Groups
It is a good idea to sort your network devices (i.e.,
servers, routers, switches, etc.) into some kind of hierarchical group (e.g. by
location, by department, by importance, by project) to make the list of devices
easier to administer. So a "group" is a collection of several "servers".
For more information about editing groups and adding
servers to a group, see the Managing Groups section
of the manual.
