Dhcp Setup Using The Internal Dhcp Server - Extreme Networks Summit WM Technical Reference Manual

Configuration of Dynamic Host Configuration Protocol (DHCP)
Table 8: Use of DHCP (Continued)
Area Description of use for DHCP
C For AP deployment networks that are not in the same subnet as the Summit WM Controller there
needs to be some mechanism to allow the APs to find the Summit WM Controller across subnet. The
APs can use a static list of Summit WM Controllers to connect to or use DNS but by far the most
common method is to allow them to use DHCP option 78 to locate a service location protocol (SLP)
director agent that is generally hosted on the Summit WM Controller itself.
In addition, the APs themselves may also be addressed via DHCP in this area.
DHCP services for this area MUST be provided external to the Summit WM Controller.
D DHCP services in area D is for WLAN clients. A separate scope for each SSID is required.
DHCP services for this area are provided by default by the Summit WM Controller. DHCP services can
also be relayed to an external DHCP server.

DHCP setup using the internal DHCP server

For simple DHCP setups it is recommended to use the Summit WM Controller's built-in DHCP server.
The internal DHCP server is intended to provide WLAN clients with IP addresses. The internal DHCP
server settings are available in the UI under WM-AD - Topology. This page allows for the configuration
of the following options for DHCP:

The major benefit of using the internal DHCP server is that all DHCP messages from clients are logged
and available in the GUI under Logs & Traces - DHCP messages.
For the inclusion of options that are not supported within this layout it is recommend to use DHCP
relay.
