Parameter
Description
Using the dhcp server ping command, you can configure the maximum number of
ping packets that the DHCP server is allowed to send and the longest time period
that the DHCP server should wait for the response to each ping packet. Using the
undo dhcp server ping command, you can restore the default settings.
To prevent the address collision resulted from repeated IP address allocation, DHCP
server sends ping packets to detect that an address is available.
Example
Allow the DHCP server to send up to ten ping packets and wait 500 milliseconds
(the default setting) for the response to each packet.
