Chapter 39 Configuring QoS

Understanding QoS

Queueing and Scheduling on Egress Queues

Figure 39-11 and Figure 39-12 show the queueing and scheduling flowcharts for egress ports.

Note If the expedite queue is enabled, SRR services it until it is empty before servicing the other three queues.

Receive packet from

the stack ring.

Read QoS label

(DSCP or CoS value).

Determine egress queue

number and threshold

based on the label.

Are thresholds

being exceeded?

Send the packet

out the port.

Queue the packet. Service

the queue according to

the SRR weights.

Drop packet.

Start

Done

Ye s

Rewrite DSCP and/or

CoS value as

appropriate.
