[nsp] Suggestions on tracking down bandwidth offenders

[Noriega, Alejandro]

You can start to know what kind of traffic is saturating your link.

Interface X
 ip nbar protocol-discovery
 load-interval 60
!
show ip nbar protocol-discovery Stats Byte-R | e 00

Be careful about cpu usage.

I've got a bandwidth problem (who doesn't).  Something has been 
saturating my poor little T1 for 24 hours straight now.  For those of 
you curious, here's what it looks like:

Remove the white space and enjoy.  In the past I've used ethereal dumps 
to figure out who the big talkers were, but frankly it takes too long to

crunch all the packets.  I've also tried etherApe, but the analysis 
makes my poor little laptop crawl.  Are there any tools out there that 
will speed this up?  Possibly by looking at the firewall logs?

Thanks
Tony
