[c-nsp] 7507 GEIP Controller

Well, the CPU usage is high even without cable. I started generating CPU
graph and it shows the CPU usage is pretty high after inserting GEIP
controller in. I tried to get "sh stack" picture and according to stats
"Network Interrupt" is being called higher than others. Traffic is being
passed from this interface and there are no CRCs or input errors.
The question is, how can I check the GEIP controller is faulty or GEIP card?
How can one check that faulty card is causing high cpu load while the card
is working good if we talk about traffic passing out/in from that interface.
Is there any workaround for such issues? What do you suggest upgarding from
12.4 (3a) to 12.4 (16) will have positive impact :)
Anyways once again thanks for your reply.
Regards,
Masood Ahmad Shah

For packet switching it shouldn't but if the driver is still sending an
interrupt it may.

Because it's interrupt level work the CPU is doing. We could try profiling
the CPU and see what it says.
It may or may not help.

Get a couple of sh stacks and look at the interrupt level calls and see
which one is going up the most.
It may be a bad card.
