1-3z Destination deviceThe destination device is the device where the monitor port is located. On it, you must create the remotedestination mirroring group.When receiving a packet, the destination device compares the VLAN ID carried in the packet with the IDof the probe VLAN configured in the remote destination mirroring group. If they are the same, the deviceforwards the packet to the monitoring device through the monitor port.To make the port mirroring function work properly, before configuring bidirectional traffic mirroring on aport in a mirroring group, you need to use the mac-address mac-learning disable command on thesource device, intermediate devices, and destination device to disable the MAC address learningfunction for the remote port mirroring VLAN. For more information about the mac-addressmac-learning disable command, refer to MAC Address Table Management Commands in the SystemVolume.Configuring Local Port MirroringConfiguring local port mirroring is to configure local mirroring groups.A local mirroring group comprises one or multiple mirroring ports and one monitor port. These portsmust not have been assigned to any other mirroring group.Follow these steps to configure a local mirroring group:To do… Use the command… RemarksEnter system view system-view —Create a local mirroring group mirroring-group groupid local RequiredIn system viewmirroring-group groupidmirroring-port mirroring-port-list{ both | inbound | outbound }interface interface-typeinterface-number[ mirroring-group groupid ]mirroring-port { both | inbound |outbound }ConfiguremirroringportsIn interface viewquitRequiredYou can configuremirroring ports in amirroring group.In system view, you canconfigure a list ofmirroring ports to themirroring group at a time.In interface view, you canassign only the currentport to the mirroringgroup.
