Usage guidelines
In Release 1111, this command is supported only in system view. In Release 1121 and later, this
command is supported in system view and Layer 2 aggregate interface view.
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.
Examples
# Enable link-aggregation traffic redirection.
