The basic procedure to change the default setting is that you have to delete the existing configuration
and reentering new configuration.
> home
↵
> dhcpserver config
↵
(displays the current DHCP server configuration)
> dhcpserver config flush
↵
(deletes current DHCP server settings)
> dhcpserver config confirm
↵
(confirm the previous action)
> config save
↵
(save the new configuration)
> dhcpserver config
↵
(displays the current DHCP server configuration. Should be empty.)
Now add the new settings for DHCP server.
>
dhcpserver config add subnet 10.0.0.0 netmask 255.255.255.0 {
range 10.0.0.A
10.0.0
.
B; default-lease-time C; max-lease-time D; option routers 10.0.0.1; option
domain-name-servers eee.fff.ggg.hhh, iii.jjj.kkk.lll; option domain-name “mmmm” }
↵
(A, B are integers in the range 2--255, C/D indicate time in seconds,eee.fff.ggg.hhh/iii.jjj.kkk.lll are IP
addresses of primary/secondary DNS, mmmm is domain name. All these values are assigned by your
service provider.)
>
dhcpserver config add subnet aaa.bbb.ccc.ddd netmask eee.fff.ggg.hhh { }
↵
(aaa.bbb.ccc.ddd is the static IP address assigned by your service provider for the PC, eee.fff.ggg.hhh is the
subnet mask assigned by your service provider to PC)
>
dhcpserver config confirm
↵
(confirm the new configuration)
>
config save
↵
(save the new configuration)
>
restart
↵
(after restart new configuration will take effect)
