4.1.5 Notes on using shaper

(1) Notes on scheduling when packet buffers are exhausted

If traffic exceeding the bandwidth of the output line is received, the packet buffer on the Switch might be depleted. As a result, frames might not be sent according to the specified schedule because the received frames are discarded and are not queued in the queue.

To check for depletion, use the show qos queueing command to check whether the HOL1 counter has been incremented.

If the packet buffer is depleted frequently, you need to review the network design.
