Parameters

interface-number: Specifies a Layer 2 aggregate interface number. The value range for the interface-number argument is 1 to 8.

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.

interface route-aggregation

Use interface route-aggregation to create a Layer 3 aggregate interface or subinterface and enter its view, or enter the view of an existing Layer 3 aggregate interface or subinterface.

Use undo interface route-aggregation to delete a Layer 3 aggregate interface or subinterface.

Syntax

interface route-aggregation { interface-number | interface-number.subnumber }

undo interface route-aggregation { interface-number | interface-number.subnumber }

Default

No Layer 3 aggregate interfaces or subinterfaces exist.

Views

network-admin

Parameters

interface-number: Specifies a Layer 3 aggregate interface number. The value range for the interface-number argument is 1 to 32.

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 and is separated from the main interface number by a dot (.). The value range for the interface-number argument is 1 to 4094.

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.

Use link-aggregation bfd ipv4 to enable BFD for an aggregation group.

Use undo link-aggregation bfd to disable BFD for an aggregation group.

Syntax

undo link-aggregation bfd

Default

BFD is disabled for an aggregation group.

Views

Layer 3 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 established by the member ports in its aggregation group. BFD on a link aggregation supports only control packet mode for session establishment and maintenance. The two ends of an established BFD session can only operate in Asynchronous mode. For more information about BFD, see High Availability Configuration Guide.

As a best practice, do not configure BFD for any protocols 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.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

Predefined user roles

network-admin

Parameters

vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN ID or a range of VLAN IDs in the form of vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to 4094. The value for the vlan-id2 argument must be equal to or greater than the value for the vlan-id1 argument.

Usage guidelines

This command takes effect only when the link type of the Layer 2 aggregate interface is hybrid or trunk.

With this command configured, a Layer 2 aggregate interface ignores the permitted VLAN and VLAN tagging mode configuration of the specified VLANs when choosing Selected ports.

Examples

# Configure Layer 2 aggregate interface bridge-aggregation 1 to ignore VLAN 50.

Views

Layer 3 aggregate interface view

Predefined user roles

network-admin

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.

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.

Examples

# Enable link-aggregation traffic redirection.

<Sysname> system-view

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

link-aggregation load-sharing mode

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.

For an aggregation group, the maximum number of Selected ports must be equal to or higher than the minimum number of Selected ports.

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.

Predefined user roles

network-admin

Parameters

slot slot-number: Specifies a card by its slot number. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. (In IRF mode.)

Usage guidelines

Specify a traffic processing slot for all traffic on a Layer 3 aggregate interface to be processed on the same slot. If the aggregate interface contains subinterfaces, traffic on the subinterfaces is also processed on the specified slot.

For high availability, you can specify one primary and one backup traffic processing slot by using the service command and the service standby command, respectively.

To avoid processing slot switchover, specify the primary slot before specifying the backup slot. If you specify the backup slot before specifying the primary slot, traffic is switched over to the primary slot immediately after you specify the primary slot.

If you specify both primary and backup slots for an interface, traffic on that interface is processed as follows:

· The backup slot takes over when the primary slot becomes unavailable. The backup slot continues to process traffic for the interface after the primary slot becomes available again. The switchover will not occur until the backup slot becomes unavailable.

· When no specified traffic processing slots are available, the traffic is processed on the slot at which it arrives. Then, the processing slot that first becomes available again takes over.

If you do not specify a primary or a backup traffic processing slot for an interface, traffic on that interface is processed on the slot at which the traffic arrives.
