show link-aggregation-status

The show link-aggregation-status command provides statistics for aggregate interfaces. To view the members in a link aggregation, use the show link-aggregation-members-status command. The output shows the following data about each aggregate interface.

• The aggregate interface's index.
• The interface's name: Kernel and configuration.
• The maximum transmission unit (MTU) for the aggregation.
• The mode for link aggregation.

  Active-backup (ab)

  The mode is active-backup. One link is active, and the other link is backup.

  LACP

  The mode uses the Link Aggregation Control Protocol (LACP). The IEEE 802.1AX-2008 (formerly IEEE 802.3ad) standard defines LACP.

  Transmit load balancing (tib)

  The mode uses transmit-based load balancing.

  Unsupported

  The mode is not supported. Contact IBM® Support.

• The link state of the aggregate interface. Values are ok or no link. If no link, the interface is not responding to the network.
• Which link, if any, is primary when the link aggregation mode is active-backup.
• The active link when the link aggregation mode is transmit-based load balancing or active-backup.
• With the LACP aggregation mode, the distribution algorithm for outbound packets among the active physical interfaces. The policy should match the configuration.

  layer2

  Indicates that the hash function uses only MAC addresses, which is layer 2 data.

  layer2+3

  Indicates that the hash function uses both MAC addresses and IP addresses. MAC addresses are layer 2. IP addresses are layer 3. This setting is the default value.

  layer3+4

  Indicates that the hash function uses both IP addresses and TCP/UDP ports. IP addresses are layer 3. TCP/UDP ports are layer 4. This approach is not strictly compliant to the LACP standard.

• With the LACP aggregation mode, the transmission rate that members send LACP frames. The rate can be either fast or slow. In LACP, the frame uses the term LACPDU.
• With the LACP aggregation mode, the selection policy. The policy should match the configuration.

  bandwith

  Chooses the aggregator with the highest bandwidth.

  count

  Selects the aggregator with the most NICs.

  stable

  Does not change the aggregator when a better one is available.

• With the LACP aggregation mode, the active aggregator's ID.
• With the LACP aggregation mode, the number of available ports for the active aggregator.
• With the LACP aggregation mode, the value of the operational key that the Actor assigned to the port.
• With the LACP aggregation mode, the value of the operational key that the Partner assigned to the port.
• With the LACP aggregation mode, the Partner's physical MAC address.
• The MII link state of the aggregation. Values are ok or no link. If no link, the interface is not responding to the network.
