Operation Manual – Port MirroringH3C S3610&S5510 Series Ethernet Switches Chapter 1 Port Mirroring Configuration1-6Note:z All the ports of a remote source mirroring group belong to a single device. A remotesource mirroring group can contain only one reflector mirroring port.z A reflector port cannot be a member port of the current mirroring group, anaggregation port and cannot be configured with the QinQ function. It is required tobe an access port and belong to the default VLAN.z It is not recommended to add the source ports to a remote VLAN, which can be usedfor remote mirroring only.z It is not recommended to connect network cable to the reflector port and to configurethe following functions on this port: STP, RSTP, MSTP, 802.1x, IGMP Snooping,static ARP and MAC address learning, otherwise, the mirroring function may beaffected.z A port can be configured as a reflector port only when it operates with the followingsettings being the defaults: operation mode (half duplex/full duplex), port speed,MDI setting. Conversely, these settings cannot be modified once a port isconfigured as a reflector port.z Only existing static VLANs can be configured as remote port mirroring VLANs. Toremove a VLAN operating as a remote port mirroring VLAN, you need to restore it toa normal VLAN first. A remote port mirroring group gets invalid if the correspondingremote port mirroring VLAN is removed.z A port can belong to only one port mirroring group. A VLAN can be the remote portmirroring VLAN of only one port mirroring group.1.3.2 Configuring a Remote Destination Port Mirroring GroupFollow these steps to configure a remote destination port mirroring group:To do… Use the command… RemarksEnter system view system-view —Create a remotedestination port mirroringgroupmirroring-group group-idremote-destination RequiredConfigure the remote portmirroring VLAN for the portmirroring groupmirroring-group group-idremote-probe vlan rprobe-vlan-id Required
