	If you just want to investigate using RMON to capture packets I
believe that NTOP now has an RMON plugin.  On the other hand if you are
trying to investigate the impact of turning on RMON on switches that's a
different matter.  We regularly run the RMON agent on our Cisco Cat 5500 and
I've not heard anyone complain.

Subject: [ethereal-dev] Using RMON on switches to capture packets


Hi,

I would like to start investigating the subject of using RMON on (some)
switches to capture packets.

I am told that some switches have some level of RMON and that it might be
possible to capture packets from them.

I am also told that if one does that they will probably drop back to using
the processor to switch rather than the backplane and that performance
might suffer.

My problems are:

  - Finding a switch that includes the right stuff
  - getting my hands on such a switch.



Regards
