timeframe and then collecting the counter details at the end of the period. Those counters are usually available via SNMP, but clearing them may have to be done manually. Or you could collect the start value and do some maths. It really depends on how complex
you want to make it and what tools you have available.<o:p></o:p></span></p>

<p class="MsoNormal">Hi All,<br>
<br>
I would like a tool that could tell me exactly how many switch ports are in use across a given time period.<br>
This is an enterprise environment so it’s not just the case of taking a snapshot in time, devices turn on and off so I’d want something that could monitor the port counts for a week or so and spit out a report.<br>
<br>
Also, as per usual, the cheaper (free?) the better!<br>
<br>
Any ideas?<br>
<br>
