When you use the command
SW(config)# monitor session session-number filter vlan vlan-range
It is monitoring the range of vlans you have defined with this command.
MDF-ROC3(config)# monitor session 11 filter vlan 1 - 3 , 229
It is monitoring the from vlan 1 to vlan 3 and the vlan 229
The word "filter" in this command means:"select the VLANs you want to forward"
Nothing is perfect, and you'll find a few more. Check it all with pcaps and debugs, that's the approach.
Not sure what platform OCG is based on. Anyways, you might find the same answer and Ing_Percy gave here:
I prefer to lean on the master command line reference index to get me to the documentation for any particular command (rather than what is printed in OCGs). https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/mcl/allreleasemcl/all-book.html
Limits SPAN-source traffic to specific VLANs.
The filter keyword is not supported on the Cisco 2600 series or the Cisco 3600 series routers.
According the CCIE Routing & Switching V5 volume 1, when you configuring a Trunk port as a SPAN source you can filter (remove ) VLANs as per the page number 26
" We also filter (remove) VLANs 1, 2, 3, and 229 from the traffic coming from the fa0/19 trunk port. "
It is a mistake, this command will specify the vlans to be monitored
