3. Use the mab command in Cable Service Class mode to specify the bandwidth
that a service class is permitted to consume on an interface.
The service class MAB is applied during admission control to determine whether
to admit a new service flow and again by the packet schedulers to provide a
class-based weighting to the scheduler
.
MOT(config-srvclass)#

is the service class name.
1-100
is the percent of the total interface bandwidth capacity.
Note: The default MAB for any user-defined service class is set to 1
regardless of the scheduling type.
Note: When configuring the Maximum Assigned Bandwidth (MAB) for service
classes, it is not permitted to configure MABs such that the sum of the MABs
for all service classes for each direction (upstream and downstream) exceeds
100 percent. Refer to
Calculating MAB Percentages .
Note: For scheduling purposes, each service class gets its bandwidth based
on its MAB fraction relative to other classes, not based on the absolute value
of the MAB. For example, if there are only two active service classes and
both have the same MAB, each service class would get 50% of the
bandwidth. The absolute value of the MAB is only used for admission control
not scheduling.
