That is what I've found:
Can You Configure SPAN on an EtherChannel Port?
An EtherChannel does not form if one of the ports in the bundle is a SPAN destination port. If you try to configure SPAN in this situation, the switch tells you: Channel port cannot be a Monitor Destination Port Failed to configure span feature You can use a port in an EtherChannel bundle as a SPAN source port.
