You can probably set (IIRC) option lease-time in the client config to
set what it asks for.
However, just to correct your thinking, the client has very little
say in how long the lease is. It can REQUEST any length it likes, but
it MUST either accept and work to the lease time offered by the
server OR not accept the lease. What it absolutely cannot do is work
to any different lease length.
The only exception would be that a client is obviously free to just
stop using an address it's leased - but unless it explicitly sends a
DHCPRELEASE message to the server then the server cannot give that
address out to another client until it expires according to the
To summarise: the client can request a specific lease length, the
server will decide what lease length is actually offered.
