Ours dropped about 70% ... And it's been steady ever since.. we've added a large number of modems since that time as well... Look into 'no cable-arp' as well ... Basically, it prevents arp broadcasts and that also had a major impact on the cpu utilization of our CMTS's.. Jason Frisvold Backbone Engineering Supervisor Penteledata

hello!
The G1 processors, so far, have proven to be wonderful... We only have experience with them running in the 7200 uBR chassis, but they've shown a huge reduction in CPU utilization...
what is huge reduction for you? we upgraded from npe-400 to npe-g1 on ubr7200 and processor usage decreased 20-30%. And we are pushing about 100Mbps traffic from GigE to cable and about 20-30Mbps from cable to GigE.
