VPC and VXLAN

[Hamada Ahmed]

I want to ask question,

in case we VPC with VXLAN, 

there is command "VPC vne peer-link-vlan X

what this command do?

[Sergiu.Daniluk]

The vpc nve peer-link-vlan command needs to be used only in the Cisco Nexus 5600 Series switches. Cisco Nexus 5600 Series switches encapsulate VXLAN packets over the vPC Peer-Link with the configured VLAN as the outer-vlan tag while Cisco Nexus 7000,7700,9000 Series switches decapsulate VXLAN packets coming from the core and the decapsulated packet is bridged across the vPC Peer-Link since they use ASM/SSM protocols.

Good question - I was used traditional vPC, Looking at the documentation nexus os 9.2 has some features.
