network-admin
Parameters
interface-number: Specifies a Layer 2 aggregate interface number. For the S6800 switch series, S6860 switch series, and S6861 switch series, the value range for this argument is 1 to 2048. For the S6820 switch series, the value range for this argument is 1 to 256.
pex: Creates a Layer 2 extended-link aggregate interface. If you specify this keyword, the Layer 2 extended-link aggregation group can contain only extended ports that are on the PEXs in the same PEX group and at the same tier. If you do not specify this keyword, the aggregation group cannot contain PEX extended ports. For more information about PEXs, see IRF 3.1 configuration in Virtual Technologies Configuration Guide.
|
NOTE: The S6820 switch series does not support the pex keyword. |
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.
If the number of Layer 2 aggregate interfaces that you create without specifying the pex keyword reaches the hardware limit, the system displays a message about resource insufficiency. In such cases, you can attempt to create more Layer 2 aggregate interfaces by specifying the pex keyword.
You cannot specify the pex keyword when you create Layer 2 aggregate interface Bridge-Aggregation 1.

Parameters
interface-number: Specifies a Layer 3 aggregate interface number. For the S6800 switch series, S6860 switch series, and S6861 switch series, the value range for this argument is 1 to 1024. For the S6820 switch series, the value range for this argument is 1 to 256.
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 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.
Examples
# Create Layer 3 aggregate interface Route-Aggregation 1 and enter its view.

Usage guidelines
CAUTION: Changing reference port selection criteria might cause transient traffic interruption. When you use this command, make sure you understand its impact on your network. |
This command enables a dynamic aggregation group to select a high-speed member port as the reference port.
You must execute this command at both ends of the aggregate link so the peer aggregation systems use the same criteria for reference port selection.
As a best practice, shut down the peer aggregate interfaces before you execute this command and bring up the interfaces after this command is executed on both of them.
This command takes effect only on dynamic aggregate interfaces. On a static aggregate interface, you can execute this command, but the setting cannot take effect.

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.

undo link-aggregation global load-sharing mode
Default
The device selects a load sharing mode for packets depending on their packet type, as follows:
· Layer 3 (or IP) packets (frames with a value of 0x0800 or 0x86DD in the EtherType field) are load shared based on the following information:
¡ Source and destination IP addresses.
¡ Source and destination TCP/UDP port numbers.
¡ IP protocol number.
· Layer 2 packets (frames with a different value than 0x0800 and 0x86DD in the EtherType field) are load shared based on the following information:
¡ Source and destination MAC addresses.
¡ EtherType value.
¡ VLAN tag.
¡ Mod ID.
¡ Incoming and outgoing port numbers.

Parameters
destination-ip: Distributes traffic based on destination IP addresses.
destination-mac: Distributes traffic based on destination MAC addresses.
destination-port: Distributes traffic based on destination ports.
ingress-port: Distributes traffic based on ingress ports.
mpls-label1: Distributes MPLS traffic based on Layer 1 labels.
mpls-label2: Distributes MPLS traffic based on Layer 2 labels.
source-ip: Distributes traffic based on source IP addresses.
source-mac: Distributes traffic based on source MAC addresses.
source-port: Distributes traffic based on source ports.
resilient: Redistributes as less traffic as possible when a link state change occurs to minimize its impact on services. In this mode, an aggregation group distributes traffic based on the default load sharing mode when no link change occurs. When a link fails, the system rehashes the traffic on the failed link across the remaining Selected links. Because the existing traffic on the Selected links are not rehashed as in other modes, impact on the ongoing services is minimized. When the failed link recovers, the system rehashes part of the traffic on the existing Selected links to the recovered link. Because not all traffic is rehashed, the traffic distribution pattern might differ from what it was before the link failure.

Usage guidelines
IMPORTANT: This command might cause traffic loss on Selected ports operating at a speed lower than the other Selected ports in the aggregation group when traffic is distributed among the ports. 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.

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.
By default, you cannot add a port to a Layer 2 link aggregation group if it has a different VLAN permit state or tagging mode than the aggregate interface.
To have a port participate in a Layer 2 aggregation despite its difference with the aggregate interface in the settings of a VLAN, configure that VLAN as an ignored VLAN.

