Interfaces
3. Enable the DHCP server for an existing LAN. For example, to enable the DHCP server for a LAN
named my_lan:
(config)> network interface my_lan ipv4 dhcp_server enable true
(config)>
See Configure a LAN
4. (Optional) Set the amount of time that a DHCP lease is valid:
(config)> network interface my_lan ipv4 dhcp_server lease_time value
(config)>
where value is any number of weeks, days, hours, minutes, or seconds, and takes the format
number{w|d|h|m|s}.
For example, to set network interface my_lan ipv4 dhcp_server lease_time to ten minutes,
enter either 10m or 600s:
(config)> network interface my_lan ipv4 dhcp_server lease_time 600s
(config)>
5. (Optional) Set the lowest IP address that the DHCP server will assign to a client. This value
represents the low order byte of the address (the final triplet in an IPv4 address, for example,
192.168.2.xxx). The remainder of the IP address will be based on the LAN's static IP address as
defined in the address parameter.
(config)> network interface my_lan ipv4 dhcp_server lease_start num
(config)>
Allowed values are between 1 and 254, and the default is 100.
6. (Optional) Set the highest IP address that the DHCP server will assign to a client:
(config)> network interface my_lan ipv4 dhcp_server lease_end num
(config)>
Allowed values are between 1 and 254, and the default is 250.
7. Optional DHCP server settings:
a. Click to expand Advanced settings.
b. Determine how the DHCP server should broadcast the gateway server:
(config)> network interface my_lan ipv4 dhcp_server advanced gateway
value
(config)>
where value is one of:
