R3303-HP HSR6800 Routers Layer 3 - IP Services Command Reference

31
Parameters
number: Specifies the maximum number of ping packets, in the range of 0 to 10. The value of 0 means
that the DHCP server does not perform address conflict detection.
Usage guidelines
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. If the server gets a response within the specified period, the server
believes that the IP address is in use, selects and pings another IP address. If not, the server pings the IP
address again until the maximum number of ping packets are sent. If still no response is received, the
server assigns the IP address to the requesting client.

# Specify the maximum number of ping packets as 10.