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.
|
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 it does not protect other types of 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 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.

flexible: Automatically chooses a load sharing mode depending on the packet type.
per-packet: Distributes traffic on a per-packet basis.
|
NOTE: The S6800 switch series does not support the per-packet keyword. |
resilient: Redistributes as less traffic as possible when a link state change occurs to minimize its impact on services. In this mode, an aggregation group distributes traffic based on the default load sharing mode when no link change occurs. When a link fails, the system rehashes the traffic on the failed link across the remaining Selected links. Because the existing traffic on the Selected links are not rehashed as in other modes, impact on the ongoing services is minimized. When the failed link recovers, the system rehashes part of the traffic on the existing Selected links to the recovered link. Because not all traffic is rehashed, the traffic distribution pattern might differ from what it was before the link failure.

Predefined user roles
network-admin
Usage guidelines
Use local-first load sharing in a multidevice link aggregation scenario to distribute traffic preferentially across member ports on the ingress card or device. Local-first load sharing takes effect only on known unicast traffic.
If you disable local-first load sharing, packets on an aggregate interface are load shared among all its Selected ports on IRF member devices.
On a VXLAN network, an aggregate interface performs only local-first load sharing in either of the following situations:
· It is a Layer 3 interface and acts as the traffic outgoing interface for a VXLAN tunnel.
· It is a Layer 2 interface in a VLAN whose VLAN interface acts as the traffic outgoing interface for a VXLAN tunnel.
For more information about VXLAN, see VXLAN Configuration Guide.

Parameters
ip-address: Specifies an IP address in dotted decimal notation.
mask: Specifies the subnet mask in dotted decimal notation.
mask-length: Specifies the mask length. The value range is 0 to 32.
Usage guidelines
Typically, an aggregate interface distributes traffic across its Selected member ports. The uplink and downlink traffic of a host might be distributed to different member ports. To make sure the bidirectional traffic of a subnet traverses the same member port, you can exclude that subnet from load sharing by specifying it as a link aggregation management subnet.
When a link aggregate interface receives an ARP packet from the management subnet, the device looks up the sender IP address in the ARP table for a matching entry.
· If no matching entry exists, the device creates an ARP entry on the aggregation member port from which the packet came in. This mechanism ensures that the returned downlink traffic will be forwarded out of the member port that received the uplink traffic.
· If an ARP entry already exists on a different port than the link aggregate interface or its member ports, the device does not update that ARP entry. Instead, the device broadcasts an ARP request out of all ports to relearn the ARP entry.
When a link aggregate interface sends an ARP packet to the management subnet, the device sends the packet out of all Selected member ports of the link aggregate interface.
You can configure a maximum of 20 management subnets.
To ensure correct packet forwarding, delete all ARP entries of a subnet before you specify it as a management subnet or after you remove it from the management subnet list.
If you are using link aggregation management subnets, do not use the following features:
· DRNI. For more information, see Layer 2—LAN Switching Configuration Guide.
· ARP snooping. For more information, see Layer 3—IP Services Configuration Guide.
· MPLS L2VPN. For more information, see MPLS Configuration Guide.

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.
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.

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 32.
percentage number: Sets the minimum percentage of Selected ports in an aggregation group. The value range for the number argument is 1 to 100.
Usage guidelines
IMPORTANT: After you set the minimum percentage of Selected ports for an aggregation group, aggregate interface flapping might occur when ports join or leave an aggregation group. Make sure you are fully aware of the impacts of this setting when you configure it on a live network. |
You can set either the minimum number or the minimum percentage of Selected ports for an aggregation group. If you configure both settings on an aggregate interface, the higher Selected port number limit takes effect.
Executing this command might cause all member ports in the aggregation group to become Unselected ports.
You must set the same minimum number or minimum percentage of Selected ports at the two ends of an aggregate link.
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 2 aggregation group 1.

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 300 seconds.
· If you specify the msec keyword, the value range is 0 to 10000 milliseconds, and the value must be a multiple of 100.
Usage guidelines
You can configure this feature to suppress link-down events, link-up events, or both. If an event of the specified type persists 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.
As a best practice to reduce the impact of interface flapping on upper-layer services, use this command on the following aggregate interfaces:
· DRNI IPPs. For more information about IPPs, see Layer 2—LAN Switching Configuration Guide.
· Aggregate interfaces that act as cascade ports in an IRF 3.1 system. For more information about IRF 3.1, see Virtual Technologies Configuration Guide.

Usage guidelines
By default, the device drops a packet if its outgoing interface is the incoming interface where the packet arrived. Port bridging enables a Layer 2 aggregate interface to reflect a packet back when it is both the incoming and outgoing interfaces of that packet.
Examples
# Enable port bridging on Bridge-Aggregation 1.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] port bridge enable
port link-aggregation group
Use port link-aggregation group to assign an interface to an aggregation group.
Use undo port link-aggregation group to remove an interface from the aggregation group to which it belongs.
Syntax
port link-aggregation group { group-id [ force ] | auto [ group-id ] }
undo port link-aggregation group
Default
An interface does not belong to any aggregation group.

