Hello!

I need to know why WS-X6704-10G module requires 512-MB DRAM with a WS-F6700-CFC? I find it in release notes http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/15-1SY/release_notes.html#pgfId-4765684. Cisco says this is a bug https://tools.cisco.com/bugsearch/bug/CSCtk82279 but i don't have permissions to view. 

WS-F6700-CFC is not memory upgradable, so we need to replase it with DFC? This is hardware limitation? This card allocate 256 MB DRAM and no memory options. We want to use this module with SUP720 and SUP 2T in hard mode, it will be about 60Gbit in full duplex for all four ports. Any restrictions for that with CFC? 

Can someone help please?
