We have one layer 3 switch. Configured monitor session to copy all the data in vlan 2 ports (RX only) to one sniffer port. There is one interface in this switch configured as a router interface. As I know router interface doesn't carry vlan information, but from what I have seen, the packet coming through router interface did get copied to sniffer port. So when the packet comes through router interface, the switch adds vlan 2 tag for that packet if they decide to route it to vlan 2? The SPAN just think it's incoming vlan 2 data, so it copys it to the sniffer port. Am I right?
