Tp-Link T3700G-28TQ V1 [279/415] 802 p priority

267

SP+WRR-Mode: Strict-

Priority + Weight Round Robin Mode. In this mode, this

switch provides two scheduling groups, SP group and WRR

group. Queues in SP group and WRR group are

scheduled strictly

based on strict-

priority mode while the queues inside WRR group

follow the WRR mode. In SP+WRR mode, TC7 is in the SP group;

TC0, TC1, TC2 to TC6 belong to the WRR group and the weight

value ratio of TC0, TC1, TC2 to TC6 is 1:2:4:8:16:32

:64. In this

way, when scheduling queues, the switch allows TC7 to occupy

the whole bandwidth following the SP mode and the TC0, TC1,

TC2 to TC6 in the WRR group will take up the bandwidth

according to their ratio 1:2:4:8:16:32:64.

Equ-Mode: Equal-Mode. I

n this mode, all the queues occupy the bandwidth

equally. The weight value ratio of all the queues is 1:1:1:1:1:1:1:1.

12.1.3 802.1P Priority

On this page you can configure the mapping relation between the 802.1P priority tag-id/CoS-id and

the TC-id.

802.1P gives the Pri field in 802.1Q tag a recommended definition. This field, ranging from 0-7, is

used to divide packets into 8 priorities. 802.1P Priority is enabled by default, so the packets with

802.1Q tag are mapped to different priority levels based on 802.1P priority mode but the untagged

packets are mapped based on port priority mode. With the same value, the 802.1P priority tag and

the CoS will be mapped to the same TC.
