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.
This feature ensures zero packet loss for known unicast traffic, but does not protect unknown unicast 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 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.
