Quality of Service (QoS) Objects

This section describes the parameters and configuration commands that define QoS.
QoS control enables transmission of IP packets by priority, with highest-priority
packets transmitted first. The following is a brief description of each component of
the overall QoS control mechanism, with associated configuration commands
displayed for each block.
1. QoS enable/disable
QoS information (qos) specifies whether QoS is functional or nonfunctional.
Flow Control (input)
Priority Determination
TOS Rewrite
Contracted Bandwidth
Monitoring
: Control range of this command

Figure 1-4 Control Range of QoS Information

2. Transmission control
Transmission control determines the output queue mode, thereby controlling the
precedence of packets on the interface output queue. There are three queue
modes: priority, round-robin, and bandwidth. The QoS queue attribute command
(qos-queue-list) generates interface output queue lists; the QoS interface
command (qos-interface) applies the queue list for each interface.
Flow Control (input)
Priority Determination
TOS Rewrite
Contracted Bandwidth
Monitoring
: Control range of this command
