A user group consists of a group of local users and has a set of local user attributes. You can configure
local user attributes for a user group to implement centralized management of user attributes for the
local users in the group. Currently, you can configure authorization attributes for a user group.
Note that:
A user group with one or more local users cannot be removed.
The default system user group system cannot be removed but you can change its configurations.
Related commands: display user-group.
