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)
