In the policy the default class default-class cannot be associated with the traffic
behavior queue ef belongs to.
The sum of the bandwidth specified for the classes in the same policy to assured
forwarding (queue af) and expedited forwarding (queue ef) must be less than or
equal to the available bandwidth of the interface where the policy is applied.
The sum of percentages of the bandwidth specified for the classes in the same
policy to assured forwarding (queue af) and expedited forwarding (queue ef)
must be less than or equal to 100.
The bandwidth configuration for the classes in the same policy to assured
forwarding (queue af) and expedited forwarding (queue ef) must adopt the
value of the same type. For example, they all adopt the absolute value form or the
percentage form.
For the percentage form queue ef bandwidth pct percentage [ cbs-ratio ratio ],
CBS = Interface available bandwidth*percentage*ratio/100/1000
For the absolute value form queue ef bandwidth bandwidth [ cbs burst ], CBS =
burst, or = bandwidth*25 if burst is not specified.

# Configure packets to enter priority queue. The maximum bandwidth is 200 kbps
and CBS is 5000 bytes.
