So I've been reading Data Center Access Design with Cisco Nexus 5000 Series Switches and 2000 Series Fabric Extenders and Virtual PortChannels and came across a table that says dual homing FEXs to 5Ks is not supported when 2 5Ks and 2 7Ks are in a dual sided vPC topology.
Table 2 on page 8 of http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9670/C07-572829-01_Design_N5K_N2K_vPC_DG.pdf
No Support for Fabric Extender DualHomed Design. I understand enhanced vPC is not supported on 7Ks yet. But it is on 5Ks. So if I dual home my 5Ks to 7Ks in a cross bar dual sided vPC topology, can I not dual home my FEXs to the 2 5Ks in a cross bar manner? Also, it says port channel teaming is not supported from servers. So does that mean if I have a server, can I not vPC it to both 5Ks using LACP or regular port-channel?
Maybe I'm reading it wrong, but would love some clarification!
