The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
This section provides information for troubleshooting SD-AVC problems. If this information does not provide a solution, contact Cisco TAC for assistance.
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.
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.
