[c-nsp] FWSM traffic distribution across internal etherchannel

[jack b]

I have a FWSM running 2.3(4)11 in slot 4 of a 6509. I have noticed that I am
getting unequal traffic distribution on the links that make up the ether
channel bundle  between the FWSM and 6509.

Here is a snapshot of the traffic distribution

4/1    in 28.99mbps    out 458.10mbps
4/2    in 12.37mbps    out 248.31mbps
4/3    in 960.86mbps  out 294.95mbps
4/4    in 34.07mbps    out 505.22mbps
4/5    in 15.08mbps    out 243.10mbps
4/6    in 950.63mbps  out 262.68mbps

In is traffic from the FWSM to the switch and out is traffic from the switch
to the FWSM.

Is this normal operation, or is there a way to distribute the traffic from
the FWSM to the switch more evenly?
