Configuration procedure
1. Configure Device A (the source device):
# Create a remote source group.
system-view
[DeviceA] mirroring-group 1 remote-source
# Create VLAN 2.
[DeviceA] vlan 2
[DeviceA-vlan2] quit
# Configure VLAN 2 as the remote probe VLAN, GigabitEthernet 3/0/1 as a source port, and
GigabitEthernet 3/0/3 as the reflector port in the mirroring group.
[DeviceA] mirroring-group 1 remote-probe vlan 2
[DeviceA] mirroring-group 1 mirroring-port GigabitEthernet3/0/1 both
[DeviceA] mirroring-group 1 reflector-port GigabitEthernet3/0/3
# Configure GigabitEthernet 3/0/2 as a trunk port that permits the packets of VLAN 2 to pass
through.
[DeviceA] interface GigabitEthernet3/0/2
[DeviceA-GigabitEthernet3/0/2] port link-type trunk
[DeviceA-GigabitEthernet3/0/2] port trunk permit vlan 2
[DeviceA-GigabitEthernet3/0/2] quit
# Disable the spanning tree feature on reflector port GigabitEthernet 3/0/3.
[DeviceA] interface GigabitEthernet3/0/3
[DeviceA-GigabitEthernet3/0/3] undo stp enable
[DeviceA-GigabitEthernet3/0/3] quit
2. Configure Device B (the intermediate device):
# Create VLAN 2.
system-view
[DeviceB] vlan 2
[DeviceB-vlan2] quit
# Configure GigabitEthernet 3/0/1 as a trunk port that permits the packets of VLAN 2 to pass
through.
[DeviceB] interface GigabitEthernet3/0/1
