MAC address table commands The MAC address table contains only Layer 2 Ethernet interfaces. This document covers the configuration of unicast MAC address entries, including static, dynamic, and blackhole MAC address entries. For more information about configuring static multicast MAC address entries, see IP Multicast Configuration Guide. MAC address table commands are supported only on Layer 2 interface cards on MSR routers. display mac-address Use display mac-address to display MAC address entries.
MAC Address VLAN ID State Port Aging 0033-0033-0033 100 Blackhole N/A N 0000-0000-0002 100 Static GE2/1/3 N 00e0-fc00-5829 100 Learned GE2/1/4 Y # Display the total number of MAC address entries. display mac-address count 1 mac address(es) found. Table 1 Command output Field Description VLAN ID ID of the VLAN to which the outgoing interface of the MAC address entry belongs. MAC address entry state: State • Static—Static MAC address entry.
Related commands mac-address timer display mac-address mac-learning Use display mac-address mac-learning to display the global MAC address learning status and the MAC learning status of interfaces. Syntax display mac-address mac-learning [ interface interface-type interface-number ] Views Any view Predefined user roles network-admin network-operator Parameters interface interface-type interface-number: Specifies an interface by its type and number.
mac-address (interface view) Use mac-address to add or modify a MAC address entry on an interface. Use undo mac-address to delete a MAC address entry on an interface. Syntax mac-address { dynamic | static } mac-address vlan vlan-id undo mac-address { dynamic | static } mac-address vlan vlan-id Default An interface is not configured with any MAC address entries. Views Layer 2 Ethernet interface Predefined user roles network-admin Parameters dynamic: Specifies dynamic MAC address entries.
mac-address (system view) Use mac-address to add or modify a MAC address entry. Use undo mac-address to delete one or all MAC address entries.
To drop frames with the specified destination MAC addresses, you can configure blackhole MAC address entries. A static or blackhole MAC address entry can overwrite a dynamic MAC address entry, but not vice versa. If you execute the undo mac-address command without specifying any parameters, this command deletes all unicast MAC address entries and static multicast MAC address entries.
• Because disabling MAC address learning can result in broadcast storms, enable broadcast storm suppression after you disable MAC address learning on an interface. For more information about broadcast storm suppression, see Interface Configuration Guide. Examples # Disable MAC address learning on interface GigabitEthernet 2/1/1.
Examples # Set the aging time to 500 seconds for dynamic MAC address entries.
Ethernet link aggregation commands In this chapter, "MSR2000" refers to MSR2003. "MSR3000" collectively refers to MSR3012, MSR3024, MSR3044, MSR3064. "MSR4000" collectively refers to MSR4060 and MSR4080. bandwidth Use bandwidth to configure the expected bandwidth for an interface. Use undo bandwidth to restore the default. Syntax bandwidth bandwidth-value undo bandwidth Default The expected bandwidth (in kbps) is the interface baud rate divided by 1000.
Predefined user roles network-admin Usage guidelines CAUTION: The default command might interrupt ongoing network services. Make sure you are fully aware of the impacts of this command when you execute it on a live network. This command might fail to restore the default settings for some commands for reasons such as command dependencies and system restrictions.
display interface Use display interface to display aggregate interface information. Syntax display interface [ route-aggregation [ interface-number ] ] [ brief [ description | down ] ] Views Any view Predefined user roles network-admin network-operator Parameters route-aggregation: Displays information about Layer 3 aggregate interfaces. interface-number: Specifies an existing aggregate interface number.
Last clearing of counters: Never Last 300 seconds input rate: 0 bytes/sec, 0 bits/sec, 0 packets/sec Last 300 seconds output rate: 0 bytes/sec, 0 bits/sec, 0 packets/sec 0 packets input, 0 bytes, 0 drops 0 packets output, 0 bytes, 0 drops # Display brief information about Layer 3 aggregate interface Route-Aggregation 1.
Field Description IP packet processing. Disabled indicates that IP packets cannot be processed. Internet protocol processing For an interface configured with an IP address, this field changes to Internet Address is. Brief information on interface(s) under route mode Brief information about Layer 3 interfaces.

