This section provides information for troubleshooting SD-AVC problems. If this information does not provide a solution, contact Cisco TAC for assistance.
Communication with Devices by TCP
The SD-AVC Network Service uses TCP to communicate with the devices that it manages, over port 50000. In the SD-AVC Dashboard, if the Connectivity page shows any type of connectivity warning, check FTP connectivity on UDP port 50000. If no problem is found with connectivity, contact Cisco TAC.
NBAR Activation on Interfaces
On devices in the network that are using SD-AVC, the NBAR2 component must be active on any interface that processes network traffic, in order to report on traffic handled by the interface. For details, see Configuration Prerequisites: Network Devices Using SD-AVC.
Without this, the device will not report on any traffic on that interface. This can cause a red X icon warning in the SD-AVC Dashboard, on the Connectivity page, in the Traffic Health column.
