A class is a group of users, defined by IP address. All users within the group receive the same quality of bandwidth service, as defined by the shaping policy.
The Bandwidth Management module comes with an All traffic class pre-defined. This is a “catch-all” class for traffic originating from an IP address not assigned to a existing class. The Default shaping policy is applied. For more information about shaping policies, see Creating Bandwidth Management Shaping Policies.
