What Is the Buffer of an Interface on a CE Switch?

What Is the Buffer of an Interface on a CE Switch?

Buffer threshold parameters of an interface include the reserved buffer threshold, threshold for triggering flow control, threshold for stopping flow control, and headroom buffer size.

For CloudEngine switches running V200R003C00 and later versions, you can run the flow-control [ input | output ] buffer { reserved reserved-value | xon xon-value | xoff xoff-value | hdrm hdrm-value } command in the interface view to modify values of the buffer threshold parameters of an interface.

The following tables list default values and value ranges of different buffer threshold parameters on interfaces of different models of devices.
