After doing some more research I answered my question. Here is what I found:
There are different commands that need to be run on the source switch(es) and the destination switch.
Source switch:
monitor session 2 source vlan 101
monitor session 2 destination remote vlan 902
Destination switch:
monitor session 2 source remote vlan 902
monitor session 2 destination int gi7/40
The commands for the source switch(es) must be put on every switch that will have source data on VLAN 101.
Hope this helps someone.
