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

System view

Predefined user roles

network-admin

Parameters

interface-number: Specifies a Layer 3 aggregate interface number. The value range for this argument is 1 to 8.

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 subnumber 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. 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.

Usage guidelines

The default port selection action applies to dynamic aggregation groups.

This action automatically chooses the port with the lowest ID from among all up member ports as a Selected port if none of them has received LACPDUs before the LACP timeout interval expires.

After this action is disabled, a dynamic aggregation group will not have any Selected ports to forward traffic if it has not received LACPDUs before the LACP timeout interval expires.

Usage guidelines

To establish a dynamic aggregation between two remote CEs in an L2VPN network, use transparent LACPDU transmission on the PEs to which the CEs are attached.

On the PEs, enable transparent LACPDU transmission on the interfaces that transmit traffic between CEs and PEs and between PEs.

Do not use an interface for dynamic link aggregation if you enable transparent LACPDU transmission on that interface. With transparent LACPDU transmission enabled, an interface cannot be selected for aggregation.

Examples

# Enable transparent LACPDU transmission on GigabitEthernet 1/0/12.

<Sysname> system

[Sysname-GigabitEthernet1/0/12] lacp transparent enable

link-aggregation bfd

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

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

Syntax

link-aggregation bfd ipv4 source ipv4-address destination ipv4-address

undo link-aggregation bfd

Default

BFD is disabled for an aggregation group.

Views

Layer 3 aggregate interface view

Predefined user roles

network-admin

Parameters

ipv4: Specifies IPv4 BFD.

source: Specifies the source IP address of BFD sessions.

destination: Specifies the destination IP address of BFD sessions.

ipv4-address: Specifies an IPv4 address. The 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 you configure BFD multiple times for an aggregate interface, the most recent configuration takes effect.

Examples

# Enable IPv4 BFD for Layer 3 aggregation group 1, and specify the source and destination IPv4 addresses as 1.1.1.1 and 2.2.2.2 for BFD sessions.

<Sysname> system-view

[Sysname] interface route-aggregation 1

link-aggregation bfd-compatible enable

Use link-aggregation bfd-compatible enable to enable BFD compatible mode on an aggregate interface.

Use undo link-aggregation bfd-compatible enable to disable BFD compatible mode on an aggregate interface.

Syntax

link-aggregation bfd-compatible enable

undo link-aggregation bfd-compatible enable

Default

BFD compatible mode is disabled on aggregate interfaces.

Views

Layer 3 aggregate interface view

Predefined user roles

network-admin

Usage guidelines

BFD compatible mode enables BFD to operate correctly on an aggregate link whose remote end is a third-party device that implements BFD differently from the device.

With BFD compatible mode enabled, all member ports in an aggregation group establish BFD sessions with their peer ports. The BFD sessions are not deleted or re-established when the aggregation states of the member ports change.

Examples

# Enable BFD compatible mode on Route-Aggregation 1.

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 one of the following events occurs:

· The port is shut down by using the shutdown command.

· The slot that hosts the port reboots, but the aggregation group contains Selected ports on other slots.

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

link-aggregation mode

Parameters

dynamic: Specifies dynamic mode and enables LACP.

static: Specifies static mode.

backup: Specifies static 1+1 backup mode. If you do not specify this keyword, 1+1 backup is not enabled. Only Layer 3 aggregate interfaces support this keyword.

link-aggregation primary-port

Use link-aggregation primary-port to assign the primary role to a member port in a 1+1 backup aggregation group.

Use undo link-aggregation primary-port to restore the default.

Syntax

link-aggregation primary-port

undo link-aggregation primary-port

Default

A member port is not assigned the primary role in a 1+1 backup aggregation group.

Views

Layer 3 Ethernet interface view

Predefined user roles

network-admin

Usage guidelines

In a 1+1 backup aggregation group, the primary member port is placed in Selected state to forward all traffic, and the secondary member port is placed in Unselected state as a standby. You can specify a primary member port with this command or let the system to select a primary member port. If you specify a primary member port for a 1+1 backup aggregation group, the aggregation group can revert to the primary member port when that port recovers from failure. As a best practice, use this command to manually specify a primary member port.

If you do not specify a primary member port for an aggregation group, the system acts as follows:

· Assigns the primary role to the reference port If the member ports join the aggregation group simultaneously.

· Assigns the primary role to the member port that first becomes Selected if the member ports join the aggregation group successively.

This command is not available on a port that is not an aggregation group member or is in an aggregation group not operating in 1+1 backup mode.

A 1+1 backup aggregation group can have only one primary member port.

Examples

# Assign the primary role to GigabitEthernet 1/0/12.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/12

link-aggregation reversion delay

Use link-aggregation reversion delay to set the reversion delay for a 1+1 backup aggregation group.

Use undo link-aggregation reversion delay to restore the default.

Syntax

undo link-aggregation reversion delay

Default

A 1+1 backup aggregation group reverts to the primary member port immediately after that port recovers from failure.

Views

Layer 3 aggregate interface view

Predefined user roles

network-admin

Parameters

time-value: Sets a reversion delay in the range of 1 to 65535 seconds.

