What does the shaping metric mean?
Example: A 7500 can be keyed at 0Mbps, 10Mbps, 45Mbps, 100Mbps or 200Mbps. If you just want the monitoring abilities, then get a 7500-L000M – also known as a Packetseeker, because it doesn’t shape any traffic. If you have a 10Mpbs link or less – like a couple of T1s, then get a 45M key. If you have a DS3, then get a 45Mbps key, and so on. The amound of bandwidth out to the internet is the amount you need to be able to shape with the Packetshaper.