Parameters
group-id: Specifies an aggregation group by its aggregate interface number. For the S6800 switch series, S6860 switch series, and S6861 switch series, the value range for this argument is 1 to 2048. For the S6820 switch series, the value range for this argument is 1 to 256.
force: Enables the current interface to synchronize attribute configurations from the aggregate interface. If you do not specify this keyword, the current interface does not synchronize attribute configurations from the aggregate interface when it joins the aggregation group. This keyword is supported only on Layer 2 Ethernet interfaces and S-channel interfaces.
auto: Enables automatic assignment.
Usage guidelines
A Layer 2 Ethernet interface can be assigned only to a Layer 2 aggregation group. A Layer 3 Ethernet interface can be assigned only to a Layer 3 aggregation group. An S-channel interface can be assigned only to an S-channel bundle group.
An interface can belong to only one aggregation group.
An interface cannot join an aggregation group if it has different attribute configurations from the aggregate interface. After joining an aggregation group, an interface inherits the attribute configurations on the aggregate interface. You can modify the attribute configurations only on the aggregate interface.
The force keyword takes effect only when you assign the interface to an aggregation group. It cannot be saved in the running configuration or a configuration file.
Automatic assignment is available only on Layer 2 and Layer 3 Ethernet interfaces.
When you enable automatic assignment, you can specify a preferred aggregation group, which must be in dynamic mode.
The device assigns the interface to the preferred aggregation group as long as the LACPDUs received on the interface match the peer information of the reference port in the group.
If you do not specify a preferred group or if the preferred group match fails, the device attempts to select a matching group from the existing dynamic aggregation groups. If no match is found, the device creates a dynamic aggregation group based on the LACPDUs and assigns the interface to that aggregation group.
As a best practice, do not modify the configuration on an automatically created aggregate interface or its member ports.
Examples
# Assign Layer 2 Ethernet interface Ten-GigabitEthernet 1/0/1 to Layer 2 aggregation group 1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] port link-aggregation group 1
# Assign Layer 3 Ethernet interface Ten-GigabitEthernet 1/0/2 to Layer 3 aggregation group 2.

port s-mlag group
Use port s-mlag group to assign an aggregate interface to an S-MLAG group.
Use undo port s-mlag group to restore the default.
Syntax
port s-mlag group group-id
undo port s-mlag group
Default
An aggregate interface is not in any S-MLAG group.

Parameters
group-id: Specifies an S-MLAG group number in the range of 1 to 1024.
Usage guidelines
You can assign only Layer 2 aggregate interfaces in dynamic mode to an S-MLAG group.
Each S-MLAG group can contain only one aggregate interface on each device.
The aggregate interfaces in an S-MLAG group cannot be used as DR interfaces or IPPs in DRNI. For more information about DR interfaces and IPPs, see DRNI configuration in Layer 2—LAN Switching Configuration Guide.
Examples
# Assign Bridge-Aggregation 1 to S-MLAG group 1.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] port s-mlag group 1

Parameters
bridge-aggregation: Specifies Layer 2 aggregate interfaces.
route-aggregation: Specifies Layer 3 aggregate interfaces.
schannel-bundle: Specifies S-channel bundle interfaces.
interface-number: Specifies an existing aggregate interface number.
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 in the system.
If you specify only an aggregate interface type, the command clears statistics for all aggregate interfaces of the specified type.
The bridge-aggregation, route-aggregation, or schannel-bundle keyword is available only when aggregate interfaces of the corresponding type exist on the device.
Examples
# Clear the statistics about interface Bridge-Aggregation 1.
<Sysname> reset counters interface bridge-aggregation 1
reset lacp statistics

Usage guidelines
The packet statistics feature is CPU intensive. When you use this command for Layer 3 aggregate subinterfaces, make sure you fully understand its impact on system performance.
You can use the flow-interval command to adjust the interval at which the statistics are polled. To conserve hardware resources, increase the polling interval. For more information about this command, see Ethernet interface commands in Interface Command Reference.
This feature collects only incoming packet statistics on Layer 3 aggregate subinterfaces.
To view the packet statistics for a Layer 3 aggregate subinterface, see the Input and Output fields in the output from the display interface command.
Examples
# Enable packet statistics on Route-Aggregation 1.1.
<Sysname> system-view
[Sysname] interface route-aggregation 1.1
