This section lists limitations related to Cisco NX-OS Release 7.0(3)F3(3c).
■ The PTP process restart and system switchover accumulates high corrections for a few seconds. For more information, see CSCvg49023.
■ The LDP neighbor might flap on switchover in a scaled setup with many interfaces. Increase the discovery hello hold time for MPLS under the MPLS LDP configuration. For more information, see CSCvg71349.
■ A QoS policy having a MAC-based access list as a match in the class map does not work for IPv6 traffic. IPv6 traffic needs to be matched based on the IPv6 addresses and not the MAC address for QoS. For more information, see CSCvg21532.
■ CoPP (Control Plane Policing) cannot be disabled. If you attempt to disable it, an error message appears. For more information, see CSCvi09329.
■ 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. For more information, see CSCvc44819.
■ IPv4 traffic might drop when only IPv6 uRPF is enabled on the interface. For more information, see CSCvh99632.
