Figure 49 Local port mirroring implementation
As shown in Figure 49 , the source port Ethernet 1/1 and monitor port Ethernet 1/2 reside on the same
device. Packets received on Ethernet 1/1 are copied to Ethernet 1/2, which then forwards the packets to
the data monitoring device for analysis.
Configuring local port mirroring
Local port mirroring takes effect only when the source ports and the monitor port are configured.

Creating a local mirroring group
Step Command Remarks
1. Enter system view. system-view N/A
2. Create a local mirroring
group.
mirroring-group group-id local
By default, no local mirroring
group exists.
Configuring source ports for the local mirroring group
You can configure a list of source ports for a mirroring group at a time in system view, or assign a port
to it as a source port in interface view. To assign multiple ports to the mirroring group as source ports in
interface view, repeat the operation.
