For example, suppose that you want to prioritize inbound traffic on the
following source-ports:
Interface Priority
(Source Port)
1 - 3 2
4 3
5, 8 5
9 - 11 6
You would then execute the following commands to prioritize traffic received
on the above ports:
Figure 6-27. Configuring and Displaying Source-Port QoS Priorities
If you then decided to remove port 1 from QoS prioritization:
Figure 6-28. Returning a QoS-Prioritized VLAN to "No-override" Status
Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Types To Configure QoS for Outbound Traffic
In this instance, No-
override indicates that port
A1 is not prioritized by QoS.
