Configuring QoS Class of Service Configuration Scheduler Type Select the type of scheduling used for corresponding queue. When the network congestion occurs, the egress queue will determine the forwarding sequence of the packets according to the type. Strict: In this mode, the egress queue will use SP (Strict Priority) to process the traffic in different queues. When congestion occurs, the traffic will be transmitted according to its queue priority strictly. The queue with higher priority occupies the whole bandwidth. Packets in the queue with lower priority are sent only when the queue with higher priority is empty. Weighted: In this mode, the egress queue will use WRR (Weighted Round Robin) to process the traffic in different queues. When congestion occurs, all the traffic will be transmitted, but the bandwidth that each traffic queue occupies will be allocated based on the queue weight. Queue Weight Specify the queue weight for the desired queue. This value can be set only in the Weighted mode. The valid values are from 1 to 127. Management Type Displays the Management Type for the queues. The switch supports Taildrop mode. When the traffic exceeds the limit, the additional traffic will be dropped. 3) Click Apply. Note: With ACL Redirect feature, the switch maps all the packets that meet the configured ACL rules to the new TC queue, regardless of the mapping relations configured in this section. 2.2 Using CLI 2.2.1 Configuring Port Priority ■■ Configuring the Trust Mode and the port to 802.1p Mapping Follow these steps to configure the trust mode and the port to 802.1p mapping: Step 1 configure Enter global configuration mode Step 2 interface {fastEthernet port | range fastEthernet port-list | gigabitEthernet port | range gigabitEthernet port-list | ten-gigabitEthernet port | range ten-gigabitEthernet port-list | port-channel port-channel-id | range port-channel port-channel-list} Enter interface configuration mode.
