Unfortunately, I am in C code of the VPP plugin and all I have for span src and dst is names of the interfaces, "TenGigabitEthernet3/0/0", "TenGigabitEthernet3/0/1". Is there an unformat trick to convert the name to sw_if_index - I see unformat_vnet_sw_interface but I don't have access to any unformat_input_t*. Am using C API for the first time.

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
