An interface in backhaul mode only
needs one subinterface, which by default is wifi1.1.
save config
exit
5. Repeat the above steps for SmartPath AP-3.
Step 3: Connect SmartPath AP-2 and SmartPath AP-3 to the network.
1. Place SmartPath AP-2 within range of its clients and within range of SmartPath AP-1. This allows SmartPath AP-1 and -2 to send
backhaul communications to each other wirelessly as a backup path in case either member loses its wired connection to the
network.
2. Connect an Ethernet cable from the PoE In port on SmartPath AP-2 to the network switch.
3. Power on SmartPath AP-2 by connecting it to a power source.
After SmartPath AP-2 finishes booting up (indicated when the Power LED changes from steady amber to steady green), it auto-
matically discovers another member of cluster1 (SmartPath AP-1). The two members use a preshared key based on their shared
secret (s1r70ckH07m3s) to authenticate each other and AES to encrypt wired backhaul communications and AES-CCMP to
encrypt wireless backhaul communications between themselves. You can tell when they have formed a cluster because the
Mesh LED changes its blinking pattern from a fast to slow.
4. Place SmartPath AP-3 within range of its wireless clients and one or both of the other cluster members.
5. Power on SmartPath AP-3 by connecting it to a power source.
After SmartPath AP-3 boots up, it discovers the two other members of cluster1 over a wireless backhaul link. The members
authenticate themselves and establish a security association for encrypting backhaul communications among themselves.
SmartPath AP-3 then learns its default route to the wired network from the other cluster members. If the other members send
routes with equal costs—which is what happens in this example—SmartPath AP-3 uses the first route it receives. When it
learns this route, it can communicate with the DHCP server to get an IP address for its mgt0 interface.
