fragmentation statistics

[slavon]

some extract from cisco guide:

"Verifying Pre-Fragmentation For IPSec VPNs

To verify that this feature is enabled, consult the interface statistics on the encrypting router and the decrypting router. If fragmentation occurs on the encrypting router, and no reassembly occurs on the decrypting router, fragmentation is happening before encryption, and thus the packets are not being reassembled before decryption. This means that the feature is enabled."

Does anyone know how to view fragmentation statistics on interface?

I think the command that you are looking for is "show ip traffic". The first section of the output, 'IP Statistics' has a sub-section called 'Frags' that should give you all the stats that you are looking for.

Thanks for the answer. Is there a way to clear this statistics? I did not find anything that could do it.
