Configuring Congestion Management
Configuring Congestion Management
Pre-configuration Tasks
When a network is congested intermittently, configure congestion management on the device. The device then determines the sequence at which packets are forwarded according to the defined scheduling policy and ensures that high-priority services are scheduled preferentially.
Before configuring congestion management, map the priority of packets to a PHB.
Context
Each interface can be configured with a maximum of eight queues. Different queues can use different scheduling modes. The device schedules the PQ queue first. If multiple PQ queues exist, the device schedules the queues in descending order of priority. A larger queue index indicates higher priority of a queue. After all the PQ queues are scheduled, the device schedules the WRR or DRR or WFQ queues in turn.
For CE12800, congestion management applies only to unicast traffic.
