[f-nsp] Determining the load on the ip-forwarding engine on a Bigiron

[Gunther Stammwitz]

Hello colleagues,
 
we're using several foundry Bigirons - some Ironcore and some Jetcore - and
I'd like to find out how much load there is on the ip-forwarding-engine.
On most Cisco routers one can check the cpu load of the Linecard but on a
foundry forwarding is done in hardware. Is there any way to find out how
much room there is left and how high the utilization is?
 
As far as I understand a forwarding engine can usually forward x mpps with a
specific packet size which equals y megabits per second but much less
megabits if the packet size is smaller.
 
Any ideas?

I've seen show proc cpu and one can read "IP               0.19      0.13
0.13      0.15        4518345" there but I guess this means how much cpu of
the management card is being used by icmp-replies addressed to the router
itself?!?

Thanks,
Gunther
