wlan3> set dhcp=none
The Client Address Space value is set with the „dhcp.relay.dhcp_subnet‟ parameter in the „sys‟
interface. This value should be a class A, B, or, C subnet specified using CIDR notation as
shown in the example below.
> use sys
sys> set dhcp.relay.dhcp_subnet=192.168.5.0/24
The Base Value, which sets the IP address of client interfaces on a node, is set through the
„dhcp.relay.base‟ parameter in the „sys‟ interface. The example below shows the configuration
for a mesh cluster consisting of 3 nodes.
On the gateway:
> use sys
sys> set dhcp.relay.base=192.168.5.3
on the first repeater node:
> use sys
sys> set dhcp.relay.base=192.168.5.8
and on the second repeater node:
> use sys
sys> set dhcp.relay.base=192.168.5.13
Note that the value of the fourth octet increases by 5 for each node since that is the number of
client interfaces that each node has, and each interface requires one IP address.
Web GUI
DHCP relay mode can be enabled via the web interface on the “DHCP Relay” sub-tab under
the “DHCP” tab on the “System Parameters” page (see Figure 37). The external DHCP server
IP address, the Client Address Space parameter, and the Base Value can also be set on this
page. The DHCP role parameters for all interfaces can be set on the “DHCP” sub-tab under
the “DHCP” tab on the “System Parameters” page.
