Cisco says:

"A source VLAN is a VLAN monitored for network traffic analysis. VLAN-based SPAN (VSPAN) uses a VLAN as the SPAN source. All the ports in the source VLANs become source ports. "

Is this true even if the ports are located on different switches?

I have ports belonging to the same VLAN scattered over 4 switches.

If I set this VLAN as the SPAN source , will I be able to monitor traffic of all the ports belonging to this VLAN even if they are located on different switches?

chears!

VLAN-based SPAN is for the switch in question. Depending on what switch you have/Software versions, you can use Remote SPAN(RSPAN) to acheive what you are asking
