fair-queue (class-default)
Table 4 lists the default number of dynamic queues used when CBWFQ is enabled on an ATM PVC.
Examples The following example configures policy for the default class included in the policy map called policy9.
Packets that do not satisfy match criteria specified for other classes whose policies are configured in the
same service policy are directed to the default class, for which 16 dynamic queues have been reserved.
Because the queue-limit command is configured, tail drop is used for each dynamic queue when the
maximum number of packets are enqueued and additional packets arrive.

The following example configures policy for the default class included in the policy map called policy8.

avoidance, Weighted Random Early Detection (WRED) packet drop is used, not tail drop.
