Chapter 13: Client IP Configuration
TR0153 Rev. E1 105
The Base Value, which sets the IP address of client access interfaces on an EnRoute500, is
set through the ‘dhcp.relay.base’ parameter in the ‘sys’ interface. The example below shows
the configuration for a mesh neighborhood consisting of 3 devices.
On the gateway:
> use sys
sys> set dhcp.relay.base=192.168.5.3
on the first repeater device:
> use sys
sys> set dhcp.relay.base=192.168.5.8
and on the second repeater device:
> use sys
sys> set dhcp.relay.base=192.168.5.13
Note that the value of the fourth octet increases by 5 for each device since that is the number
of client access interfaces that each device has, and each interface requires one IP address.
Web GUI
Centralized DHCP server 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 47). The external
DHCP server IP address, the gateway router address, the Client Address Space parameter,
and the Base Value can also be set on this page. The DHCP mode parameters for all client
access interfaces can be set on the “DHCP” sub-tab under the “DHCP” tab on the “System
Parameters” page. Set the DHCP mode to “central server” for all interfaces whose client
devices should receive addresses from the central DHCP server.
On the “System” tab of the “System” page, set the “L2 Emulation” to “enabled”.
