No-buffer drops?

[ohauert]

I have implemented DiffServ ( LLQ queuing) on a serial interface. When congestion occurs, the statistics "no-buffer drops" appears. What is the meaning? (buffers seems not to be faulty).

Thanks

The no buffer counter increments when the interface fails to obtain a buffer for an incoming packet. More information can be found at this URL http://www.cisco.com/warp/public/650/41.html
