To avoid IP address conflicts, the DHCP server checks whether an IP address is in use before assigning it
to a DHCP client.
The DHCP server pings the IP address to be assigned by using ICMP. If the server gets a response within
the specified period, the server selects and pings another IP address. If not, the server pings the IP
addresses once again until the specified number of ping packets are sent. If still no response is received,
the server assigns the IP address to the requesting client.
Examples
# Specify the response timeout time as 1000 ms.

[Sysname] dhcp server ping timeout 1000
