I have noticed on the configurator. for the WS-X6748-ge-tx module. Under the distributed forwarding card options they have none selected or ws-f6700-cfc or the ws-f6700-dfc3a. I understand the difference in the dfc card and no daugther card, but what is the cfc card, and what does features does it add. Also I notice there is no charge for the cfc card.
The cfc (centralized forwarding card) enables the ws-x6748-ge-tx to work in cef256 mode. This mode means that switching decisions are made centrally on the sup720. The dfc3a allows the ws-x6748-ge-tx work in dCEF720 mode and can make the switching decision on the dfc3a instead of asking the main supervisor to make the switching decision.
All ws-x6748-ge-tx come with either the cfc or dfc3a. I'm suprised you can order it without it.
I went to the ordering tool and tried to order a ws-x6748-ge-tx and was given the option to choose a dfc3a. If i chose nothing, it automatically included a cfc.
Thankyou for the clarification. But now I have another question. Can I mix cards that have cef256 and cdef256, and still do the distributed for the cards that have the functionality or does it step down to the lowest common demoninator (cef). My situation is that I have sup720s +48 port 10/100/1000 cards with dcef daughter cards and 16 port gbic cards that have cef daughter cards.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
