Configuring Global QoS Parameters

This section describes the global QoS configuration, which includes enabling and disabling QoS, apply-
ing and activating the configuration, controlling the QoS log display, and configuring QoS port and queue
parameters.

Enabling/Disabling QoS

By default QoS is enabled on the switch. If QoS policies are configured and applied, the switch attempts
to classify traffic and apply relevant policy actions.
To disable the QoS, use the
-> qos disable
QoS is immediately disabled. When QoS is disabled globally, any flows coming into the switch are not
classified (matched to policies).
To re-enable QoS, enter the qos command with the enable option:
-> qos enable
QoS is immediately re-enabled. Any policies that are active on the switch are used to classify traffic
coming into the switch.
Note that individual policy rules can be enabled or disabled with the

Using the QoS Log

The QoS software in the switch creates its own log for QoS-specific events. You can modify the number
of lines in the log or change the level of detail given in the log. The PolicyView application, which is used
to create QoS policies stored on an LDAP server, query the switch for log events; or log events can be
immediately available to the PolicyView application through a CLI command. Log events can also be
forwarded to the console in real time.
What Kind of Information Is Logged
The debug qos command controls what kind of information is displayed in the log. The
command determines how specific the log messages are. See
By default, only the most basic QoS information is logged. The types of information that can be logged
includes rules, Layer 2 and Layer 3 information, etc. For a detailed explanation about the types of infor-
mation that can be logged, see the
