Not Receiving Inbound Traffic on RSPAN Destination

Hello.  I have rspan setup, but noticed on my workstation running Wireshark I'm only receiving outbound traffic from the source device.  Without luck I've tried rspan source monitor-both eth 2/1/20 as well as rspan source monitor-in eth 2/1/20 AND rspan source monitor-out eth 2/1/20.  I do not have a capture or display filter set on Wireshark.  Below is what I have configured.  I was wondering if someone could see what I'm missing?  Thanks.

Access SW with source device

rspan-vlan 3100
tagged lag 1      [lag 1 is trunk to Core SW]
rspan destination lag 1
rspan source monitor-in ethe 2/1/20
rspan source monitor-out ethe 2/1/20

int eth 2/1/20
