[c-nsp] FWSM traffic distribution across internal etherchannel

[NMaio at guesswho.com]

David,
The section named "Customizing the FWSM Internal Interface" in the following page
http://www.cisco.com/en/US/docs/security/fwsm/fwsm31/configuration/guide/switch_f.html
would be helpful.

As you stated you would need to know the traffic profile to detemine the correct algorithm but why would you say that there aren't any commands to change this?  The command is not run in the fwsm but rather the switch/router.
Nick

Hi Jack,

Yes, it is most likely that this is normal.  There are no CLI commands
on the FWSM to adjust this. I would have to understand your traffic
profile along with your config to tell you why the given profile is
almost exclusively utilizing ports 3 and 6.

Sincerely,

David.
