Tp-Link TL-SG1016DE V2 [42/48] Qos basic

DSCP priority in the range of 0 to 63. The last 2 bits (bit 6 and bit 7) are reserved. The mapping

relationship between sixty-four DSCP priority value and priority queues is shown as follows:

 Priority 0 to 15 are assigned to the 1 (Lowest) priority queue.

 Priority 16 to 31 are assigned to the 2 (Normal) priority queue.

 Priority 32 to 47 are assigned to the 3 (Medium) priority queue.

 Priority 48 to 63 are assigned to the 4 (Highest) priority queue.

When DSCP QoS mode is enabled, the switch will automatically map the ingress packets to

priority queues based on the DSCP precedence and the above mapping relationship. After that,

packets in all the queues are sent in order based on the weight value for each queue. The switch

implements four scheduling queues, TC1, TC2, TC3 and TC4. TC1 has the lowest priority while

TC4 has the highest priority. The weight value ratio of TC1, TC2, TC3 and TC4 is 1:2:4:8. As for

the untagged packets, the switch will forward it according to the default priority mode.

The QoS module is mainly for priority configuration and traffic control, including three submenus:

QoS Basic, Bandwidth Control and Storm Control.

8.1 QoS Basic

This switch classifies the ingress packets, maps the packets to different priority queues and then

forwards the packets to implement QoS function.

This switch implements three priority modes based on port /802.1P /DSCP. The port-based QoS

mode supports four priority queues. The port priority queues are labeled as 1, 2, 3, and 4.

On this page you can configure and view QoS mode and the port-based priority setting.
