How to Configure Static MAC Address Entries on Huawei BRAS ME60?
After a static MAC address entry is configured on Huawei Router BRAS ME60, packets with the destination MAC address matching the entry are forwarded from the specified outbound interface. This configuration protects a device from attack packets with forged MAC addresses.
Usage Scenario
If a network has fixed users or a server connects to a switch on the network, static MAC address entries need to be configured on the switch to prevent hackers from attacking the switch or the server. On the network shown in Figure 1, you can configure a static MAC address entry on the switch containing the MAC address of the server so that the switch forwards packets destined for the server through only a specified interface. This configuration prevents hackers from attacking the server using forged MAC addresses and from stealing information from the server, as well as ensures the communication between users and the server.
Pre-configuration Tasks
Before configuring a static MAC address entry, connect interfaces and set their physical parameters to ensure that the physical interface status is Up.
Procedure
- Run system-view
The system view is displayed.
- Use either or both of the following methods to add static MAC address entries.
- Run the mac-address static mac-address interface-type interface-number vlan vlan-id command to add VLAN-based static MAC address entries.
Run the mac-address static mac-address interface-type interface-number vsi vsi-name [ pe-vid pe-vid [ ce-vid ce-vid ] ] command to add VSI-based static MAC address entries.
- Run the mac-address static mac-address interface-type interface-number vlanif vlan-id vsi vsi-name command to configure static MAC address entries for VSIs bound to the VLANIF interface.
NOTE:
Static MAC address entries take precedence over dynamic MAC address entries.
- Run commit
The configuration is committed.
Checking the Configurations
Run the following commands to check the previous configurations.
Run the display mac-address [ mac-address ] [ vlan vlan-id | vsi vsi-name ] [ verbose ] command to check detailed information about MAC address entries.
Run the display mac-address static [ vsi vsi-name | { vlan vlan-id | interface-type interface-number } * ] command to check static MAC address entries.
Run the display mac-address command to view all MAC address entries. The command output shows the static MAC address entry with static in the Type field.

interface. VLAN mapping can only be configured on a trunk or hybrid interface.
[HUAWEI-GigabitEthernet0/0/1] qinq vlan-translation
enable //On a fixed device, VLAN translation must be
enabled first. This configuration is not required on a modular device.
[HUAWEI-GigabitEthernet0/0/1] port vlan-mapping vlan 2 map-vlan 200
Configuring N to 1 VLAN Mapping
N to 1 VLAN mapping allows the switch to
map a range of VLAN IDs to an S-VLAN ID.
For example,
configure the switch to map VLANs 3, 4, 5, and 6 in packets entering
GE0/0/1 to VLAN 200.

Why the Fiber link fails to created between two Huawei DWDM device?
When you encounter fiber link fails to created between two NEs Huawei OTN network devices, you can analyze them in two step.
First,check the usage of the port as per below steps on the NMS:
Open NE explorer.
Open Signal view diagram.
Locate Huawei OSN 6800 OSN 8800 board which is in question.
Right click the board & choose (Show relevant fibers).
Check if any fiber is configured on that port.
If it is configured,delete it.
If no fiber is found configured on the port , carry out the second step of processing:
In Fiber/Cable Synchronization (Inventory > Fiber/Cable/Microwave Link > WDM Fiber/Cable Synchronization), check whether the desired port is found or not.
If yes, try to re-synchronize it.
If no, proceed into the steps below to fix the issue:
1.Use Navigator to login into particular NE with the Error issue.
2.Use the command line "cfg-get-fibermgr:0,0,0,0" to list out all the logical fiber connection in that NE.
3.A list of logical fiber connection will be display.
For example: 0x00FDEFD 6 11 0x0WFDGRDF 8 4
Source Address slot port Sink Address slot port
4.Use command "cfg-del-fibermgr: " to delete desire port.Make sure to get the correct information before proceeding to delete the logical fiber.
5.If the error shows it’s the source, then check the source address, and if it’s sink then check the sink address.
6.Once the logical fiber is deleted, the NE on the NMS will show the red arrow logo on the NE icon which indicate changes are successfully made and require to synchronize.
7.Proceed to "Synchronize the NE Configuration" to synchronize the NE.
8.Once the NE is synchronized, the logical fiber connection should be able to be created as it needed to be.
Root Cause
the root cause is due to incomplete deletion of the logical fiber connection/trail
Solution
Clear the port by delete the associated fiber using navigator

How to Configure 10G LAN & 10G WAN in Huawei DWDM network?
What are the differences between 10GE LAN and 10GE WAN services?
According to IEEE 802.3ae, compared with 10GE LAN services,10GE WAN services involve an additional process in which signals are encapsulated into standard SDH/SONET frames. In other words, 10GE WAN services are processed in a similar way as how Huawei STM-64 service board are processed in a Huawei WDM/OTN system.The most direct difference between 10GE LAN and 10GE WAN services is that they have different signal rates.
How do we configure 10GE LAN and 10GE WAN services?
Let's take a look at the steps for configuring 10GE WAN services.
About the 10G LAN there are 2 types of port mapping ((bit transparent mapping and MAC transparent mapping))
What is the difference between bit transparent mapping and MAC transparent mapping?
In bit transparent mapping (11.1G) mode, the OTU frame frequency is increased to ensure the encoding gain and error correction capability of the FEC function.Therefore, the service rate is OTU2e,which is higher than OTU2. This mapping mode is recommended for interconnection between Huawei devices.
In MAC transparent mapping (10.7G) mode, the GFP-F encapsulation mode is used to map 10GE MAC frames into OTU2 signals.
This mapping mode provides a standard service rate and therefore facilitates interconnection between Huawei devices and peer devices.
