Parameters

interface-number: Specifies a Layer 2 aggregate interface number. The value range for the interface-number argument varies by device model.

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.

Parameters

interface-number: Specifies a Layer 3 aggregate interface number. The value range for the interface-number argument is 1 to 192.

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.

undo link-aggregation bfd [ ipv4 ]

Default

BFD is disabled for an aggregation group.

Views

Predefined user roles

network-admin

mdc-admin

Parameters

ipv4: Specifies IPv4 BFD.

ipv6: Specifies IPv6 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.

ipv6-address: Specifies an IPv6 address. The address cannot be 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.

You can configure both IPv4 and IPv6 BFD. If you configure a BFD type multiple times, the most recent configuration takes effect.

If both IPv4 and IPv6 BFD sessions exist on an aggregate interface, the device places the aggregation member ports in Unselected state when either IPv4 or IPv6 BFD detects a link failure.

Examples

# Enable IPv4 BFD for Layer 2 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 bridge-aggregation 1

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 Bridge-Aggregation 1.

undo link-aggregation global load-sharing mode

Default

By default, the device selects a load sharing mode for packets depending on their packet type, as follows:

· Non-MPLS packets are load shared based on the source and destination IP addresses and source and destination port numbers.

· MPLS packets are load shared based on the source and destination IP addresses, source and destination port numbers, and MPLS labels.

Views

System view

Predefined user roles

Parameters

destination-ip: Load shares traffic based on destination IP addresses.

destination-mac: Load shares traffic based on destination MAC addresses.

destination-port: Load shares traffic based on destination ports.

mpls-label1: Load shares MPLS traffic based on Layer 1 labels.

mpls-label2: Load shares MPLS traffic based on Layer 2 labels.

source-ip: Load shares traffic based on source IP addresses.

source-mac: Load shares traffic based on source MAC addresses.

source-port: Load shares traffic based on source ports.

per-packet: Load shares traffic on a per-packet basis.

Usage guidelines

If you execute this command multiple times, the most recent configuration takes effect.

If an unsupported load sharing mode is set, the device displays an error message.

This command is available only on the default MDC. Non-default MDCs use the global load sharing mode set on the default MDC.

When load sharing traffic, the device always uses the source and destination MAC addresses, IP addresses, or port numbers as hash keys in pairs. If you specify one of the hash keys in a pair, the device will use both hash keys in that pair for load sharing. For example, if you specify the source MAC address, the device uses both source and destination MAC addresses for load sharing.

Examples

# Set the global load sharing mode to load share packets based on destination MAC addresses.

<Sysname> system-view

[Sysname] link-aggregation global load-sharing mode destination-mac

Usage guidelines

IMPORTANT:

Make sure you are fully aware of the impacts of this command when you execute it on a live network.

This command allows ports at a different speed than the reference port to become Selected by ignoring the port speed during operational key calculation.

You must configure the same port speed ignoring setting at the two ends of a static configuration to ensure that the peer ports are placed in the same aggregation state. This requirement does not apply to a dynamic aggregation, on which the two ends negotiate the aggregation state of the peer ports automatically.

undo link-aggregation ignore vlan vlan-id-list

Default

A Layer 2 aggregate interface does not ignore any VLANs.

Views

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.

<Sysname> system-view

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.

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.

Parameters

dynamic: Specifies dynamic mode and enables LACP.

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.

Usage guidelines

Aggregation mode change might cause Selected member ports to become Unselected. When you change the aggregation mode, make sure you understand the impact of the change on services.

You cannot configure an aggregation group to operate in dynamic aggregation mode when the aggregation group uses RPR logical interfaces as member ports.

The following restrictions apply to an aggregation group operating in 1+1 backup mode:

· The aggregation group can contain a maximum of two member ports.

· The maximum and minimum limits on the number of Selected ports in the aggregation group do not take effect.

Predefined user roles

network-admin

mdc-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.

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.

Parameters

max-number: Specifies the maximum number of Selected ports allowed in an aggregation group. The value range for this argument is 1 to 64.

Usage guidelines

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

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

On a dynamic aggregate link, the two ends of the aggregate link compare their maximum Selected port number settings and use the smaller value.

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.

Use link-delay to set the physical state change suppression interval on an aggregate interface.

Use undo link-delay to restore the default.

Syntax

link-delay { down | up } [ msec ] delay-time

undo link-delay { down | up }

Default

Each time the physical link of an aggregate interface goes up or comes down, the system immediately reports the change to the CPU.

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 86400 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 Bridge-Aggregation 1.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

[Sysname-Bridge-Aggregation1] link-delay down msec 500

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

<Sysname> system-view

[Sysname] interface route-aggregation 1

[Sysname-Route-Aggregation1] link-delay down msec 500

mtu

Use mtu to set the MTU for a Layer 3 aggregate interface or subinterface.

Use undo mtu to restore the default.

Syntax

mtu size [ spread ]

undo mtu [ spread ]

Default

The MTU for Layer 3 aggregate interfaces and subinterfaces is 1500 bytes.

Parameters

size: Specifies the MTU in bytes, in the range of 1280 to 9600.

spread: Issues the MTU of the interface to all its subinterfaces. This keyword is available only in Layer 3 aggregate interface view.

Usage guidelines

When you set the MTU of a Layer 3 aggregate interface, you can specify the spread keyword to issue the MTU setting to all its subinterfaces. If you do not specify the spread keyword, the MTU setting takes effect only on the Layer 3 aggregate interface.

On an aggregate subinterface, the MTU set in subinterface view takes precedence over the MTU inherited from the aggregate interface.

Examples

# Set the MTU to 1430 bytes for Layer 3 aggregate interface Route-Aggregation 1.

<Sysname> system-view

[Sysname] interface route-aggregation 1

[Sysname-Route-Aggregation1] mtu 1430

Parameters

bridge-aggregation: Specifies Layer 2 aggregate interfaces.

route-aggregation: Specifies Layer 3 aggregate interfaces.

interface-number: Specifies an aggregate interface number. The value range for the interface-number argument is 1 to 192.

Usage guidelines

Use this command to clear history statistics before you collect traffic statistics for a time period.

If you do not specify an aggregate interface type, the command clears statistics for all interfaces.

If you specify only an aggregate interface type, the command clears statistics for all aggregate interfaces of the specified type.

The route-aggregation keyword is available only when Layer 3 aggregate interfaces exist on the device.

Examples

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

<Sysname> reset counters interface bridge-aggregation 1

# Clear statistics for Layer 3 aggregate interface Route-Aggregation 1.

Usage guidelines

Rate statistics collection for Layer 3 aggregate subinterfaces is resource intensive. When you use this feature on a live network, make sure you fully understand its impact.

This command enables the device to periodically refresh rate statistics for the subinterfaces of a Layer 3 aggregate interface. The rate statistics are available in two statistics polling intervals after you execute this command. To set the statistics polling interval, use the flow-interval command.

Examples

# Enable rate statistics collection for the subinterfaces of Route-Aggregation 1.

<Sysname> system-view

[Sysname] interface route-aggregation 1

[Sysname-Route-Aggregation1] sub-interface rate-statistic

This configuration may make a negative effect on the performance. Are you sure to continue? [Y/N]:y

The configuration will take effect after 2 flow intervals.
