The following entries are displayed on this screen:

Priority and CoS-mapping Config

Tag-id/Cos-id:Indicates the precedence level defined by IEEE802.1P and the

CoS ID.

Queue TC-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.

9.1.4 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:

Schedule Mode Config

SP-Mode: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.

WRR-Mode: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.
