Suggestions? What platform is used? ASR9000? It has ~50 ms of FIFO buffering per port if nothing is configured if I remember correctly. policy-map EGRESS class class-default random-detect precedence 0 10 ms 30 ms int teng0/0/0/0 service-policy EGRESS output This should create a policy-map called EGRESS which does WRED for prec 0 traffic with 0% drop until 10 ms and 100% drop at 30ms of buffer depth, and then this is attached in the egress-direction on tengi0/0/0/0 > Very interesting data thus far.

I'm kind of disappointed that they don't have enough bw there, lately these kinds of events have had more bandwidth available than has been used because ISPs and vendors have used them as tech demonstrators, and also that people have enough bw available at home so it's been less downloading/uploading done there. -- Mikael Abrahamsson email: swmike@swm.pp.se
