mdc-admin

Parameters

source ip-address: Specifies the source IP address of BFD sessions.

destination ip-address: Specifies the destination IP address of BFD sessions.

Usage guidelines

An aggregation group does not support BFD if it contains interfaces on a FIP-600 module.

The source and destination IP addresses of BFD sessions must be unicast addresses. Make sure the source and destination IP addresses are consistent 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 BFD parameters configured on the aggregate interface take effect on all its member interfaces' BFD sessions. BFD sessions for link aggregation do not support the echo packet mode or the Demand mode. For more information about BFD, see High Availability Configuration Guide.

As a best practice, do not configure other features to collaborate with BFD on a BFD-enabled aggregate interface.

Make sure the number of member ports in a 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.

Examples

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

link-aggregation ignore vlan

Use link-aggregation ignore vlan to configure a Layer 2 aggregate interface to ignore VLANs.

Use undo link-aggregation ignore vlan to remove ignored VLANs from a Layer 2 aggregate interface.

Syntax

link-aggregation ignore vlan vlan-id-list

undo link-aggregation ignore vlan vlan-id-list

Default

A Layer 2 aggregate interface does not ignore any VLANs. To become Selected, a member port must have the same VLAN permit state and tagging mode as the Layer 2 aggregate interface for all VLANs.

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

Usage guidelines

To ignore the VLAN permit state and tagging mode of a VLAN when choosing Selected ports, specify the VLAN as an ignored VLAN. A member port can become Selected even if it does not have the same VLAN permit or tagging mode as the Layer 2 aggregate interface for an ignored VLAN.

Examples

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

Usage guidelines

When you restart a card that contains Selected ports in a multimodule dynamic aggregation, this feature redirects the traffic on the ports to the remaining cards. Zero packet loss is guaranteed for known unicast traffic, but not for unknown unicast traffic. (In standalone mode.)

When you restart an IRF member device that contains Selected ports in a multichassis dynamic aggregation, this feature redirects the traffic on the ports to the remaining IRF member devices. When you restart a card that contains Selected ports in a multimodule dynamic aggregation, this feature redirects the traffic on the ports to the remaining cards. Zero packet loss is guaranteed for known unicast traffic, but not for unknown unicast traffic. (In IRF mode.)

Link-aggregation traffic redirection 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.

Do not enable both spanning tree and link-aggregation traffic redirection on a device. Otherwise, light packet loss might occur when a card or the device reboots.

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

bandwidth-usage: Distributes a data flow to the Selected port that has the lowest bandwidth usage when the first packet of that data flow arrives. In this mode, each flow is identified by an IP five-tuple (source and destination IP addresses, source and destination ports, and protocol). This keyword is supported only for aggregate interfaces that use member ports on a FIP-240, FIP-300, or FIP-310 module.

per-packet: Distributes traffic on a per-packet basis.

Usage guidelines

IMPORTANT:

If you configure one aggregation group to load shard traffic based on bandwidth usage, any of the following operations might affect the traffic load sharing in the aggregation group:

· Setting the global load sharing mode.

· Setting the load sharing modes for other aggregation groups.

Make sure you are fully aware of the impacts when you perform these operations.

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

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.

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.

· Hardware limitation.

You can implement backup between two ports by performing the following tasks:

· Assign two ports to an aggregation group.

· Configure 1 as the maximum number of Selected ports allowed in 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 3 aggregation group 1.

Parameters

group-id: Specifies an existing aggregation group by its aggregate interface number.

Usage guidelines

An interface or subinterface can belong to only one aggregation group.

· If the aggregation group is for a Layer 2 aggregate interface, the member interfaces must be Layer 2 Ethernet interfaces.

· If the aggregation group is for a Layer 3 aggregate interface, the member interfaces must be Layer 3 Ethernet interfaces or subinterfaces, but not both.

If you are assigning a Layer 3 Ethernet interface to an aggregation group, make sure it does not have subinterfaces. You cannot create subinterfaces on a Layer 3 Ethernet interface after it is assigned to an aggregation group.

If you are assigning a Layer 3 Ethernet subinterface to an aggregation group, follow these restrictions and guidelines:

· You cannot assign Layer 3 Ethernet subinterfaces on a FIP-600 module to a aggregation group.

· Configure VLAN termination before you assign the subinterface to the aggregation group. You cannot modify the VLAN termination configuration after the subinterface is assigned to an aggregation group. The following are VLAN termination commands you might use:

¡ vlan-type dot1q default

¡ vlan-type dot1q untagged

¡ vlan-type dot1q vid

¡ vlan-type dot1q vid second-dot1q

For information about the VLAN termination commands, see "VLAN termination commands."

· All Layer 3 Ethernet subinterfaces in an aggregation group must have the same VLAN termination configuration.

· If you are assigning a subinterface to a dynamic aggregation group, specify only the outer VLAN ID when you use the vlan-type dot1q vid vlan-id-list [ loose ] command on that subinterface.

For a Layer 3 aggregate interface, aggregate subinterfaces and Layer 3 subinterfaces cannot coexist.

· You cannot create aggregate subinterfaces on a Layer 3 aggregate interface if its aggregation group contains Layer 3 Ethernet subinterfaces.

· You cannot assign Layer 3 Ethernet subinterfaces to an aggregation group if its aggregate interface has aggregate subinterfaces.

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 not 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.

Examples

# Specify a primary traffic processing slot for Layer 3 aggregate interface Route-Aggregation 1.
