Help to understand show buffers output

[rsrodrigo]

Hello.

I need some help to understand the output of show buffers command. At Big buffers and VeryBig buffers appear informations in "misses", "trims" and "created" like:

Big buffers:

14368763 hits, 631 misses, 348 trims, 348 created

66 failures (0 no memory)

VeryBig buffers:

592457 hits, 35 misses, 35 trims, 35 created

0 failures (0 no memory)

My router is a Cisco 1005. Does anyone help me to understand whether this informations above are troubles or not? I need to certificate the performance of the router...

Thanks for all.

Hits identifies the number of buffers that have been requested from the pool. The hits counter provides a mechanism to determine which pool must meet the highest demand for buffers.

Misses identifies the number of times that a buffer has been requested and the RP detected in which pool additional buffers were required. In other words, the number of buffers in the free list has dropped below min level. The misses counter represents the number of times the RP has been forced to create additional buffers.

Trims identifies the number of buffers that the RP has trimmed from the pool, when the number of buffers in the free list exceeded the number of max-allowed buffers
