I have a Cisco Nexus Datacenter solution with this design:
Every Nexus 5K is connected with every Nexus 2K with a Port-Channel and vPC.
What is the best way,to keep the configurations of the nexus switches synchronous? I have no DCNM (Mgmt.-Tool).
My problem is if I configure for example a Nexus2K-host port on one Nexus 5K, the change has no effect. Only when I make the same change on
the second N5K the port-config really changes.
You can use config Sync:
