ip dhcp ping packets

Server sends to a pool address as part of a ping operation, use the ip dhcp ping packets global
configuration command. Use the no form of this command to prevent the server from pinging pool
addresses.

Usage Guidelines
This command first appeared in Cisco IOS Release 12.0(1)T.
The DHCP server pings a pool address before assigning the address to a requesting client. If the ping
is unanswered, the DHCP server assumes (with a high probability) that the address is not in use and
assigns the address to the requesting client.
Examples
The following example specifies five ping attempts by the DHCP server before ceasing any further
ping attempts:
ip dhcp ping packets 5
