The source device sends one copy of packets received on the source port Ten-GigabitEthernet
1/0/1 to the tunnel interface (serving as the monitor port in the local mirroring group created on
the source device), which then forwards them to the tunnel interface on the destination device
through the GRE tunnel. The destination device receives the mirrored packets from the physical
interface (serving as the source port in the local mirroring group created on the destination device)
of the tunnel interface, and then sends one copy of the packets to the monitor port
Ten-GigabitEthernet 1/0/2. Ten-GigabitEthernet 1/0/2 forwards the packets to the data
monitoring device. For more information about GRE tunnels and tunnel interfaces, see Layer 3—IP
Services Configuration Guide.

Configuring local port mirroring
Local port mirroring takes effect only when the source ports or CPUs, and the monitor port are
configured.
