Parameters

interface-number: Specifies a Layer 2 aggregate interface number. The value range for the interface-number argument is 1 to 1024.

Usage guidelines

When you create a Layer 2 aggregate interface, the system automatically creates a Layer 2 aggregation group with the same number. The aggregation group operates in static aggregation mode by default.

Deleting a Layer 2 aggregate interface also deletes the Layer 2 aggregation group. At the same time, the member ports of the aggregation group, if any, leave the aggregation group.

Examples

# Create Layer 2 aggregate interface Bridge-Aggregation 1, and enter its view.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

[Sysname-Bridge-Aggregation1]

jumboframe enable

Use jumboframe enable to allow the jumbo frames on an interface to pass through.

Use undo jumboframe enable to deny jumbo frames on an interface.

Use undo jumboframe enable size to restore the default.

Syntax

The default port selection action applies to dynamic aggregation groups.

This action automatically chooses the port with the lowest ID from among all up member ports as a Selected port if none of them has received LACPDUs before the LACP timeout interval expires.

After this action is disabled, a dynamic aggregation group will not have any Selected ports to forward traffic if it has not received LACPDUs before the LACP timeout interval expires.

Examples

# Disable the default port selection action.

<Sysname> system-view

[Sysname] lacp default-selected-port disable

lacp edge-port

Use lacp edge-port to configure an aggregate interface as an edge aggregate interface.

Use undo lacp edge-port to restore the default.

Syntax

lacp edge-port

undo lacp edge-port

Default

An aggregate interface does not operate as an edge aggregate interface.

Usage guidelines

Use this command on the aggregate interface that connects the device to a server if dynamic link aggregation is configured only on the device. This feature improves link reliability by enabling all member ports of the aggregation group to forward packets.

This command takes effect only on an aggregate interface corresponding to a dynamic aggregation group.

Link-aggregation traffic redirection cannot operate correctly on an edge aggregate interface.

Usage guidelines

This command takes effect only on member ports of dynamic aggregation groups.

When LACP is operating in passive mode on a local member port and its peer port, both ports cannot send LACPDUs. When LACP is operating in active mode on either end of a link, both ports can send LACPDUs.

Examples

# Configure LACP to operate in passive mode on GigabitEthernet 1/0/1.

Usage guidelines

CAUTION

CAUTION:

Changing reference port selection criteria might cause transient traffic interruption. When you use this command, make sure you understand its impact on your network.

 

This command enables a dynamic aggregation group to select a high-speed member port as the reference port.

You must execute this command at both ends of the aggregate link so the peer aggregation systems use the same criteria for reference port selection.

As a best practice, shut down the peer aggregate interfaces before you execute this command and bring up the interfaces after this command is executed on both of them.

This command takes effect only on dynamic aggregate interfaces. On a static aggregate interface, you can execute this command, but the setting cannot take effect.

Examples

# Specify port speed as the prioritized criterion for reference port selection on Layer 2 dynamic aggregate interface Bridge-Aggregation 1.

Predefined user roles

network-admin

Parameters

mac-address: Specifies a MAC address in the format of H-H-H. The MAC address cannot be an all-zero, all-F, or multicast MAC address.

Usage guidelines

All S-MLAG devices must use the same LACP system MAC address.

The LACP system MAC address configured by using this command takes effect only on aggregate interfaces in S-MLAG groups. Aggregate interfaces not in S-MLAG groups do not use the configured LACP system MAC address to send LACPDUs. To identify the LACP system MAC address used by a link aggregation group, examine the System ID field in the output from the display link-aggregation verbose command.

Examples

# Set the LACP system MAC address to 0001-0001-0001.

<Sysname> system-view

Parameters

number: Specifies a number in the range of 1 to 3.

Usage guidelines

You must assign a unique LACP system number to each S-MLAG device.

The LACP system number configured by using this command takes effect only on aggregate interfaces in S-MLAG groups. Aggregate interfaces not in S-MLAG groups do not use the configured LACP system number in LACPDUs. To view the LACP system number in LACPDUs, examine the Index field in the output from the display link-aggregation verbose command.

link-aggregation bfd ipv4

Use link-aggregation bfd ipv4 to enable BFD for an aggregation group.

Use undo link-aggregation bfd to disable BFD for an aggregation group.

Syntax

link-aggregation bfd ipv4 source ip-address destination ip-address

undo link-aggregation bfd

Default

BFD is disabled for an aggregation group.

