Each remotesource mirroring group can be configured with only one reflector port.z The reflector port cannot be a member port of an aggregation group, or a portenabled with LACP or STP. It must be an access port and cannot be configuredwith the functions like VLAN-VPN, port loopback detection, packet filtering, QoS,port security, and so on.z It is recommended not to configure the VLAN mapping and the selective QinQfunction on the reflector port; otherwise, port mirroring may not function properly.z You cannot modify the duplex mode, port rate, and MDI attribute of a reflector port.z Only an existing static VLAN can be configured as the remote-probe VLAN. Toremove a remote-probe VLAN, you need to restore it to a normal VLAN first. Aremote port mirroring group gets invalid if the corresponding remote port mirroringVLAN is removed.z Do not configure a port connecting the intermediate switch or destination switch asthe mirroring source port. Otherwise, traffic disorder may occur in the network.II. Configuration on a switch acting as an intermediate switch1) Configuration prerequisitesz The trunk ports and the remote-probe VLAN are determined.z Layer 2 connectivity is ensured between the source and destination switches overthe remote-probe VLAN.2) Configuration procedure
