[c-nsp] Router 7200 + GE-PE module

[Werner Detter]

Hi,

as I've experienced the same, here's a short comment.

One of our 7206VXR crashed probably due to overloading a PA-GE-Card?
traffic on the Interface was around 270 Mbit/s IN and 38 Mbit/s out:

5 minute input rate 291395000 bits/sec, 29009 packets/sec
5 minute output rate 39685000 bits/sec, 23303 packets/sec

Shortly after that the router crashed and I've found something in the Crashdump:
"received master abort on primary bus"

PA-GE is definitly not able to handle 1 Gbit/s :)

Bye,
Werner
