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

Parameters
interface-number: Specifies a Layer 3 aggregate interface number. The value range for the interface-number argument is 1 to 1024.
interface-number.subnumber: Specifies a subinterface of a Layer 3 aggregate interface. The interface-number argument specifies the main interface number. The subnumber argument specifies the subinterface number in the range of 1 to 4096 and is separated from the main interface number by a dot (.).
Usage guidelines
When you create a Layer 3 aggregate interface, the system automatically creates a Layer 3 aggregation group with the same number. The Layer 3 aggregation group operates in static aggregation mode by default.
Deleting a Layer 3 aggregate interface also deletes the Layer 3 aggregation group and all its aggregate subinterfaces. At the same time, the member ports of the aggregation group, if any, leave the aggregation group.
Deleting a Layer 3 aggregate subinterface does not affect the state of the main interface and the corresponding aggregation group.

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 consistent 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 other protocols 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.
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 aggregate interfaces. 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

Parameters
max-number: Specifies the maximum number of Selected ports allowed in an aggregation group. The value range for this argument is 1 to 32.
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.