Syntax display lacp system-id Views Any view Predefined user roles network-admin network-operator Usage guidelines You can use the lacp system-priority command to change the LACP priority of the local system. The LACP priority value is specified in decimal format in the lacp system-priority command. However, it is displayed as a hexadecimal value by the display lacp system-id command. Examples # Display the local system ID.
Usage guidelines To display the global link-aggregation load sharing criteria, execute the command without the interface keyword. To display all group-specific load sharing criteria, execute the command with the interface keyword, but do not specify a particular interface. To display the load sharing criteria of a particular aggregation group, execute the command with the aggregate interface specified.
Table 5 Command output Field Description Global link-aggregation load sharing criteria. Link-Aggregation Load-Sharing Mode • By default, the link-aggregation load sharing criteria for Layer 3 traffic, Layer 4 traffic, and MPLS traffic are displayed. • If you have configured the global link-aggregation load sharing criteria, the configured ones are displayed. Link-aggregation load sharing criteria of the aggregation group corresponding to aggregate interface Route-Aggregation 10.
Flags: A -- LACP_Activity, B -- LACP_Timeout, C -- Aggregation, D -- Synchronization, E -- Collecting, F -- Distributing, G -- Defaulted, H -- Expired GigabitEthernet2/1/1: Aggregate Interface: Route-Aggregation1 Port Number: 1 Port Priority: 32768 Oper-Key: 1 # Display detailed link aggregation information for GigabitEthernet 2/1/2, which is a member port of a dynamic aggregation group.
Table 6 Command output Field Description LACP state flags. This field is one byte long, represented by ABCDEFGH from the least significant bit to the most significant bit. The letter is present when its bit is 1 and absent when its bit is 0. • A—Indicates whether LACP is enabled. 1 indicates enabled, and 0 indicates disabled. • B—Indicates the LACP short or long timeout. 1 indicates short timeout, and 0 indicates long timeout.
Usage guidelines Information about the remote system for a static link aggregation group is displayed as none. This is because static link aggregation groups are unaware of information about the peer groups. Examples # Display the summary information for all aggregation groups.
Syntax display link-aggregation verbose [ route-aggregation [ interface-number ] ] Views Any view Predefined user roles network-admin network-operator Parameters route-aggregation: Displays detailed information about the Layer 3 aggregation groups that correspond to Layer 3 aggregate interfaces. interface-number: Specifies an existing aggregate interface by its number in the range of 1 to 8.
# Display detailed information about the aggregation group that corresponds to Layer 3 aggregate interface Route-Aggregation 20, which is a static aggregation group.

Status—Selected or Unselected state of the port. Priority—Port priority. Oper-Key—Operational key. Flag—LACP state flag. NOTE: For static aggregation groups, only local information (without the Flag field) is displayed. Information about the remote end: Remote • • • • • • Actor—Port type and number of the local end.
Usage guidelines When you create a Layer 3 aggregate interface, the system automatically creates a Layer 3 aggregation group with the same number. The Layer 3 aggregation group operates in static aggregation mode by default. Removing the Layer 3 aggregate interface also removes the Layer 3 aggregation group. At the same time, the member ports of the aggregation group, if any, leave the aggregation group.
lacp period short Use lacp period short to set the LACP timeout interval on a port to the short timeout interval (3 seconds), and enable the peer end to send LACPDUs quickly. Use undo lacp period to restore the default setting. Syntax lacp period short undo lacp period Default The LACP timeout interval is the long timeout interval (90 seconds).
Related commands link-aggregation port-priority link-aggregation global load-sharing mode Use link-aggregation global load-sharing mode to configure the global link-aggregation load sharing criteria. Use undo link-aggregation global load-sharing mode to restore the default setting.
Default Link-aggregation traffic redirection is disabled. Views System view Predefined user roles network-admin Usage guidelines When you shut down a Selected port in an aggregation group, this feature redirects traffic to other Selected ports. Zero packet loss is guaranteed for known unicast traffic, but not for unknown unicast traffic. (MSR2000/MSR3000) When you restart a card that contains Selected ports, this feature redirects traffic to other cards.
