Configuring Queuing; Configuring The Fifo Queue Size - HP A6600 Configuration Manual

The system matches packets with classification rules in the following order:
 Match packets with priority classes and then the other classes
Match packets with priority classes in the configuration order

RTP priority queuing
RTP priority queuing is a simple queuing technology designed to guarantee QoS for real-time services
(including voice and video services). It assigns RTP voice or video packets to high-priority queues for
preferential sending, minimizing delay and jitter, and ensuring QoS for voice or video services sensitive to
delay.

As shown in Figure
a UDP packet with an even destination port number in a configurable range. RTP priority queuing can be
used in conjunction with any queuing (such as, FIFO, PQ, CQ, WFQ, and CBQ), and it always has the
highest priority. Do not use RTP priority queuing in conjunction with CBQ. LLQ of CBQ can also guarantee
real-time service data transmission.

Configuring queuing

Configuring the FIFO queue size

FIFO is the default queue scheduling mechanism for an interface or PVC, and the FIFO queue size is
configurable.
The FIFO configuration is not available on a SAP interface card working in bridge mode.
You must enable the line rate function for the queuing function to take effect on these interfaces: tunnel
interfaces, subinterfaces, Layer 3 aggregate interfaces, HDLC link bundle interfaces, RPR logical interfaces,
and VT interfaces configured with PPPoE, PPPoA, or PPPoEoA encapsulation.
