To better analyze live traffic on Cascade Shark from Cascade Pilot you should:

Apply a View on the live interface and then start a Capture Job on the capture port to analyze traffic later.

Start a Capture Job on the capture port with a BPF filter and apply a View on the live interface for the same capture job.

Start a Capture Job on the capture port, apply a View on the live interface and create a trace clip for the time window of interest.

Never create a Capture Job to prevent packet drops.
