qos dynamic-buffer interval

Function

The qos dynamic-buffer interval command configures the interval for dynamically adjusting the queue buffer.

The undo qos dynamic-buffer interval command restores the default interval for dynamically adjusting the queue buffer.

By default, the device dynamically adjusts the queue buffer at an interval of 100 ms.

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

Format

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. You can run the qos dynamic-buffer interval command to configure the interval for dynamically adjusting the queue buffer. A shorter interval indicates that the device performs dynamic adjustment of the queue buffer more frequently.

Precautions

This command takes effect only after the qos dynamic-buffer enable command is run to enable dynamic queue buffer adjustment.

Example

# Set the interval for dynamically adjusting the queue buffer to 1000 ms.
