Hi Stephen, <div><br></div><div>Just following up here but `limit (see below)` is the number of bytes not number of packets. Therefore it should be: </div><div><br></div><div>1gigbit/sec *.042seconds = 134,217,728(bytes/seconds) *.042seconds = 5,637,144.58 (Then round up). </div>
<div><br></div><div>Right? </div><div><br></div><div>Thanks, </div><div><br></div><div>Aaron</div><div><br></div><div><br><span style="font-weight:bold;color:#204a87"> </span>Limit is the number of bytes that can be queued waiting for tokens to become available. You can also specify this the other way around by setting the latency parameter, which specifies the maximum amount of time a packet can sit in the TBF. The latter calculation takes into account the size of the bucket, the rate and possibly the peakrate (if set). These two parameters are mutually exclusive.<div>

</div>Do you mean that there is a possibility to have a VLAN device with a queue?<br>
