PFC-3B vs PFC-3BXL

I have a couples of 7609 equipped with Sup720-3B, and I'm going to upgrade the supervisors to Sup720-3BXL,

now my question is, all intefaces card have a PFC-3B added, do I need to upgrade all interface cards from PFC-3B to PFC-3BXL or can the interface cards have a mix of PFC-3B and PFC-3BXL's I the chassis

Re: PFC-3B vs PFC-3BXL

DFCs and PFCs is stated in the release notes and config guides for the related HW:

Configuration restrictions with PFC3BXL/DFCs:

-PFC3BXL and DFC3A-PFC3BXL functionality is restricted by the DFC3A: the

PFC3BXL functions as a PFC3A.

-PFC3BXL and DFC3B-PFC3BXL functionality is restricted by the DFC3B: the

PFC3BXL functions as a PFC3B.

-PFC3BXL and DFC3BXL-No restrictions.

In other words, okay to mix but expect the performance to be consistent with the what ever DFC is mixed in with the PFC3BXL. I hope that helps.
