DHCP setup using the internal DHCP server
For simple DHCP setups it is recommended to use the Summit WM’s built-in DHCP server. 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.
C For AP deployment networks that are not in the same subnet as the Summit WM there needs to
be some mechanism to allow the APs to find the Summit WM across subnet. The APs can use a
static list of Summit WMs 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 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.
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. DHCP services can also
be relayed to an external DHCP server.
