Usage Guidelines

Usage Scenario

By default, the TM is enabled to buffer and schedule packets. When heavy traffic needs to be forwarded on all interfaces, the device cannot ensure lossless forwarding. You can run the undo qos traffic-manage enable command to disable the TM from buffering and scheduling packets.

Configuration Note

After the undo qos traffic-manage enable command is executed, the S5720-HI does not support queue-based traffic shaping, WRED, queue statistics collection, and congestion management.

After the undo qos traffic-manage enable command is executed, the switch does not support HQoS.

After the undo qos traffic-manage enable command is executed, the buffer of the device is greatly reduced.

Example
