Whether observing-port of S-series switch can distinguish the mirrored traffic of different VLANs

For S-series switches, because the mirrored traffic is copied directly from the original traffic, the traffic mirroring to the observing port is related to whether the port carry the VLAN tag and the direction of mirrored port.
- Inbound of mirroring traffic: For the Access port type, because the original traffic do not carry VLAN tag, the mirrored traffic to the observing port do not have VLAN tag; For Trunk type port, because the original traffic carry VLAN tag, the mirrored traffic to the observing port has a VLAN tag too; The hybrid port has both of the above two cases.
- Outbound of mirroring traffic: For some switches, the mirroring action occurs before adding / stripping VLAN tags, because the original traffic from the device before the general release with a VLAN tag, the mirror to the observation port has a VLAN tag too; For another Part of the switch, the mirror action occurs after adding / stripping VLAN tags, so whether mirroring to the observing port carry VLAN tag is same as inbound of mirroring traffic style.
