86 CHAPTER 10: PORT MIRRORING CONFIGURATION
■ A remote source mirroring group can have only one reflector port.
■ A port can be configured as a reflector port only when it operates with the
following settings being the defaults: operation mode (half duplex/full duplex),
port speed, and MDI setting.
■ Use a remote port mirroring VLAN for remote port mirroring only.
■ Only existing static VLANs can be configured as remote port mirroring VLANs.
To remove a VLAN operating as a remote port mirroring VLAN, you need to
restore it to a normal VLAN first. A remote port mirroring group gets invalid if
the corresponding remote port mirroring VLAN is removed.
■ A port can belong to only one port mirroring group. A VLAN can be the remote
port mirroring VLAN of only one port mirroring group.
■ Disable MAC address learning in remote port mirroring VLANs to ensure the
functionality of remote port mirroring.
Configuring a Remote
Destination Port
Mirroring Group
You need to configure destination ports and remote port mirroring VLAN for a
remote destination mirroring group.
Follow these steps to configure a remote destination port mirroring group:
To do... Use the command... Remarks
Enter system view system-view -
Create a remote port mirroring VLAN and
enter VLAN view

With count being 0,
MAC address learning is
disabled in target
remote port mirroring
VLAN.
