Destination device
Destination device contains destination mirroring port, and remote destination port
mirroring groups are created on destination devices. Upon receiving a mirrored packet,
the destination device checks to see if the VLAN ID of the received packet is the same
as that of the remote mirroring VLAN of the remote destination port mirroring group. If
yes, the destination device forwards the packet to the monitoring device through the
destination mirroring port.
1.1.3 Other Functions Supported by Port Mirroring
In addition, in a port mirroring group, a destination port can monitor multiple source
ports simultaneously in the mirroring group.
