Command line
To define DHCP relay servers, use the dhcp-server command. For example:
1. Configure the LAN that DHCP clients will connect to, if it is not already configured:
digi.router> lan 1 ip-address 10.251.99.1
digi.router> lan 1 state on
For more information, see Configure a LAN.
2. Enable DHCP relay server:
digi.router> dhcp-server 1 state relay
By enabling DHCP relay, you are disabling the device's local DHCP server, and any IP range that
is configured will be ignored.
3. Define the IP address of the DHCP server that will serve as the primary DHCP relay server:
digi.router> dhcp-server 1 relay-server1 192.168.1.1
4. (Optional) Define the IP address of the DHCP server that will serve as the primary DHCP relay
server:
digi.router> dhcp-server 1 relay-server2 192.168.1.2
5. Save the configuration:
digi.router> save config
