Hi,
I like to enable the above feature for 6500 core switches.
Core Switch I am using SUP720, as per the details from cisco
Line card is supporting DFC & SUP card is supporting PFC, so this feature will help us to redice unicast flodding across LAN
But how to check my Line card is supporting DFC
Command/docuemnt/guideline pls share

There are a couple of "show platform" commands depending on your software version.
See the document here.

Please run:
show platform hardware pfc mode
08-30-2013 07:17 AM
Hi,
show platform hardware pfc mode
PFC operating mode : PFC3B show platform hardware pfc mode
PFC operating mode : PFC3B
As per my knowledge, that is for SUP720 which is supporting PFC3B
But my concern is whether the Line card is DFC supported, so that I can go ahead to implement the same

Hi,
we have this following line cards
WS-X6748-SFP | WS-X6148-RJ-45 | WS-X6148-GE-TX | WS-X6148A-GE-TX | WS-X6408A-GBIC |
Pls share whether all is having DFC3 Support or not as till now I found 3,4 having DFC3 from this link
Pls share the docuemnt link
08-30-2013 07:48 AM
My understanding is that the 6148 and 6408 line cards are "classic" type line cards and thus not able to be upgraded with DFC3 module.
The 6748 is CEF720 type and may have DFC3.
08-30-2013 07:51 AM
Hi,
Just found that in another cisco link that 6748 also supporting DFC3
In that case( as 2 other card as mentioned by you are classic line card), can we enable above command of "mac sync"
Will it work

Hi
Pls respond

It should work but only to synchronize the Supervisor PFC3 with the 6748 - and only if it has the DFC3 installed.
Unless you are seeing specific operational issues with the lack of this feature being enabled would think it more trouble than benefit.
