1 MAC Address Table ConfigurationAbout This Chapter

Each workstation or server that is connected to the Ethernet interface on a device has a uniqueMedium Access Control (MAC) address. The MAC address table on the device contains theMAC addresses of all the other devices that are connected to this device. The MAC address tableis used for data forwarding.

1.1 MAC Address Table IntroductionA MAC address table is an interface-based Layer 2 forwarding table. It stores information aboutthe MAC addresses learned by the device.1.2 Configuring the MAC Address Table Based on the VLAN and Layer 2 InterfaceIf user networks are connected through Layer 2 devices and do not forward data through Layer3 routing, you can configure a MAC address table based on Layer 2 interfaces and VLANs fordata forwarding. Thus, user networks can communicate with each other.1.3 Configuring the MAC Address Table Based on the VSI and Layer 3 InterfaceIf user networks are connected through a Virtual Private LAN Service (VPLS) network, you canconfigure a MAC address table based on Layer 3 interfaces and Virtual Switch Instances (VSIs).Thus, user networks can communicate with each other.1.4 Configuring the Aging Time of a MAC Address TableAfter the network topology changes, dynamic MAC address entries are not automaticallyupdated in time. As a result, a device cannot learn new MAC addresses and thus user trafficcannot be normally forwarded. To addresses this problem, you need to configure the aging timeof MAC address entries.1.5 Maintaining MAC Address TableThis section provides commands used to maintain MAC address tables, including the commandthat is used to delete dynamic MAC address tables.1.6 Configuration ExamplesThis section lists networking requirements, configuration roadmap, and data preparation todescribe the typical application scenarios of MAC address tables, and provides relatedconfiguration files.

1.1 MAC Address Table IntroductionA MAC address table is an interface-based Layer 2 forwarding table. It stores information aboutthe MAC addresses learned by the device.

1.1.1 MAC Address Table OverviewMAC address entries can be classified into dynamic entries, static entries, and blackhole entries.All workstations and servers connected by the Ethernet interfaces of a device have unique MAC(Medium Access Control) address. The MAC address table on the device contains theinformation about the MAC addresses of all the devices connected by this device.MAC address entries are classified into the following types: l Dynamic entries

Dynamic entries are learned and stored on interface boards. The dynamic entries expireand are lost after hot swapping or interface-board resetting, or device rebooting.

l Static entriesStatic entries are configured by users. They are automatically delivered to each interfaceboard. Static entries do not expire and are not lost after device rebooting, hot swapping, orinterface-board resetting.

l Blackhole entriesBlackhole entries, configured by users, are used to discard frames containing specifiedMAC address. They are delivered to each interface board. The blackhole entries do notexpire and are not lost after device rebooting, hot swapping or interface-board resetting.

1.1.2 MAC Addresses Learning Limit Supported by the NE80E/40EAs the capacity of a MAC address table is limited, it is necessary to specify the maximum numberof MAC addresses to be learned and limit the rate at which MAC addresses are learned. In thismanner, you can control the number of access users and prevent malicious users from attackinguser devices and networks through MAC addresses.For the MAC address learning limit, refer to the HUAWEI NetEngine80E/40E RouterConfiguration Guide - Security.

1.2 Configuring the MAC Address Table Based on theVLAN and Layer 2 Interface

If user networks are connected through Layer 2 devices and do not forward data through Layer3 routing, you can configure a MAC address table based on Layer 2 interfaces and VLANs fordata forwarding. Thus, user networks can communicate with each other.



2

1.2.1 Establishing the Configuration TaskBefore configuring a MAC address table based on Layer 2 interfaces and VLANs, familiarizeyourself with the applicable environment, complete the pre-configuration tasks, and obtain therequired data. This can help you complete the configuration task quickly and accurately.

Applicable EnvironmentNOTE

The ATM interface cannot be configured on the X1 and X2 models of the NE80E/40E.

Generally, a device automatically creates MAC address tables by learning source addresses.To enhance the security of an interface, network administrators can manually bind a MACaddress and an interface in the table. This can prevent malicious users with counterfeit MACaddress from logging in to the local device through other switches.To discard the frames to the specified destination MAC address, configure blackhole entries.

Pre-configuration TasksBefore configuring the MAC address table based on the VLAN and Layer 2 interface, completethe following tasks:l Creating a VLANl Ensuring that the Layer 2 ports in the MAC address entries are added to the VLANl Ensuring that the mapping between the VE interface and the PVC of the ATM interface is

established if the outbound interface is a VE interfaceNOTE

For the configuration of the mapping between the VE interface and the PVC of the ATM interface, referto the HUAWEI NetEngine80E/40E Router Configuration Guide - WAN Access.

Data PreparationTo configure the MAC address table based on the VLAN and Layer 2 interface, you need thefollowing data.

No. Data1 MAC address2 Port number3 VLAN ID

1.2.2 Configuring MAC Address EntriesTo enhance the security of an interface and to prevent the invalid users from accessing theinterface, the network administrator can manually configure static MAC address entries and bindMAC addresses to the interface, or discard the packets with specified destination MACaddresses. The interface to which the MAC addresses are bound must be a switched interface,



3

and must be added to a specified VLAN, or the interface allows the packets with specified VLANIDs to pass through.

ProcedureStep 1 Run:

system-view

The system view is displayed.Step 2 Run:

mac-address static mac-address interface-type interface-number vlan vlan-id [ ce-vlan ce-vlan]

MAC address entries are added.Note the following:l You can add only unicast MAC addresses rather than multicast MAC addresses and special

MAC addresses to a MAC address table. Special MAC addresses are reserved for specialusage, such as MAC addresses of special packets.

l The interface type can be physical interface such as Ethernet interface and GE interface, orlogical interface such as Eth-Trunk interface and MAC-Tunnel. The interface specified inthe mac-address static command must be a switched interface, serving as an outboundinterface for Layer 2 forwarding.

l The vlan-id must be associated with ports. That is, the VLAN contains the port. Alternatively,this interface allows the VLAN to pass through.

l When ce-vlan is used, it indicates that the interface specified by interface-type interface-number is added to the specified VLAN in VLAN mapping mode. The parameter ce-vlanindicates the exterior VLAN ID in frames received by the port.

l When ce-vlan is not used, it indicates that the interface specified by interface-type interface-number is added to the specified VLAN in port default, trunk, or VLAN stacking mode.

l A maximum of 1024 non-dynamic entries can be added.Step 3 Run:

mac-address blackhole mac-address vlan vlan-id

The blackhole MAC address entry is configured.----End

1.2.3 Configuring MAC Address Entries Based on the Layer 2 VEInterface

If the interface bound to the MAC address of a user device is a Virtual Ethernet (VE) interface,you can configure a MAC address table based on Layer 2 VE interfaces. In this manner, thepackets with specific destination MAC addresses are forwarded by specified interfaces.

ContextNOTE

The ATM interface cannot be configured on the X1 and X2 models of the NE80E/40E.

Do as follows on the router where the VLAN is created:

ProcedureStep 1 Run:

system-view

The system view is displayed.Step 2 Run:

mac-address static mac-address virtual-ethernet interface-number atm interface-number pvc { pvc-name [ vpi | vci ] | vpi | vci } vlan vlan-id

MAC address entries are added. Note the following:l You can add only unicast MAC addresses rather than multicast MAC addresses and special

MAC addresses to a MAC address table. Special MAC addresses are reserved for specialusage, such as MAC addresses of special packets.

l The VE interface must be a switched interface. In addition, the VE interface must beassociated with the VLAN specified by vlan-id. That is, the VLAN contains this VE interface;or this VE interface is added to VLAN by default.
