Someone has already discussed how you can use a 2500 as an RMON probe. But did you
know you can use a 2500 as a packet capture
device? The full RMON 1 capabilities of the 2500 include packet capture. You can
then download the captured packets for full
decode. This works great with a spare 2514 (two ethernet interfaces). Poor man's
network analyzer.
Quite impressive.
Take care,
