From Documentation:
The switch monitors network activity by copying all traffic inbound and outbound on the specified interfaces to the designated monitoring port, to which a network analyzer can be attached.
If a tagged packet arrives on a monitored port, the packet will remain tagged when it goes out a monitored port even if that port is configured as untagged. If the packet is untagged, it will remain untagged going out the monitor port. The monitor port state (tagged or untagged) does not affect the tagging of the packet. However, egress mirroring does not reflect the tagged or untagged characteristic to the mirror port, instead it reflects the tagged or untagged characteristic of the mirror port.
So it is possible, but you will only receive the flood traffic for that vlan, not the unicast traffic that is not intended for the mirrored interface.
