Quality of Service (QoS): Managing Bandwidth More Effectively
Introduction
You can configure a QoS priority of 0 through 3 for an outbound packet. When the packet is then sent to a port, the QoS priority determines which outbound queue the packet uses:
TableQoS Priority Setting | Outbound Port Queue |

|
medium priority (5,6) | |
