Use undo interface bridge-aggregation to delete a Layer 2 aggregate interface.

Syntax

interface bridge-aggregation interface-number [ lite ]

Default

No Layer 2 aggregate interface is created.

Views

System view

Predefined user roles

network-admin

mdc-admin

Parameters

interface-number: Specifies a Layer 2 aggregate interface number in the range of 1 to 16384.

lite : Specifies a lite Layer 2 aggregate interface, which is a special aggregate interface in IRF mode. If you do not specify this keyword, the system creates a generic Layer 2 aggregate interface.

Usage guidelines

When you configure a Layer 2 aggregate interface, follow these restrictions and 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.

· If you delete the Layer 2 aggregate interface, you also delete the Layer 2 aggregation group, and any member ports leave the aggregation group.

· To create a lite or a generic Layer 2 aggregate interface, delete the generic or the lite Layer 2 aggregate interface with the same aggregate interface number first.

When you configure a lite Layer 2 aggregate interface, also follow these restrictions and guidelines:

· You can create a lite Layer 2 aggregation group only in IRF mode. An IRF fabric supports up to 1024 lite Layer 2 aggregation groups. Each IRF member device can have a maximum of one Selected port in a lite Layer 2 aggregation group. The maximum number of Selected ports in a lite Layer 2 aggregation group is identical to the number of member devices.

· Make sure a port has no manually configured MAC address entries before assigning the port to a lite Layer 2 aggregation group.

· Do not manually modify or delete the MAC address entries of a port in a lite Layer 2 aggregation group. Otherwise, traffic cannot be forwarded correctly.

· In IRF mode, do not configure a lite Layer 2 aggregation group and an isolation group on the same device. Otherwise, traffic cannot be forwarded correctly. For more information about port isolation, see "Configuring port isolation."

· You cannot enable EVI on a member port in a lite Layer 2 aggregation group. Moreover, do not assign a transport-facing physical interface of an EVI tunnel to a lite Layer 2 aggregation group. Otherwise, traffic cannot be forwarded through the EVI tunnel. For more information about EVI, see EVI Configuration Guide.

· A lite Layer 2 aggregate interface cannot operate as an OpenFlow port. For more information about OpenFlow, see OpenFlow Configuration Guide.

interface route-aggregation

Use interface route-aggregation to create a Layer 3 aggregate interface or subinterface and enter Layer 3 aggregate interface or subinterface view.

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

Syntax

Parameters

interface-number: Specifies a Layer 3 aggregate interface number in the range of 1 to 16384.

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 4094 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.

You cannot create Layer 3 Ethernet interfaces or subinterfaces, or Layer 3 aggregate interfaces or subinterfaces in the following cases:

· The system is operating in standard mode. For more information about switch's operating modes, see Fundamentals Configuration Guide.

· The switch is operating in IRF mode and the enhanced IRF mode is enabled. For more information about IRF and the enhanced IRF mode, see Virtual Technologies Configuration Guide.

Deleting the 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.

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.

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

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

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

mpls-label3: Load shares MPLS traffic based on Layer 3 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 by packet.

Usage guidelines

The load sharing mode that you configure overwrite the previous mode.

Ingress-port load sharing cannot cooperate with any other modes.

Per-packet load sharing is not configurable in IRF mode. Because per-packet load sharing might disorder the packets, H3C recommends not configuring per-packet load sharing when the internal interface on the OAP card belongs to an aggregation group. For more information about the OAP card, see OAA Configuration Guide.

All load sharing modes (except mpls-label1, mpls-label2, mpls-label3, and per-packet) take effect on ECMP load sharing of unicast traffic. If per-packet load sharing is configured, ECMP load sharing is performed according to the default load sharing modes supported by the switch. For more information about ECMP, see Layer 3—IP Routing Configuration Guide.

Examples

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

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 ID for vlan-id2 must be equal to or greater than the ID for vlan-id1.

Usage guidelines

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

[Sysname] interface bridge-aggregation 1

Usage guidelines

This command can be configured only on devices in IRF mode.

The maximum number of aggregated links in an aggregation group is subject to either of the following values, whichever is smaller:

· Maximum number configured by using the link-aggregation selected-port maximum command.

· The hardware limitation.

The hardware limitation varies depending on the following situations:

· If this command is not configured, the value is the maximum number supported by one IRF member device.

· If this command is configured, the value is the maximum number supported by one member device multiplied by the number of member devices.

If one end is configured with this command, make sure the other end is also configured with this command. Otherwise, link aggregation might not operate if the local end has more eligible Selected ports than the maximum number allowed. When both ends are configured with this feature, the smaller maximum number of Selected ports allowed applies.

Do not use this command when you configure backup between two ports in an aggregation group. Otherwise, backup between two ports does not take effect. Backup between two ports is implemented when you assign two ports to an aggregation group and configure the maximum number of Selected ports allowed in the aggregation group as one.

Examples

# Enhance the Selected port capacity for link aggregation in IRF mode.

<Sysname> system-view

[Sysname] link-aggregation irf-enhanced

link-aggregation mode

Use link-aggregation mode dynamic to configure an aggregation group to operate in dynamic aggregation mode and enable LACP.

Use undo link-aggregation mode to restore the default.

Syntax

Parameters

number: Specifies the maximum number of Selected ports allowed in an aggregation group, in the range of 1 to 48.

Usage guidelines

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

The maximum number of Selected ports allowed in the aggregation groups of the local and peer ends must be consistent.

The maximum number of Selected ports allowed in an aggregation group is limited by one of the following values, whichever is smaller:

· Maximum number configured by using the link-aggregation selected-port maximum command.

· Hardware limitation.

You can configure 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.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

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