A 6509 should not "fall over without DFC's" unless you are doing more than 30mpps. That is 15gbit/s of 64 byte packets or 360gbit/s of 1500 byte packets.
It should 'fall over' even if the traffic will rise, and there won't be enough PFC Mpps to do the work - simply switch fabric channels will fill up with traffic going to the PFC. Adding DFCs will increase the performance in terms of pps in that situation - people do this all the time when their configs top the performance envelope of the current setup. -- "Everything will be okay in the end. | Łukasz Bromirski If it's not okay, it's not the end. | http://lukasz.bromirski.net _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
