Pointing the CMAP to ZoneDirector

If you are deploying the access point to be managed by ZoneDirector, you must ensure

that the CMAP can report to its parent ZoneDirector device on the network. There are two

ways you can do this:

■ Use SSH to Set the ZoneDirector IP Address on the CMAP

■ Configure Option 43 on the DHCP Server (ZoneDirector Management Only)

15

Preparing for Installation

Pointing the CMAP to ZoneDirector

Use SSH to Set the ZoneDirector IP Address on the CMAP

You can use SSH to set the IP address of the ZoneDirector device that you want to use to

manage the CMAP. Before starting this procedure, you must obtain the IP address of the

ZoneDirector device to which you want to assign the CMAP.

To perform this procedure, you will need the following:

■ An administrative computer

■ An Ethernet cable

■ A Telnet or SSH (secure shell) client program

To set the ZoneDirector IP Address on the CMAP via SSH

1. Connect one end of the Ethernet cable to the administrative computer’s Ethernet port,

and then connect the other end to the CMAP’s Ethernet port.

2. Change the administrative computer’s IP address to the same subnet as the CMAP.

The AP’s default IP address is 192.168.100.2.

3. Start the Telnet or SSH client program on the administrative computer.

4. Log onto to the AP via Telnet or SSH using the following logon details:

•User name: super

•Password: sp-admin

5. When command prompt appears, enter the following command:

set director ip {ip-address}

where {ip-address} is the IP address of the ZoneDirector to which you want to

assign the CMAP.

The following message appears, which indicates that you have assigned the

ZoneDirector IP address:

Please reboot for this change to take effect.

6. Reboot the CMAP.

7. Log onto the command prompt again, and then enter the following command:

get director info

The command prompt displays the IP address of the ZoneDirector device that is

managing the CMAP.

8. Verify that this IP address is the same IP address that you set in Step 5

.

You have completed the setting the ZoneDirector IP address via SSH.

16

Preparing for Installation

Pointing the CMAP to ZoneDirector

Configure Option 43 on the DHCP Server (ZoneDirector

Management Only)

You can configure the DHCP server on your CMTS backbone to ensure that the CMAP will

successfully discover its parent ZoneDirector on the network.

To customize your DHCP server, you need to configure DHCP Option 43 (043 Vendor

Specific Info) with the IP address of the ZoneDirector device on the network. When an

access point requests an IP address, the DHCP server will send a list of ZoneDirector IP

addresses to the access point. If there are multiple ZoneDirector devices on the network,

the access point will automatically select a ZoneDirector to register with from this list of IP

addresses.

NOTE: The following procedure describes how to customize a DHCP server running on

Microsoft Windows. If your DHCP server is running on a different operating system, the

procedure may be different.

The procedure for configuring Option 43 on your DHCP server depends on whether both

ZoneDirector and FlexMaster exist on the network, and whether you want to add the DHCP

subcode for ZoneDirector.

If Only ZoneDirector Exists on the Network (No ZoneDirector Subcode)

1. From Control Panel > Windows Administrative Tools, open DHCP, and then select the

DHCP server you want to configure.

2. If the Scope folder is collapsed, click the plus (+) sign to expand it.

3. Right-click Scope Options, and then click Configure Options. The General tab of the

Scope Options dialog box appears.

4. Under Available Options, look for the 43 Vendor Specific Info check box, and then

select it.

5. Under Data Entry, position the cursor in the ASCII text area, and then type the IP

address of the ZoneDirector device. In the figure below, the IP address of the

ZoneDirector device is 192.168.10.1.
