Plug the MGMT0 ports into a separate management switch and then they will all be CFS adjacent. You don't want to connect the mgmt ports back-to-back for vPC peer keepalive on 7K anyways. If your primary supervisor goes down the standby supervisor won't be vPC keepalive adjacent with the other side and the vPC can fail.

Subject: Nexus 7000 CFS and NTP/TACACS+
Hello all,
I've been unable to find documentation on this regarding the specific vrf that cfs uses and if that can be changed for other services. I know that vPC uses CFS.
We have 10 Nexus 7K's, mix of 7700 and 7000s, configured in 5 vPC pairs. The vPC keep-alive is set up via management interfaces.
I'm trying to use CFS to distribute some applications such as NTP and TACACS+, however the distribution only gets from one peer to the other, it won't cross over to any other pairs.
When I run a show cfs peers, I
see the management IP's of the local pair devices. Is it possible to run CFS over the management VLAN interface so they can all peer with one master Nexus?
