You can configure and attach as many output policy maps as there are switch ports, but only three unique queue-limit
configurations are allowed. When another output policy map uses the same queue-limit and class configurations, even
if the bandwidth percentages are different, it is considered to be the same queue-limit configuration.
Configuring QoS
Before configuring QoS, you must have a thorough understanding of these factors:
 The types of applications used and the traffic patterns on your network.
 Traffic characteristics and needs of your network. Is the traffic bursty? Do you need to reserve bandwidth for voice
and video streams?
 Bandwidth requirements and speed of the network.
 Location of congestion points in the network.
These sections describe how to classify, police, and mark incoming traffic, and schedule and queue outgoing traffic.
Depending on your network configuration, you must perform one or more of these tasks.

Default QoS Configuration
There are no policy maps, class maps, table maps, or policers configured. At the egress port, all traffic goes through a
single default queue that is given the full operational port bandwidth. The default size of the default queue is 160
(256-byte) packets.
