The switch's ARP cache will only contain entries for addresses that
are communicating directly with the switch on layer 3 (i.e. your
workstation telnetting to the switch CLI).
This information is mostly useless - NAV will only collect ARP caches
from routers, which provides us with every active, routed IP address
in your network (assuming you're using NAV to monitor all the routers
in your network).

P.S. I'm assuming you accidentally forgot to reply-to-all, so I'm
Cc'ing the nav-users list.
