Deciding to tune buffers
Dell Force10 recommends exercising caution when configuring any non-default buffer settings, as tuning
can significantly affect system performance. The default values work for most cases.
As a guideline, consider tuning buffers if traffic is very bursty (and coming from several interfaces). In this
case:
• Reduce the dedicated buffer on all queues/interfaces.
• Increase the dynamic buffer on all interfaces.
• Increase the cell pointers on a queue that you are expecting will receive the largest number of packets.
