Even with fabric enable blades in the c6500, you are going to get massive
output buffer overflows. Market data has very uneven traffic patterns causing
microburst effects. What sup-engines/blades are on the boxes? What type of
multicast replication is being used (ingress/egress). QoS policies typically
make matters worse. What type of interfaces are on the 6500?
