For this example, switch port 1 has been designated by the system administrator as the preferred network
management traffic port:
qos traffic-profile set port 1 name mgmtTraf
After filter set installation, switch resource usage reflects the resources consumed by "mgmtTraf" (7
precedence levels/masks and 7 filters/counters):

Suppose the administrator decides that port 1 is to be used exclusively for network management traffic.
All non-management traffic should be dropped. This is easily accomplished by adding a catch-all filter at
the end of the filter set to match and drop all non-network management traffic. Note that the evaluation
order dictates where in the filter set the new classifier element will be placed (i.e., last to be evaluated).
All filter set classifier elements with an evaluation order lower than the "drop-all" filter need to ensure that
the identified network management traffic is 'passed' (action: drop disable) so that the new classifier
doesn't accidentally impact the wrong flows:
qos traffic-profile classifier name mgmtTraf drop-action enable eval-order 100
