This section lists limitations related to Cisco NX-OS Release 7.0(3)F3(2).
■ CoPP (Control Plane Policing) cannot be disabled. If you attempt to disable it, an error message appears.
■ The skip CoPP policy option has been removed from the Cisco NX-OS initial setup utility because using it can impact the control plane of the network.
■ IPv4 traffic might drop when only IPv6 uRPF is enabled on the interface.
■ The sum of queue limits in a policy is not checked and therefore can exceed 100%. Make sure to check the limits while creating the queuing policy.
■ VXLAN over vPC is not supported.
o VLAN list needs to be mutually exclusive between VXLAN and vPC
o vPC peer-link should not have VXLAN VLANs in the allowed VLAN list
