interface bridge-aggregation

Use interface bridge-aggregation to create a Layer 2 aggregate interface and enter its view, or enter the view of an existing Layer 2 aggregate interface.

Use undo interface bridge-aggregation to delete a Layer 2 aggregate interface.

Syntax

interface bridge-aggregation interface-number

undo interface bridge-aggregation interface-number

Default

No Layer 2 aggregate interfaces exist.

Views

Predefined user roles

network-admin

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

jumboframe enable [ size ]

undo jumboframe enable [ size ]

Default

An interface allows jumbo frames with a maximum length of 10240 bytes to pass through.

Views

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.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] lacp mode passive

lacp period short

Use lacp period short to enable the short LACP timeout interval (3 seconds) on an interface.

Use undo lacp period to restore the default.

Syntax

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.

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 in the aggregation group. BFD sessions for link aggregation do not support the echo packet mode or the Demand mode. For more information about BFD, see High Availability Configuration Guide.

As a best practice, do not configure a protocol to collaborate with BFD 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.

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 it 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.

# Enable link-aggregation traffic redirection.

<Sysname> system-view

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.

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.

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.

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.

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
