The capture parameters correspond to the Capture panel of the ValkyrieManager, and deal with configuration of the capture criteria and inspection of the captured data from a port.
Whether the port is enabled for capturing packets is specified by the P_CAPTURE parameter. Captured packets are indexed starting from 0, and are stored in a buffer that is cleared before capture starts. While on, the capture configuration parameters cannot be changed.
The capture parameter names all have the form PC_<xxx> and require both a module index and a port index. The per-packet parameters also use a sub-index identifying a particular packet in the capture buffer.
