Ethernet link aggregation commands

bandwidth

Use bandwidth to set 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.

Views

Layer 2 aggregate interface view

Predefined user roles

network-admin

Parameters

bandwidth-value: Specifies the expected bandwidth in the range of 1 to 400000000 kbps.

Usage guidelines

The expected bandwidth is an informational parameter used only by higher-layer protocols for calculation. You cannot adjust the actual bandwidth of an interface by using this command.

Examples

# Set the expected bandwidth to 10000 kbps for Layer 2 aggregate interface Bridge-Aggregation 1.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

[Sysname-Bridge-Aggregation1] bandwidth 10000

default

Use default to restore the default settings for an aggregate interface.

Usage guidelines

CAUTION

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. Use the display this command in interface view to identify these commands, and then use their undo forms or follow the command reference to restore their default settings. If your restoration attempt still fails, follow the error message instructions to resolve the problem.

Examples

# Restore the default settings for Layer 2 aggregate interface 1.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

[Sysname-Bridge-Aggregation1] default

description

Use description to set a description for an interface.

Use undo description to restore the default.

Syntax

description text

undo description

Default

The description of an interface is interface-name Interface. For example, the default description of Bridge-Aggregation 1 is Bridge-Aggregation1 Interface.

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]

lacp mode

Use lacp mode passive to configure LACP to operate in passive mode on a port.

Use undo lacp mode to restore the default.

Syntax

lacp mode passive

undo lacp mode

Default

LACP is operating in active mode on a port.

Views

Usage guidelines

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.

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

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 set the short LACP timeout interval (3 seconds) on an interface.

Use undo lacp period to restore the default.

Syntax

lacp period short

undo lacp period

Default

The LACP timeout interval is the long timeout interval (90 seconds).

Usage guidelines

When you restart an IRF member device that contains Selected ports, this feature redirects traffic of the IRF member device to other IRF member devices. Zero packet loss is guaranteed for known unicast traffic, but not for unknown unicast traffic.

Link-aggregation traffic redirection 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.

Examples

# Enable link-aggregation traffic redirection.

<Sysname> system-view

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

link-aggregation load-sharing mode

Use link-aggregation load-sharing mode to set the link-aggregation load sharing mode.

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.

·     Hardware limitation.

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

·     Assign two ports to an aggregation group.

·     Configure 1 as the maximum number of Selected ports allowed in 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

If you do not specify any parameters, the command clears statistics for all interfaces in the system.

If you specify only the bridge-aggregation keyword, the command clears statistics for all Layer 2 aggregate interfaces.

If you specify the bridge-aggregation interface-number option, the command clears statistics for the specified aggregate interface.

The bridge-aggregation keyword is available only when Layer 2 aggregate interfaces exist on the device.

Examples

# Clear statistics for Layer 2 aggregate interface Bridge-Aggregation 1.

<Sysname> reset counters interface bridge-aggregation 1
