Full duplex would help if collisions were the problem. But over the last 26
hours, this interface has only transmitted 19,000 packets, with 38
collisions. 30 million broadcasts in 26 hours is about 320 per second on
average. That's a broadcast storm of some type. The router is doing SPD to
protect itself. Something on the other end of the wire is the cause.
