Summary

Number of missing buffer elements is over threshold.

The number of missed buffers is above the maximum threshold configured in Xian Network Manager 2012.

Buffer missing occurs because of unavailable free buffer elements, inadequate memory, the lack of available free memory or incorrectly configured switches, with the consequent failure to perform internal operating system queues.

Resolutions

If your switch reports frequent buffer missing, you might want to perform buffer tuning to improve performance or increase the amount of memory in the switch.
