[c-nsp] FWSM traffic distribution across internal etherchannel

[NMaio at guesswho.com]

You have the same options that you normally do with all other etherchannels.  Use the following command to change the hashing algorithm.  

Keep in mind this affects all etherchannel in the chassis.

Router(config)# port-channel load-balance {dst-ip | dst-mac | dst-port | src-dst-ip | 
src-dst-mac | src-dst-port | src-ip | src-mac | src-port}

dst-ip—Load distribution on the destination IP address 
dst-mac—Load distribution on the destination MAC address 
src-dst-ip—Load distribution on the source XOR destination IP address 
src-dst-mac—Load distribution on the source XOR destination MAC address 
src-ip—Load distribution on the source IP address 
src-mac—Load distribution on the source MAC address 
src-port—Load distribution on the source port 
dst-port—Load distribution on the destination port 
src-dst-port—Load distribution on the source XOR destination port

Subject: [c-nsp] FWSM traffic distribution across internal etherchannel

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?
