Hello,
Do you have any ideea on how to see what interrups are loading a router's
CPU?
It is (tediously) difficult to break down interrupt CPU use.
The best approach is to SPAN the RP or SP CPU ports:
http://cisco.cluepon.net/index.php/6500_SPAN_the_RP
...and see if you're getting a lot of packets.
You can try doing:
sh ip traffic
...and comparing snapshots a few seconds apart to see if you're getting
e.g. a lot of packets causing time-exceeded or ICMP unreachables.