Views

Layer 2 aggregate interface view

Predefined user roles

network-admin

Parameters

source ip-address: Specifies the unicast source IP address of BFD sessions. The source IP address cannot be 0.0.0.0.

destination ip-address: Specifies the unicast destination IP address of BFD sessions. The destination IP address cannot be 0.0.0.0.

Usage guidelines

Make sure the source and destination IP addresses are reversed between the two ends of an aggregate link. For example, if you execute link-aggregation bfd ipv4 source 1.1.1.1 destination 2.2.2.2 at the local end, execute link-aggregation bfd ipv4 source 2.2.2.2 destination 1.1.1.1 at the peer end. The source and destination IP addresses cannot be the same.

The BFD parameters configured on an aggregate interface take effect on all BFD sessions established by the member ports in its aggregation group. BFD on an aggregate link supports only control packet mode for session establishment and maintenance. The two ends of an established BFD session can only operate in Asynchronous mode. For more information about BFD, see High Availability Configuration Guide.

As a best practice, do not configure BFD for any protocols on a BFD-enabled aggregate interface.

Make sure the number of member ports in the BFD-enabled aggregation group is less than or identical to the number of BFD sessions supported by the device. If the aggregation group contains more member ports than the supported sessions, some Selected ports might change to the Unselected state.

If the number of BFD sessions differs between the two ends of an aggregate link, check their settings for inconsistency in the maximum number of Selected ports. You must make sure the two ends have the same setting for the maximum number of Selected ports.

Examples

# Enable BFD for Layer 2 aggregation group 1, and specify the source and destination IP addresses as 1.1.1.1 and 2.2.2.2 for BFD sessions.

Views

System view

Layer 2 aggregate interface view

Predefined user roles

network-admin

Usage guidelines

This feature redirects traffic on a Selected port to the remaining available Selected ports of an aggregation group if one of the following events occurs:

·     The port is shut down by using the shutdown command.

·     The slot that hosts the port reboots, and the aggregation group spans multiple slots.

 

 

NOTE:

The device does not redirect traffic to member ports that become Selected during the traffic redirection process.

 

This feature ensures zero packet loss for known unicast traffic, but does not protect unknown unicast traffic.

This feature applies only to dynamic link aggregation groups.

To prevent traffic interruption, enable link-aggregation traffic redirection on devices at both ends of the aggregate link.

To prevent packet loss that might occur when a slot reboots, do not enable spanning tree together with link-aggregation traffic redirection.

Link-aggregation traffic redirection cannot operate correctly on an edge aggregate interface.

Global link-aggregation traffic redirection settings take effect on all aggregation groups. A link aggregation group preferentially uses the group-specific link-aggregation traffic redirection settings. If group-specific link-aggregation traffic redirection is not configured, the group uses the global link-aggregation traffic redirection settings.

As a best practice, enable link-aggregation traffic redirection on a per-interface basis. If you enable this feature globally, communication with a third-party peer device might be affected if the peer is not compatible with this feature.

Examples

# Enable link-aggregation traffic redirection.

<Sysname> system-view

[Sysname] link-aggregation lacp traffic-redirect-notification enable

link-aggregation load-sharing mode local-first

Predefined user roles

network-admin

Usage guidelines

Use local-first load sharing in a multidevice link aggregation scenario to distribute traffic preferentially across member ports on the ingress card or device. Local-first load sharing takes effect only on known unicast traffic.

If you disable local-first load sharing, packets of an aggregate interface are load shared among all Selected ports on IRF member devices.

Views

Layer 2 aggregate interface view

Predefined user roles

network-admin

Parameters

max-number: Specifies the maximum number of Selected ports allowed in an aggregation group. The value range for this argument is 1 to 8.

Usage guidelines

Executing this command might cause some of the Selected ports in an aggregation group to become Unselected ports.

The maximum number of Selected ports allowed in the aggregation groups must be the same for the local and peer ends.

For an aggregation group, the maximum number of Selected ports must be equal to or higher than the minimum number of Selected ports.

The maximum number of Selected ports allowed in an aggregation group is limited by one of the following values, whichever value is smaller:

·     Maximum number set by using the link-aggregation selected-port maximum command.

·     Maximum number of Selected ports allowed by the link aggregation capability.

You can implement backup between two ports by performing the following tasks:

·     Assigning two ports to an aggregation group.

·     Setting the maximum number of Selected ports to 1 for the aggregation group.

Then, only one Selected port is allowed in the aggregation group at any point in time, while the Unselected port acts as a backup port.

