Thank you for asking this question in the support community!
The Configuring Packet Capture in AOS guide and the AOS Feature Matrix - Product Feature Matrix explain that this feature was released in firmware version R10.1.0. Therefore, you would need to Upgrading Firmware in AOS to utilize this feature.
I hope that makes sense, but please do not hesitate to reply to this post with any additional questions or information. I will be happy to help in any way I can.
