RTP PQ Configuration
Example
Network requirement
Configure RTP queuing on the interface and set the maximum reserved bandwidth
allocated for RTP priority queue to 70% of the available bandwidth.
Configure RTP priority queuing on the serial port Serial1/0. The starting port
number is 16384. The ending port number is 32767. The RTP packets use 64 kbps
bandwidth. If network convergence happens, the packets will enter RTP priority
queue.

Token Function of QoS
Configuring QoS Token When FTP is used to transfer data, the upper layer protocol such as TCP provides
the flow control function. This can however cause the configuration of CQ and
WFQ, if they are configured, to lose effect. This function provides a flow control
