Usage guidelines

When you shut down a Selected port in an aggregation group, this feature redirects traffic of the port to other Selected ports. Zero packet loss is guaranteed for known unicast traffic, but not for unknown unicast traffic.

When you restart an IRF member device that contains Selected ports, this feature redirects traffic of the IRF member device to other IRF member devices. Zero packet loss is guaranteed for known unicast traffic, but not for unknown unicast traffic.

Link-aggregation traffic redirection applies only to dynamic link aggregation groups and takes effect on only known unicast packets.

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 the device reboots.

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 aggregate interfaces. 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.
