I see https://docs.fd.io/vpp/17.04/span_doc.html The link about says this is the api: : sw_interface_span_enable_disable I call the API in C code as: sw_interface_span_enable_disable ("TenGigabitEthernet3/0/0", "TenGigabitEthernet3/0/1", 3, true); When I compile the code I get this error: error: implicit declaration of function 'sw_interface_span_enable_disable' is invalid in C99 [-Werror,-Wimplicit-function-declaration] What header file do I need to include? Span.h doesn't include this api. Hemant
