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.

Access controller modules	EWPXM2WCMD0F LSQM1WCMX20 LSUM1WCMX20RT	1 to 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.

· 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

Related commands

link-aggregation selected-port minimum

Use link-aggregation selected-port minimum to set the minimum number of Selected ports in an aggregation group.

Use undo link-aggregation selected-port minimum to restore the default.

Syntax

undo link-aggregation selected-port minimum

Default

The minimum number of Selected ports in an aggregation group is not specified.

Usage guidelines

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

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

Examples

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

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

reset lacp statistics

Use reset lacp statistics to clear LACP statistics for the specified link aggregation member ports.

interface interface-list: Specifies a list of link aggregation member ports, in the format interface-type interface-number [ to interface-type interface-number ]. The interface-type interface-number argument specifies an interface by its type and number. If you do not specify any member ports, the command clears LACP statistics for all member ports.

Examples

# Clear LACP statistics for all link aggregation member ports.
