3.1.3 Forwarding Classes
Queues can be created for each forwarding class to determine the manner in which
the queue output is scheduled and the type of parameters the queue accepts. The
7705 SAR supports eight forwarding classes per SAP. Table 2 shows the default
mapping of these forwarding classes in order of priority, with Network Control having
the highest priority.
