hey all,

Quick question for you, hope you can help me.

Im working on installing the DFCs in existing 67xx cards in our 7600s:

7606 w/SUP720-3BXL
2 x 6748-GE-TX
1 x 6704

Im aware there are some differences in how the box reacts when a DFC is
installed (the PFC will no longer need to make all the decisions, etc...).
In particular this seems to change the beahviour for qos policers as well as
L2 etherchannels.  Im using both of these, but I cant seem to find any
definite documentation on CCO explaining the exact changes and perhaps any
recommendations.  Of course I need to know how the box will behave in order
to plan for this as part of the DFC upgrade, and so far all I found was an
FAQ at
http://www.cisco.com/en/US/products/hw/switches/ps708/products_qanda_item09186a00809a7673.shtmlwhich
doesn't give so much detail, and a few items in the archives of the
list which touched the surface but didnt dig deep.

would appreciate if anyone can share any detailed info as to how qos and
etherchannel behaviour changes in PFC vs DFCX3BXL

thanks,

anton
