As far as I understand... (standard disclaimer)
The first number is the total CPU utilization...
The second number (after the /) is the total utilization that is being used
for interrupts. The difference between these 2 numbers is the amount the
router uses for the processes listed below the line. In your case almost
100% of the CPU usage is for interrupts (fast switching is something that
causes interrupts) and very little is being used for the various router
(proccess switching is done via a proccess) processes.
This is possibly good in the fact that all your traffic is being fast
switched but bad in the fact that the router is getting overloaded on
traffic at it's interfaces. The problem could be cuased by other things too
but without more info it's hard to say....

Subject: Can someone interpret this please?
Dear group,
Investigating a router that is starting to loaded down. When I do a sh proc
cpu I get 50% or cpu utilization but the stats don't seem to add up to 50%.
Is there another way to try and see where the 50% is coming from?
sh proc cpu
CPU utilization for five seconds: 44%/44%; one minute: 50%; five minutes:
52%
