I am trying to understand how much data is flowing through a specific port on a Cisco (Stratix) switch. I have set up Port Mirroring so that I can capture the traffic on the target port via Wireshark. When viewing the Wireshark recording, I can see the network traffic in bits/s when viewing the Protocol Hierarchy Statistics. The data rate displayed in the 'Frame' row is 72Mb/s while the 'Ethernet' row shows 865kb/s. [![Wireshark Protocol Hierarchy Statistics screenshot](https://i.stack.imgur.com/YBGc8.png)].

Can someone send me to school and help me understand which field I should be looking at to evaluate switch port data throughput? My target switch port is a 1GB/s port and I am trying to determine how close to it's throughput limit I am.
