Shulou(Shulou.com)06/01 Report--

For N5K can meet the following topology connection FEX, but when testing, always found that FEX can not connect successfully, only one N5K interface connection N2K can display Online.

Reason: although N5K can support this situation, you need to establish a vPC,N2K before you can display Online on both N5K, because for N2K, the upstream is treated as a device.

Before completing the above tests, try static Pinning mode and Port-channel mode.
