TP-LINK JetStream TL-SG3216 TL-SG3216 Data Sheet

 

The following entries are displayed on this screen:

 

¾

Indicates the precedence level defined by IEEE802.1P and the 
CoS ID. 

Indicates the priority level of egress queue the packets with tag 
and CoS-id are mapped to. The priority levels of egress queue are 
labeled as TC0, TC1, TC2 and TC3. 

Configuration Procedure: 

1  Configure the mapping 

relation between the 802.1P 
priority Tag/CoS and the TC 

Required. On QoS→DiffServ→802.1P/CoS mapping 
page, configure the mapping relation between the 
802.1P priority Tag/CoS and the TC. 

2 

Select a schedule mode 

Required. On QoS→DiffServ→Schedule Mode page,, 
select a schedule mode. 

On this page you can select a schedule mode for the switch. When the network is congested, the 
problem that many packets compete for resources must be solved, usually in the way of queue 
scheduling. The switch will control the forwarding sequence of the packets according to the priority 
queues and scheduling algorithms you set. On this switch, the priority levels are labeled as TC0, 
TC1… TC3. 

Choose the menu QoS→DiffServ→Schedule Mode to load the following page. 

 

Figure 9-9 Schedule Mode 

The following entries are displayed on this screen:

 

¾

Strict-Priority Mode. In this mode, the queue with higher priority will 
occupy the whole bandwidth. Packets in the queue with lower 
priority are sent only when the queue with higher priority is empty.   

Weight Round Robin Mode. In this mode, packets in all the queues 
are sent in order based on the weight value for each queue. The 
weight value ratio of TC0, TC1, TC2 and TC3 is 1:2:4:8.
