I am starting to bring up a Nexus 5K/2K configuration. Our Cisco SE has told us that we need to VPC connections between each fo the 5K pairs. We will also need a vpc keepalive connection. He is suggesting that we use the management interface for this. Although the cisco docs I have say this interface isnt available, I know that it does work. Are the ports labeled L1 and L2 available to use for a VPC Keepalive connection ? Would prefer not to sacrifice the management ethernet port for this task.