Examples

# Set the maximum number of Selected ports to 5 for Layer 2 aggregation group 1.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

[Sysname-Bridge-Aggregation1] link-aggregation selected-port maximum 5

network-admin

Parameters

min-number: Specifies the minimum number of Selected ports in an aggregation group required to bring up the aggregate interface. The value range for this argument is 1 to 8.

percentage number: Sets the minimum percentage of Selected ports in an aggregation group. The value range for the number argument is 1 to 100.

Usage guidelines

IMPORTANT

IMPORTANT:

After you set the minimum percentage of Selected ports for an aggregation group, aggregate interface flapping might occur when ports join or leave an aggregation group. Make sure you are fully aware of the impacts of this setting when you configure it on a live network.

 

You can set either the minimum number or the minimum percentage of Selected ports for an aggregation group. If you configure both settings on an aggregate interface, the higher Selected port number limit takes effect.

Executing this command might cause all member ports in the aggregation group to become Unselected ports.

You must set the same minimum number or minimum percentage of Selected ports at the two ends of an aggregate link.

For an aggregation group, the minimum number of Selected ports must be equal to or lower than the maximum number of Selected ports.

Examples

# Set the minimum number of Selected ports to 3 for Layer 2 aggregation group 1.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

[Sysname-Bridge-Aggregation1] link-aggregation selected-port minimum 3

undo link-delay { down | up }

Default

Each time the physical link of an aggregate interface goes up or comes down, the system immediately reports the change to the CPU.

Views

Layer 2 aggregate interface view

Predefined user roles

network-admin

Parameters

down: Suppresses the link-down events.

up: Suppresses the link-up events.

msec: Sets the physical state change suppression interval in milliseconds. If you do not specify this keyword, the suppression interval is in seconds.

delay-time: Sets the physical state change suppression interval. To report a physical state change immediately to the CPU, set the interval to 0.

·     If you do not specify the msec keyword, the value range is 0 to 30 seconds.

·     If you specify the msec keyword, the value range is 0 to 10000 milliseconds, and the value must be a multiple of 100.

Usage guidelines

You can configure this feature to suppress link-down events, link-up events, or both. If an event of the specified type still exists when the suppression interval expires, the system reports the event.

On an interface, you can configure different suppression intervals for link-up and link-down events. If you execute the link-delay command multiple times for an event type, the most recent configuration takes effect on that event type.

Do not use this feature in combination with S-MLAG.

When you use this feature on an aggregate interface, make sure its peer is also an aggregate interface. In addition, you must set the physical state change suppression interval to the same value on those aggregate interfaces.

Examples

# Set the link-down event suppression interval to 8 seconds on Bridge-Aggregation 1.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

[Sysname-Bridge-Aggregation1] link-delay down 8

port link-aggregation group

Use port link-aggregation group to assign an interface to an aggregation group.

Use undo port link-aggregation group to remove an interface from the aggregation group to which it belongs.

Syntax

port link-aggregation group { group-id [ force ] | auto [ group-id ] }

undo port link-aggregation group

Default

An interface does not belong to any aggregation group.

Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

Parameters

group-id: Specifies an aggregation group by its aggregate interface number. The value range for the number argument is 1 to 1024.

force: Enables the current interface to synchronize attribute configurations from the aggregate interface. If you do not specify this keyword, the current interface does not synchronize attribute configurations from the aggregate interface when it joins the aggregation group.

auto: Enables automatic assignment.

Usage guidelines

An interface can belong to only one aggregation group.

An interface cannot join an aggregation group if it has different attribute configurations from the aggregate interface. After joining an aggregation group, an interface inherits the attribute configurations on the aggregate interface. You can modify the attribute configurations only on the aggregate interface.

The force keyword takes effect only when you assign the interface to an aggregation group. It cannot be saved in the running configuration or a configuration file.

When you enable automatic assignment, you can specify a preferred aggregation group, which must be in dynamic mode.

The device assigns the interface to the preferred aggregation group as long as the LACPDUs received on the interface match the peer information of the reference port in the group.

If you do not specify a preferred group or if the preferred group match fails, the device attempts to select a matching group from the existing dynamic aggregation groups. If no match is found, the device creates a dynamic aggregation group based on the LACPDUs and assigns the interface to that aggregation group.

As a best practice, do not modify the configuration on an automatically created aggregate interface or its member ports.

Examples

# Assign Layer 2 Ethernet interface GigabitEthernet 1/0/1 to Layer 2 aggregation group 1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1
