Disabling the MAC address learning function when configuring remote mirroring on S series switches

26

For S series switches, after Layer 2 remote port mirroring is configured, mirrored packets are forwarded to intermediate devices through a VLAN and then to the monitoring device by following the general Layer 2 forwarding process. The mirrored packets cannot be forwarded according to the MAC address tables on the intermediate devices because their destination MAC addresses are the same as those of the original packets but not the MAC address of the monitoring device. The mirrored packets must be treated as unknown unicast packets and broadcast to all interfaces in the VLAN. The mirrored packets can be forwarded to the monitoring device in broadcast mode as long as the MAC address table of the VLAN contains no entry matching the destination MAC addresses of the mirrored packets.
If the mirrored packets cannot reach the monitoring device, the MAC address tables on the intermediate devices may contain entries matching the destination MAC addresses of the mirrored packets. If this occurs, the mirrored packets are forwarded according to the MAC address tables and cannot reach the monitoring device. In this case, you need to run the mac-address learning disable command in the VLAN view to disable the MAC address learning function.

How to disable MAC address learning on S series switches
For S series switches (except the S1700), you can use the following methods to disable MAC address learning: 1. Disable MAC address learning on an interface. [HUAWEI] interface gigabitethernet0/0/3 [HUAWEI-GigabitEthernet0/0/3] mac-address learning disable 2. Disable MAC address learning in a VLAN. [HUAWEI] vlan 2 [HUAWEI-vlan2] mac-address learning disable

Is MAC address of virtual machine learned by S series switch correct?
It is normal that S series switches (except S1700 switches) can learn MAC addresses of VMs. MAC address learning is the prerequisite for communication.
