hello,


We have to N5K with N2K fex's. We are dual homing the fexs to the N5Ks setting up VPC between the two N5Ks and the each fex.  Is it normal to see every interface on each FEX as   part of a VPC?




See output below:

Hi I asked Cisco a while  ago the same question... the response was:

"As for VPC number 201728 and higher, this is normal behavior when you configure on N5K FEX fabric ports as vPCs."
