cat2950 and buffer failure

I'm getting following stats for 'sh buffers' but there are absolutely no errors across the interfaces . I was expecting to see some errors. Is this correct ?

Re: cat2950 and buffer failure

A buffer miss simply means that the IOS had to spawn a process to increase the buffer pool, it is not an error. You do not have any failures through lack of memory so you may want to increase the permenant buffer allocations to reduce the number of misses.
