Port Mirroring
Configuring a Remote
Source Mirroring Group
Follow these steps to configure a remote port mirroring group

■ All ports in a remote mirroring group belong to the same device. A remote
source mirroring group can have only one outbound mirroring port.
■ The outbound mirroring port cannot be a member port of the current
mirroring group.
■ It is not recommended to add the source ports to a remote VLAN, which can
be used for remote mirroring only.
■ It is not recommended to configure STP, RSTP, MSTP, 802.1x, IGMP Snooping,
static ARP and MAC address learning on the outbound mirroring port;
otherwise, the mirroring function may be affected.
■ 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.
