Parameters

milliseconds: Specifies the timeout time in the range of 0 to 10000 milliseconds. To disable the ping

operation for address conflict detection, set the value to 0 milliseconds.

Usage guidelines

To avoid IP address conflicts, the DHCP server pings an IP address before assigning it to a DHCP client.

If a ping attempt succeeds, the server considers that the IP address is in use and picks a new IP address.

If all the ping attempts are failed, the server assigns the IP address to the requesting DHCP client.

Examples

# Specify the response timeout time as 1000 milliseconds.
