This section lists limitations related to Cisco NX-OS Release 7.0(3)F2(2).
§ When entering the install all command to upgrade from 7.0(3)F2(1) to 7.0(3)F2(2), not all modules are upgraded. Enter the install command and reload the modules one-by-one.
§ IPv4 traffic might drop when only IPv6 uRPF is enabled on the interface.
§ 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.
§ 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.
§ IPv4 and IPv6 throughput is not the same when both have an equal amount of traffic.
