I. Background requirements

The Cisco two switches need to be virtual into a single switch (similar to a switch stack), to link two-tier access switches, and to provide high availability of network links. Such as:

  

For the two-layer switching 2960x needs to see the upper two n3k switches for a single device, the intermediate connection link does the link aggregation.

Second, configuration detailed

n3k_1 and N3K2 configurations remain consistent
