8.12 Mirroring configuration (SPAN/RSPAN)
Traffic mirroring is a feature of the router that allows for redirection of traffic from a specific port of the router
to another port of the same router (local mirroring) or to a remote device (remote mirroring).

traffic will be transmitted (in case of
using remote mirroring).

tx – mirroring only
outgoing traffic to the
specified VLAN;
