Changing the default queuing policy may be preferred and enables flexible application of
QoS policies.
Note
Changes to the queuing policy are disruptive to traffic transiting the ports being
modified.
The default queuing policies cannot be modified directly. There are two options to make
changes to the default queuing policies. The first option is to copy the default policy to a
new policy and then modify the new policy. This makes it possible to revert back to the
defaults in the event the changes made need to be reversed. Example 10-12 describes how
to copy a default policy to a new policy for editing.
