I'm not sure if you mean in your /etc/network/interfaces script or from 
the shell.  Assuming I'm working with eth1:

When I'm debugging dhcp issues from the shell, I run:

dhclient -v eth1

The verbose output is useful in place of a packet sniffer to see info on 
the handshake

In my interfaces script:

auto eth1
iface eth1 inet dhcp

Of course, you'll need to have the right packages installed.  I think 
you want dhcp-client and init-ifupdown
