The best debugging tool to find the right environment variables is;

    export > /tmp/dhclient.variables.txt

This shows you all the stuff you have to choose from.

What you're looking for probably is '${NEW_DHCP_SERVER_IDENTIFIER}".

NEW_ and OLD_ are prefixed to new and old configuration state, so that
the contents can be compared, and the config is only updated only when
it changes.
