maximum bandwidth configuration. It is effectively a second-level shaping
mechanism. The default value is 0. The value 0 means that the maximum is unlimited.
The expected shaping at egress interface is calculated as follows:
•
frameSize × shaping/(frameSize + IFG), where IFG (Inter frame gap) is 20 bytes,
•
frameSize is configured frame size, and shaping is configured traffic shaping.
For example, if 64 bytes frame size and 64 kbps shaping are configured, the expected
shaping is approximately 48 kbps.

Configure CoS queue settings for an interface
You can define what a particular queue does by configuring switch egress queues. You
can control how much bandwidth is used by the queue, the queue depth during times
of congestion, and the scheduling of packet transmission from all queues on a port.
Each port contains its own CoS queue-related configuration.
For information about configuring CoS queue settings globally, see Configure the CoS
trust mode settings globally or for a specific interface on page 455.
