VPC & Port-Channel
In DC1
N7K-3 & N7K-4 configure port-channel with Nexus-11 & Nexus-2 as in
diagram, (i am excluding LACP primary on N7K-3,4 , i am excluding this)
Make sure N7K-3 is both operational and role primary.
Downstream port channel must meet the following requirements:
. (LACP i am excluding this)
. Trunk Port
. Allow Vlan 30,40,70 only
. Jumbo Frame
You may assign any domain number per your choice.
Device name inerface port-channel

N7K-3 e2/9 20
N7K-4 e2/6 10
