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

System view

Predefined user roles

network-admin

Parameters

interface-number: Specifies a Layer 2 aggregate interface number. The value for the interface-number argument is fixed at 1.

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

Usage guidelines

This feature redirects traffic on a Selected port to the remaining available Selected ports of an aggregation group if the port is shut down by using the shutdown command.

 

 

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.

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

Examples

# Enable link-aggregation traffic redirection.

<Sysname> system-view

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

Parameters

max-number: Specifies the maximum number of Selected ports allowed in an aggregation group. Valid values for this argument are 1 and 2.

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 2 for Layer 2 aggregation group 1.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

[Sysname-Bridge-Aggregation1] link-aggregation selected-port maximum 2
