The following command should help (I've added some
example output):

tinka at lab# run show chassis pic fpc-slot 2 pic-slot 1    
FPC slot 2, PIC slot 1 information:
  Type                             1x 10GE(LAN/WAN) IQ2
  State                            Online    
  PIC version                 1.11
  CPU load average               0 percent
  Interrupt load average         0 percent
  Total DRAM size              128 MB
  Memory buffer utilization     54 percent
  Memory heap utilization       10 percent
  Uptime			 177 days, 15 hours, 39 minutes, 5 seconds

PIC port information:
                          Fiber                    Xcvr vendor

As you can see, the command also provides you with
CPU and Interrupt load averages for the PIC.

Even though this particular interface is doing a
couple of Gbps of traffic, the card's CPU is
unphased. That's because the CPU on the PIC is not
used to forward traffic.

Hope this helps.

Cheers,

Mark.
