I have a network of about 4600 devices. One item that takes up alot of my time is "deleting" routers and switches in Cisco Works 3.2 when a device has been removed (like for office closure or new device was installed, but not with same IP address as the old device it is replacing). Would like to know if there is a way to "delete" a device when discovery has not seen it for say 30 days.
