English, as it has been for a couple of years now ;)

DHCP is irrelevant to NAV.  NAV only cares about the bridge tables of
the switches, and these are collected every 15 minutes.  The camlogger
can be configured to watch the bridge tables for specific MAC addresses
and issue a warning in its log file when they appear (no one has really
used this feature much, and we were led to believe it would actually
send an e-mail warning).

So you have two choices, really: You can add a list of MAC adresses to
/etc/nav/watchMacs.conf and create a process that monitors
getBoksMacs.log and dispatches e-mail/sms when MAC warnings occur.  Or,
you can do the same with a process that monitors your DHCP logs (if
possible).  The latter will give you more immediate warnings than using
NAV's method.
