Why vPC peer-link must be 10GBE? Can we use 40/100GBE or 1GBE?

Hi Sir,

At one document <Design and Configuration Guide: Best Practices for Virtual Port Channels (vPC) on Cisco Nexus 7000 Series Switches Revised: August 2014 > , Peer-link : Link used to synchronize the state between vPC peer devices. It must be a 10-Gigabit Ethernet link. 

I know no much traffic forward on peer-link( no need high BW), but port-speed have 1G speed , 40G speed, why need to say must be a 10G link on peer-link?

Thanks for reading.

Lance.

Hi Lance,

I have Nexus 9300 and, I used 40G links for VPC. It works just fine.
