DiffServ, ¾ Port Priority Config | TP-Link TL-SG2008 specification

The QoS module is mainly for traffic control and priority configuration, including two submenus: DiffServ and Bandwidth Control.

9.1 DiffServ

This switch classifies the ingress packets, maps the packets to different priority queues and then forwards the packets according to specified scheduling algorithms to implement QoS function.

This switch implements three priority modes based on port, on 802.1P and on DSCP, and supports four queue scheduling algorithms. The port priorities are labeled as TC0, TC1, TC2 and TC3.

The DiffServ function can be implemented on Port Priority, 802.1P Priority, DSCP Priority and Schedule Mode pages.

9.1.1 Port Priority

On this page you can configure the port priority.

Choose the menu QoS→DiffServ→Port Priority to load the following page.

Figure 9-6 Port Priority Config

The following entries are displayed on this screen:
