[c-nsp] CPU utilization for handling interrupt

[Waseem]

Hi,
I'm seeing the following output for " show interface gig x/y switching"
ROUTER#sh inter gig x/y switching

The IP Process and IP Fast are accumulating .
The config. of the interface is as follows:
----------------------------------------------

interface GigabitEthernet x/y
 ip address x.x.x.x x.x.x.x
 ip verify unicast source reachable-via rx allow-default
 no ip redirects
 no ip proxy-arp
 ip tcp adjust-mss 1400
 speed nonegotiate
 no cdp enable
 service-policy input POLICY
 service-policy output POLICY
end
------------------------------------------------
