9.3.4 DHCP Deployment Considerations

Before defining an internal DHCP server configuration, refer to the following deployment guidelines to ensure the configuration
is optimally effective:
• DHCP option 189 is required when AP650 access points are deployed over a layer 3 network and require layer 3 adoption.
DHCP services are not required for AP650 access points connected to a VLAN that's local to the controller or service
platform.
• DHCP's lack of an authentication mechanism means a DHCP server cannot check if a client or user is authorized to use a
given user class. This introduces a vulnerability when using user class options. For example, if a user class is used to assign
a special parameter (for example, a database server), there is no way to authenticate a client and it's impossible to check
if a client is authorized to use this parameter.
• Ensure traffic can pass on UDP ports 67 and 68 for clients receiving DHCP information.
