tcpdump from client to VIP and Self Ip to Pool

Hello,

As Juergen_Mang said, the "P" option allows you to capture both sides.

"you can use the p interface modifier with the n modifier to capture traffic with TMM information for a specific flow and its related peer flow. The p modifier allows you to capture a specific traffic flow through the BIG-IP system from end to end,"

Besides show the traffic in the wireshark using the flow option to isolate traffic as you need.

navigate to Statistics > Flow Graph, you will find an output similar to the below one that shows client side and server side:
