Chapter 4 Service Configuration
When data packet enters the port, the switch will do the QoS initial mark which mainly
includes the initialization of TC QoS.
In the direction of switch egress, QoS is used to put the packet into the suitable queue
according to marked TC and do the corresponding queue scheduling algorithm and
congestion control algorithm according to the current queue configuration and modify it
according to 802.1p User priority or IP Dscp field of data packet.
Configuring QoS
The QoS configurations on ZXR10 2900E includes global-based QoS configuration and
port-based QoS configuration. Part of QoS configuration is related to ACL. The QoS
configuration includes the following commands:
