Configuration Procedure
1. Create a VLAN on the Switch and add interfaces to the VLAN in trunk mode.
# Add GigabitEthernet 0/0/1 and GigabitEthernet 0/0/3 to a same VLAN in trunk mode.
The following takes the configuration of GigabitEthernet 0/0/1 as an example. The
configuration of GigabitEthernet 0/0/3 is the same as the configuration of
GigabitEthernet 0/0/1 and is not mentioned here.
<Switch> system-view
[Switch] vlan 1
[Switch-vlan1] quit
[Switch] interface gigabitethernet 0/0/1
[Switch-GigabitEthernet0/0/1] port trunk allow-pass vlan 1
[Switch-GigabitEthernet0/0/1] quit
2. Configure an observing port.
# Set GigabitEthernet 0/0/24 as the observing port.
<Switch> system-view
[Switch] observing-port 1 interface GigabitEthernet 0/0/24
3. Configure a mirrored port.
# Set GigabitEthernet 0/0/1 as a mirrored port.
[Switch] interface gigabitethernet 0/0/1
[Switch-GigabitEthernet0/0/1] port-mirroring to observe-port 1 inbound
[Switch-GigabitEthernet0/0/1] quit
4. Verify the configuration.
# Run the display port-mirroring command. You can check the configurations on the
observing port and mirrored port.
[Switch] display port-mirroring
Observe index 1 is set to interface GigabitEthernet0/0/24
Observe Type: Local
Interface GigabitEthernet0/0/1
Mirrored to: Observe index 1
Direction: inbound
Observe index 2 is not set to any interface
Observe index 3 is not set to any interface
Observe index 4 is not set to any interface
