Hello Connie,
Thanks for posting the results, although I havenet tested this, I was
thinking because the manual bindings are stored in the nvram on the dhcp
server and the automatic bindings are stored as a database agent on remote
host. Because they are stored in 2 different locations, I thought that you
would need to put the excluded address.
Sincerely,
Matijevic