Usage guidelines The load sharing criteria that you configure overwrites the previous criteria. If unsupported load sharing criteria are configured, an error prompt appears. Examples # Configure the destination IP address as the load sharing criterion that is specific to the link aggregation group of aggregate interface Route-Aggregation 1.
Default The port priority of an interface is 32768. Views Layer 3 Ethernet interface view Predefined user roles network-admin Parameters port-priority: Specifies the port priority in the range of 0 to 65535. The smaller the value, the higher the port priority. Examples # Set the port priority of Layer 3 Ethernet interface GigabitEthernet 2/1/2 to 64.
The maximum number of Selected ports allowed in an aggregation group is limited by one of the following, whichever value is smaller: • The configured maximum number. • Hardware capability. You can configure backup between two ports by performing the following tasks: • Assign two ports to an aggregation group. • Configure the maximum number of Selected ports allowed in the aggregation group as one.
Examples # Configure the minimum number of Selected ports as 3 in the aggregation group that corresponds to Layer 3 aggregate interface Route-Aggregation 1. system-view [Sysname] interface route-aggregation 1 [Sysname-Route-Aggregation1] link-aggregation selected-port minimum 3 Related commands link-aggregation selected-port maximum mtu Use mtu to set the MTU of a Layer 3 aggregate interface or subinterface. Use undo mtu to restore the default setting.
Default An Ethernet interface does not belong to any aggregation group. Views Layer 3 Ethernet interface view Predefined user roles network-admin Parameters number: Specifies the number of the aggregate interface that corresponds to an aggregation group. The value range is 1 to 8. Usage guidelines An Ethernet interface can belong to only one aggregation group.

They are in the format of instance-list = { instance-id [ to instance-id ] }&<1-10>, where &<1-10> indicates that you can specify up to 10 instances or instance ranges. The value range for the instance-id argument is 0 to 4094, and the value 0 represents the CIST.
stp edged-port Use stp edged-port to configure a port as an edge port. Use undo stp edged-port to configure a port as a non-edge port. Syntax stp edged-port undo stp edged-port Default All ports are non-edge ports. Views Layer 2 Ethernet interface view Predefined user roles network-admin Usage guidelines If a port directly connects to a user terminal rather than to another device or a shared LAN segment, this port is regarded as an edge port.
undo stp enable Default The spanning tree feature is enabled on all ports. Views Layer 2 Ethernet interface view Predefined user roles network-admin Usage guidelines When you enable the spanning tree feature, the device operates in STP, RSTP, PVST, or MSTP mode, depending on the spanning tree mode setting. When you enable the spanning tree feature, the device dynamically maintains the spanning tree status of VLANs, based on received configuration BPDUs.
Usage guidelines Enable this feature both globally and on ports connected to other vendors' devices. To minimize impact, enable the feature on all associated ports before you enable it globally. Examples # Enable Digest Snooping on GigabitEthernet 2/1/1 and then globally.
stp global mcheck Use stp global mcheck to perform the mCheck operation globally. Syntax stp global mcheck Views System view Predefined user roles network-admin Usage guidelines If a port on a device that is running MSTP, RSTP, or PVST connects to an STP device, the port automatically transits to the STP mode when the port receives STP BPDUs.
Usage guidelines On a port, the loop guard function is mutually exclusive with the root guard function or the edge port setting. When the setting is configured in Layer 2 Ethernet interface view, it takes effect on only the interface. Examples # Enable the loop guard function on GigabitEthernet 2/1/1.
Views Layer 2 Ethernet interface view Predefined user roles network-admin Usage guidelines If a port on a device that is running MSTP, RSTP, or PVST connects to an STP device, the port automatically transits to the STP mode when the port receives STP BPDUs. If the peer STP device is shut down or removed and the local device cannot detect the change, the local device cannot automatically transit back to the original mode.
Parameters mstp: Configures the spanning tree device to operate in MSTP mode. pvst: Configures the spanning tree device to operate in PVST mode. rstp: Configures the spanning tree device to operate in RSTP mode. stp: Configures the spanning tree device to operate in STP mode.
