6509 Sup720 and 67xx line cards memory

[jstrine]

I am in the process of ordering a 6509 with Sup720-3B and had some memory questions.

There will be 6748-GE-TX, 6724-SFP, and 6704-10GE cards in the chassis. Right now we will use centralized forwarding. I understand the WS-F6700-CFC card is required for each of those line cards to support this. Is there any memory required in addition to the CFC? I have seen the MEM-XCEF720-256M and MEM-XCEF720-512M mentioned in some quotes, but the information I find on Cisco's website seems to indicate these are only needed with the DFC daughter cards.

Also, where specifically are the supervisor DRAM memory modules used? For example, I have MEM-MSFC2-512MB and MEM-S2-512MB on some quotes but am having a hard time figuring out what specifically they are memory for. From what I can gather, there needs to be DRAM memory for the SP, RP, and PFC3 card. The MEM-MSFC2-512MB is for the SP and RP, right? And the MEM-S2-512MB is for the PFC3, right? Or am I just really confused at this point?

Thanks for the help.

All 67xx series linecards use exactly the same type of memory as Sup 720 memory. So, in this case it's MEM-XCEF720-????.

Even without DFC, I believe 67xx series still need local memory.

MEM-S2-???? and MEM-MSFC2-???? are only for "legacy" supervisors and MSFC cards (e.g. Sup 2 + MSFC daughter card).

HTH.
