Include the attempts statement to specify how many times the local server sends the
forcerenew or reconfigure message to initiate client reconfiguration. Include the
statement to set the interval between the first and second attempts. The interval between
each subsequent attempt doubles the previous value. For example, if the first value is 2,
the first retry is attempted 2 seconds after the first attempt fails. The second retry is
attempted 4 seconds after the first retry fails. The third retry is attempted 8 seconds
after the second retry fails, and so on.
By default, the DHCP client's original configuration is restored if all of the reconfiguration
attempts fail. Include the