Usage guidelines

The reversion delay is the time a 1+1 backup aggregation group must wait before reverting to the primary member port after that port recovers from failure. This timer prevents link flapping from causing frequent primary/secondary member port switchovers.

For this command to take effect on an aggregation group, first configure the aggregation group to operate in 1+1 backup mode and manually specify its primary member port.

Examples

# Set the reversion delay to 5 seconds on Route-Aggregation 1.

<Sysname> system-view

[Sysname] interface route-aggregation 1

[Sysname-Route-Aggregation1] link-aggregation reversion delay 5

Default

In a 1+1 backup aggregation group, the secondary member port is in Unselected state.

Views

Layer 3 aggregate interface view

Predefined user roles

network-admin

Usage guidelines

If the peer for a 1+1 backup aggregation group is unaware of the member port roles, it might send traffic to the secondary member port, and traffic loss occurs consequently. To prevent traffic loss, configure the aggregation group to place its secondary member port in down state. This allows the peer and local ends to use only up ports to transmit traffic.

For this command to take effect on an aggregation group, first configure the aggregation group to operate in 1+1 backup mode.

Examples

# Configure Route-Aggregation 1 to place its secondary member port in down state.

Views

Layer 3 aggregate interface view

Predefined user roles

network-admin

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.

lacp-sync: Synchronizes the maximum number of Selected ports through LACPDUs. If you do not specify this keyword, the aggregate interface does not synchronize the maximum number of Selected ports with the peer.

Usage guidelines

Executing this command might cause some of the Selected ports in an aggregation group to become Unselected ports.

For a static aggregate link, you must set the maximum number of Selected ports to the same value at its two ends.

For a dynamic aggregate link, you must set the maximum number of Selected ports to the same value at its two ends if you do not specify the lacp-sync keyword. If you specify this keyword, the two ends of the aggregate link compare their maximum Selected port number settings and use the smaller value.

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.

Examples

# Set the maximum number of Selected ports to 5 for Layer 3 aggregation group 1.

<Sysname> system-view

[Sysname] interface route-aggregation 1

[Sysname-Route-Aggregation1] link-aggregation selected-port maximum 5

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.

Parameters

min-number: Specifies the minimum number of Selected ports in an aggregation group required to bring up the aggregate interface. The value range for this argument is 1 to 8.

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.

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

Examples

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

Parameters

number: Specifies the minimum percentage of Selected ports. The value range for this argument is 1 to 100.

Usage guidelines

CAUTION:

After you execute this command, aggregate interface flapping might occur when ports join or leave an aggregation group. Make sure you are fully aware of the impacts of this command when you execute it on a live network.

You must set the same minimum percentage of Selected ports at the two ends of an aggregate link.

The minimum number of Selected ports in an aggregation group equals the higher one of the following values:

· The number of member ports in the aggregation group multiplied by the minimum percentage of Selected ports.

· The limit set by using the link-aggregation selected-port minimum command.

The system calculates the minimum percentage of Selected ports based on the total number of member ports in an aggregation group, including the member ports on an absent card. To view the total number of member ports in an aggregation group, execute the display link-aggregation verbose all-configuration command.

For the device to calculate the minimum number of Selected ports correctly, save the running configuration and reboot the device after you execute the link-aggregation selected-port minimum percentage command.

Examples

# Set the minimum percentage of Selected ports to 50% for Layer 3 aggregate interface Route-Aggregation 1.

Usage guidelines

CAUTION:

This command might cause traffic loss. Make sure you are fully aware of the impacts of this command when you execute it on a live network.

Use this command to switch member port roles for a 1+1 backup aggregation group whose primary member port is set by the system when the state of peer ports changes.

If the link-aggregation secondary-down command has been executed for the aggregation group, the link-aggregation switchover command brings up the down secondary member port for it to take over the primary role.

Before you execute the link-aggregation switchover command for a 1+1 backup aggregation group, verify that the following requirements are met:

· The aggregation group contains one Selected port and one Unselected port.

· The primary member port is set by the system.

· The secondary member port can become Selected.

Examples

# Perform a primary/secondary member port switchover in the aggregation group of Route-Aggregation 1.

Predefined user roles

network-admin

Parameters

down: Suppresses link-down events.

up: Suppresses link-up events.

msec: Sets the physical state change suppression interval in milliseconds. If you do not specify this keyword, the suppression interval is in seconds.

delay-time: Sets the physical state change suppression interval. To report a physical state change immediately to the CPU, set the interval to 0.

· If you do not specify the msec keyword, the value range is 0 to 600 seconds.

· If you specify the msec keyword, the value range is 0 to 10000 milliseconds, and the value must be a multiple of 10.

Usage guidelines

You can configure this feature to suppress link-down events, link-up events, or both. If an event of the specified type still exists when the suppression interval expires, the system reports the event.

On an interface, you can configure different suppression intervals for link-up and link-down events. If you execute the link-delay command multiple times for an event type, the most recent configuration takes effect on that event type.

When you configure suppression interval settings on an aggregate interface, make sure its peer interface is also an aggregate interface in the same aggregation mode. In addition, the suppression interval settings must be the same between the peer aggregate interfaces.

As a best practice, use the default setting in an S-MLAG environment.

Examples

# Set the link-down event suppression interval to 500 milliseconds on Route-Aggregation 1.
