qos dynamic-buffer enable
Function
The qos dynamic-buffer enable command enables dynamic queue buffer adjustment.
The undo qos dynamic-buffer enable command disables dynamic queue buffer adjustment.
By default, the device does not dynamically adjust the queue buffer.
This command is available only on the following switch models:
S5735-L, S5735S-L, S5735S-L-M, S5735-S, S5735-S-I, and S5735S-S
Usage Guidelines
Usage Scenario
If congestion occurs, the switch uses the tail drop method. When the queue length reaches the upper limit, excess packets (buffered at the queue tail) are discarded until congestion is removed. You can run the qos dynamic-buffer enable command to enable dynamic queue buffer adjustment. This ensures that a queue has sufficient buffer space, preventing packets from being discarded. To configure the interval for dynamically adjusting the queue buffer, run the qos dynamic-buffer interval command; to configure the maximum buffer size of a queue for which dynamic buffer adjustment is enabled, run the qos dynamic-buffer max-maximum command.
Precautions
This command takes effect only when multicast entries exist.
