Step Command Remarks
3. Add ports to the port mirroring
group as mirroring ports.
• (Approach I) In system view::
mirroring-group group-id
mirroring-port mirroring-port-list { both
| inbound | outbound }
• (Approach II) In interface view:
a. interface interface-type
interface-number
b. [ mirroring-group group-id ]
mirroring-port { both | inbound |
outbound }
c. quit
Use either approach.
You can add ports to a
port mirroring group as
mirroring ports in either
system view or
interface view.
In system view, you can
add multiple ports to a
port mirroring group at
a time. While in
interface view, you can
add only the current
port to a port mirroring
group.
4. Add a port to the mirroring
group as the monitor port.
• (Approach I) In system view:
mirroring-group group-id monitor-port
monitor-port-id
• (Approach II) In interface view:
a. interface interface-type
interface-number
b. [ mirroring-group group-id ]
monitor-port
Use either approach.
You can add a monitor
port to a port mirroring
group in either system
view or interface view.
They achieve the same
purpose.
NOTE:
•
A local mirroring group is effective only when it has both mirroring ports and the monitor port
configured.
• To make sure that the mirroring function works properly, do not enable STP on the monitor port of a
mirroring group.
• A port mirroring group can contain multiple mirroring ports and only one monitor port.
• A port can belong to only one port mirroring group.
Configuring remote port mirroring
NOTE:
•
If the GARP VLAN Registration Protocol (GVRP) is enabled, GVRP may register the remote probe VLAN
to unexpected ports, resulting in undesired duplicates. For more information about GVRP, see
Layer 2
— LAN Switching Configuration Guide.
• The router supports remote mirroring only when the system working mode is SPC or SPE.
Configuration prerequisites
Before configuring remote port mirroring, create a static VLAN to be configured as the remote probe
VLAN later.
