We intended to upgrade 10G network from existing 7606 Switch.
There're 2 modules, WS-X6704-10GE and WS-X6708-10G-3CXL/WS-X6708-10G-3CXL3C.
if we select WS-X6708-10G-3CXL/WS-X6708-10G-3CXL3C... all ports using would consume 80GB logically, but 40GB fabric connection only in spec.
did any recommendation for upgrade 10G network ? I saw in supervisor 2, there're something like SFM to increase the backplane, did sup720 have similar things? or the module originally only 40GB switch fabric ... no way to do even adding SFM.
XENPAK-10GB-ZR could be supported now? i saw from the cisco doc, it mention "Not Available today"..
anyone could confirm me this?
Also, how about if i get 6500 series for 10G? would there're no oversubscription issue?
